Resistance
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.
Test Voltage Accuracy: -0%,+20%
Short Circuit Test Current: 1mA(nominal)
Auto discharge function: discharge time <1 sec for C <1μF
Maximum Capacitive load: Operable with up to 1μF load
Live Circuit Detection: if >30V ac/dc at inputs, test inhibited
