* 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.
