C when measuring temperature with respect to any temperature calibrat or, try to set both the calibrator and tester with an external reference (without internal ambient compensation). if both the calibrator and t ester are set with internal reference (with internal ambient compensa tion), some deviations may show between the readings of the calibrator and teste r, due to differences in ambient compensation between the calibrator and tester. keeping the tester close to the output terminal of calibrator w ill help reduce the deviation.
