Digitize current verification
For Digitize DC current verification, you use different connections and procedures to test the 10 µA
and 100 µA ranges and the 1 mA to 3 A ranges than the measure DC current verification.
Digitize DC current 10 µA and 100 µA range verification
To verify digitize DC current accuracy for the 10 µA to 100 µA ranges, you will:
• Apply accurate DC voltage from the calibrator through a precision shunt resistor to the Model
DMM7510 front terminals.
• Sense the voltage across the shunt with a reference DMM.
• Verify that the displayed readings of the Model DMM7510 fall within the calculated reference
DMM voltage and precision shunt limits.
