Battery Cell Insulation Tester 11210 User’s Manual
2-2
• Temperature: 23ºC ± 5ºC
• Relative Humidity: 75% maximum
• Warm up: 30 minutes minimum
• Test condition for accuracy specification: measurement speed with integration time of
500ms.
• Guarantee only for the tests on pure resistive DUT.
Accuracy of IR measurement:
It is calculated based on the accuracy of leakage current measurement and voltage
measurement. For detailed descriptions, see Appendix B IR Accuracy.

2.1.7 LC Null
It eliminates the leakage current of the entire measuring loop to add the measurement
accuracy before connecting DUT for test.
2.1.8 Contact Check
Make sure the leakage current test end of the tester and DUT are connected.
