(the storage capability is always active.) display modes: track: display follows input voltage. peak-hold: displays one of the stored peak values. max: selects the max stored value. min: selects the min stored value. accuracy step input: 0.1% 4 counts for step input up to 15v >4 msec duration. repetitive step input: 0.1% 4 counts for repetitive step inputs of >300 sec duration. minimum number of steps required: 4 msec pulse duration. repetitive sine wave: 5% 4 counts for repetitive sine wave input of <1000 hz. 0.5% 4 counts for repetitive sine wave input of <100 hz. hold stability <1 count/minute typical, 2 counts/minute maximum averaged over 5-minute period. reset capability manual or automatic timed reset of max and min peaks. optoisolator input requires 2 to 30v (<5 ma @ 5v) for 0.1 msec minimum. power 115/230 vac, 50-60 hz, 10w max. size & weight 7h x 3.44 w x 17.88 d [178 x 87.5 x 454 mm]; 4.4 lb [2.0 kg]. all specifications are nominal or typical at +23 c unless noted.
