Compatibility with 8840 floppy disk data Data measured with the MEMORY HiCORDER 8840 and stored on floppy disks can be read to the 8841 and 8842 and processed with the functions offered by these models.
* Data measured using the 8841/8842 cannot be used with the 8840.
Large-capacity memory In the standard memory configuration, a total of 8 mega-words can be stored. With expansion memory installed, capacity is a full 32 mega-words. This provides for up to 2 mega-words per channel when 16 channels are used. Even with high-speed sampling, long-term recording is possible. 10.4 inch color TFT display for easy visual identification The color display makes it easier to identify waveforms and eases installation of devices, and makes the unit all the more easier to operate.
A LAN-Connectable Recorder! Digitally Process Test Data
With a conventional pen recorder, even if all test data is written on the paper, usually only a small portion of the data is needed. However, to look for just a small important part requires very extensive search of the recording paper. MEMORY HiCORDER 8841, 8842 stores and manages all waveform measurement data electronically. Furthermore, use of a LAN card and LAN COMMUNICATOR 9333 enables high-speed data file transfer to PCs on a ne-twork.
Example of using measurement data in Excel
Monitors non-visual (mechanical or electrical) operations and provides support to solving problems - Application Research and development of automobiles (8841)
In vehicle and engine running tests, the relationship among various parameters must be examined. Multi-channel recorders are necessary to accomplish this. While 8841 has retained the size of its predecessor, the 8840, it allows recording with 16 analog channels + 16 logic channels. Using the DC POWER ADAPTER 9433 enables operation using the vehicle's battery (+12 V/+24 V).

Engine tuning Allows the balance between boost, oil pressure, air fuel ratio, ignition timing, engine speed, injector aperture, etc., to be observed and recorded as waveforms. Analysis of engine characteristics
The pressure waveforms of injection pipes and fuelinjection pumps, etc., can be recorded and stored in the internal memory and then superimposed on a reference waveform for analysis.
Evaluation of electrical circuits Quality evaluation of meter boards for use in automobiles can be performed by recording and evaluating analog waveforms. Waveform judgment
After defining a reference waveform bounding area, it is possible to check whether waveforms go outside this reference area. As opposed to simple voltage levelbased triggering, even complex waveforms can be evaluated quickly and reliably, because both the level direction and the time axis direction are taken into consideration simultaneously. * Registered patent no. 2028013, in Japan
Evaluation of machines and materials
Pressure waveforms can be measured and recorded simultaneously at various points of hydraulic machines to determine whether such machines are operating normally. Using, for example, the recorder's X-Y recording function, performance dispersion check can be conducted by recording the relationship between one cycle operation command signal for an injection molding machine, the pressure and the position change.
Analysis of injection molding machine operation
The quality of molded products can be evaluated by recording the relationship between the injection molding machine's operation command and the pressure and position change.
Recorder function X-Y display
The recording time is unlimited in the case of recording an X-Y plot of two analog channels. The channel combination is arbitrary. The X-Y plot can be viewed on the screen, and it can also be printed out as many times as desired, making this more useful than what is offered by standard X-Y recorders.
Analysis of tensile tests
When conducting stretching characteristic test and tensile test of steel tubing, the relationship between load and contraction can be recorded.
Recording of motor rush current
The rush current occurring when the power to a motor or a relay is turned on can be accurately measured as a waveform.
Servo-controller analysis
The operation of a servo-controller utilizing a PWM inverter and used to control a general motor can be accurately measured as a waveform.
Fast response recorder function
The 8841 and 8842 have a recording function which can print out data onto paper in real-time. Recording continues until the recording paper (30 m per roll) is used up. The recorder functions offered by the 8841 and 8842 outperform others in the way that the recorder's pen response is extremely fast in relation to the sampling speed. The maximum sampling speed is 1 s, which is the same as the memory recorder function speed.

