Resistance/Current Ranges
The green resistance ranges on the keypad indicate low output power (<0.25 W) outputs.
Red ranges indicate higher 2.5 W (1 A) and 25 W
(10 A) power outputs.
Resolution and Accuracy
Test current accuracy
±10%
Voltmeter input impedance >200 kΩ
Max. lead resistance at 10 A <100 mΩ
* The accuracy stated assumes forward and reverse measurements.
Inductive mode or undirectional mode will introduce an undefined error if an external EMF is present.
Basic accuracy at reference conditions.
