* Above specifications only apply when high quality silicone

leads with test clips are being used with no hands touch.

Test Voltage vs. Maximum resistance range :

50V/50.0MΩ,100V/100.0MΩ,250V/250.0MΩ,500V/500MΩ and

1000V/20.0GΩ.

Test Voltage vs. Minimum resistance (with test

current=1mA) :

50V/50kΩ,100V/100kΩ,250V/250kΩ,500V/500kΩ and

1000V/1MΩ.