- Application Vibration analysis
When installing rotating machinery, such as agitators, that create many vibrations, damping precautions are normally taken to ensure that the vibrations are not propagated directly to the floor surface. Analysis of the vibration damping measures and effects can be conducted by measuring the natural frequency and the transfer function.
Measurement of the damping of vibrations reaching the solid base from the rotating machinery
By striking the agitator with an impulse hammer, the vibrations propagated to the solid base can be measured by the acceleration speed pick up. Finding the transfer function can show to what extent specific frequencies are being dampened.
FFT analysis function
FFT capability includes single-signal FFT for analyzing frequency components, two-signal FFT for transfer function analysis, and octave analysis for acoustic analysis. The source signal can be selected from waveform data captured by the memory recorder, and isolating required sections is also possible. (Number of data points: 1000 - 10000)
Rotation frequency
Measurement of the natural frequency of objects
Resonance phenomena can be avoided by ensuring that the natural frequency of an object is different from the vibration frequency of the surroundings. By striking the object with an impulse hammer and finding the transfer function, the natural frequency of the object can be found.
Load shutdown tests in power generation plants and inspection of electric systems
For load shutdown tests in power generation plants, the pre-trigger function can be used to measure and record waveforms before and after the test, enabling accurate analysis. The vernier function, which can be used to perform fine adjustment of amplitudes, is also a useful tool. In the field of electricity, the recorders have many applications, such as recording of rush current frequency, recording of breaker activation timing, and monitoring of power lines for irregularities.
Load shutdown test
Analysis of the relationship between the generator voltage, rotation speed regulation, governor servo operation condition, and the open and close timing of the pressure regulator before and after load shutdown can be performed.
Memory recorder function
The input signal is converted to digital form and stored in the internal memory. It can then be displayed on the screen or printed out on paper. Since the recordable signal speed is determined by the sampling rate and the memory saving rate, it is simple to capture even very fast transient events that escape normal recorders.
All channel inputs isolated CB timing measurement
For inspection of the shutdown timing of circuit breakers for electrical circuits, the relations between logic signals and analog waveforms of multiple points can be analyzed.
close command Phase R
Each channel has its own dedicated A/D converter, allowing simultaneous sampling in all 16 analog channels and in all 16 logic channels.
Phase S
Phase T
Momentary loss of power recording
Momentary loss of power in power-supply circuits can be recorded by using the voltage drop detection trigger, thus enabling accurate waveform recording of unexpected events.
RMS recorder function
This function is exclusively for use on 50/60 Hz powersupply lines and DC. High-speed sampling is applied to calculate the rms value from the waveform data, and the result is recorded as a graph.
*Using 200 s high-speed sampling, data for two waveforms are captured for calculating the rms value. This process is repeated 20 times per second, resulting in high-speed response that is 10 times faster than that of a digital tester or similar (using a 2-second update rate).
Ground fault line detection
To identify the ground fault line of transmission lines, measurement can be conducted using the trigger that combines a leak current meter and the recorder. This allows observation and recording of the waveform before and after ground faulting to identify the line.

High-Speed Response for Capturing Transient Events
- Function Details Large memory capacity allows long-term recording of high- speed data
In the standard configuration, the 8841 and 8842 can store a total of 8 mega-words, and with memory expansion 32 megawords, using internal solid-state memory. This provides ample capacity to store data for all 16 channels. The table at right shows possible recording times, according to the time axis setting and the number of channels in use. A reduction in the number of channels prolongs the recording time.
* The table applies to the standard memory configuration. When the optional MEMORY BOARD 9608 is installed, recording times are extended by a factor of 4 (from 16 mega-words/channel, 160,000 divisions for 2 channels to 2 mega-words/channel, 20,000 divisions for 16 channels).

Memory segmentation function
When using the memory recorder function, the data memory can be divided into a maximum of 255 blocks. Data can be written sequentially to the memory blocks, and the waveform in a reference block and any other block can be superimposed and compared.
* In the standard memory configuration (8 mega-words), the maximum number of blocks using the 16 channel setting is 127. When the memory expansion is installed, or when the channel setting is 2 to 8, the maximum number of blocks is 255.

Zoom function
*In memory recorder function
To make the most of the large-capacity memory, it is possible to display a compressed waveform simultaneously with a magnified waveform. Since the 8841 and 8842 are capable of storing a large amount of data, high-speed sampling is also possible for waveforms with a long duration. Accordingly, while observing the compressed image of the entire waveform, it is also possible to observe the magnified details of desired parts. Compressed display of a part of the entire waveform is also possible.
Clock input for external sampling
*In memory recorder function
The sampling rate for the memory recorder can be controlled by the timing of an external clock signal. This is useful for example to collect data synchronized to the running cycle of an engine.

Support for connection to PCs via Ethernet
8841/8842 can be connected to Ethernet, a standard network protocol in the Internet age (using the optional LAN CARD and LAN COMMUNICATOR 9333). For those who frequently analyse measurement data on PCs, this function offers a good match. Also, connection to PCs using RS-232C connection or GP-IB connection is possible (using the optional RS-232C CARD 9557 and GP-IB CARD 9558). 8841/8842 data can be sent to PCs or be remotely controlled from PCs.
* Because LAN card, GP-IB card, and RS-232C card all use the same PC card slot of 8841/8842, when one of them is inserted into the PC card slot, then any memory card cannot be used at the same time.

Offline data exchange with PCs
The supplied waveform viewer (PC application) can convert saved waveform data to text files (CSV format). For data storage, FD/PC card (supplied as standard) can be used. This allows easy offline data exchange with PCs.
* In addition to HiCORDER's read/write native file (binary format), data can also be saved to text files (CSV format) which can be opened by PC spreadsheet applications, or waveform bitmap files (BMP format). However, because data saved in text files cannot be read by HiCORDER, it is recommended that text data conversion be performed on PCs.

Scaling Functions
Actual measurements usually involve parameters other than voltage. Various physical parameters such as speed, vibration and temperature commonly need to be recorded, and this signal data should be directly readable, without having to be manually converted. In such measurement conditions, the scaling function can be used to automatically convert to the desired parameter value. Additionally, waveform amplitude can be adjusted using the Variable Gain function. In addition, if accurate input voltage amplitude measurement is not required, the amplitude can be intentionally modified with the Vernier Adjustment function.

Real time save function *supported in version 2.60 or later
The real time save function enables data to be saved to the PC card while waveform is being measured. The compressed waveform is displayed on the screen at real time. This function is valid at the recorder and memory function. Write to the PC card can be up to 2kS/s (=50ms/DIV) for 8 channels, or up to 1kS/s (100ms/ DIV) for 16 channels. With the real time save function, data measured at the pre-determined sampling below the maximum sampling can be saved to the PC card at any time. In addition, since the same data is compressed along the time axis and displayed on the screen, you can check how recording is going. Compressed data is saved to the PC card for later retrieval.

Storage data (MEM waveform) : Save measurement data to the PC card at real time
Time axis setting(MEM): 50 ms/DIV to 5 minutes/DIV (sampling frequency starting from 2 kS/s for 8 channels or from 1 kS/s for 16 channels) Recording length setting (MEM): depending on free capacity of the PC card.

Storage data (REC waveform) : Save compressed data to the PC card after measurement
Time axis setting(REC): 200 ms/DIV to 1 hour/DIV (sampling frequency starting from 2 kS/s for 8 channels or from 1 kS/s for 16 channels) Recording length setting (REC): up to 1000 DIV (or up to 5000 DIV with memory expansion)
Display data (REC waveform): compressed waveform is displayed on screen Compressed data is saved temporarily in the internal memory.
However, display time axis of REC data is 2 steps later than that of MEM data. The maximum recording time that can be set is determined by the free capacity of the PC card, and the time axis and recording length of MEM/REC. Nevertheless, since the maximum recording length of REC is fixed at 1000 DIV, or 5000 DIV if there is memory expansion, even if there is plenty of free capacity on the PC card, the recording time cannot exceed the value determined by REC time axis multiplied by 1000 DIV.
Trigger functions capable of monitoring all 16 channels
For all of the measurement functions, including record and memory recorder, triggers can be set on all 16 channels. In addition to a simple level trigger based on comparison with a single voltage value, the following trigger functions are also available:
* Window trigger based on 2 voltage values * Voltage drop trigger for AC power lines * Level trigger based on rms values * Cycle trigger monitoring the rising edge of a voltage * Pattern trigger monitoring the Hi/Low condition of a logic signal
