MEASURING PROCEDURE
Current Source
•
Insert the black test lead into the negative (COM) jack and the red test lead into the
positive (mV-mA) jack.
•
Set the function switch to current (mA source) position.
•
Press the 0-19.9mA button to set the 0.01mA display resolution (max display is
19.99mA) or press the 0-24mA button to set the 0.1mA display resolution.
•
Adjust the calibration rotary control (CAL ADJUST) to generate the current output.
Current Measurement
•
Insert the black test lead into the negative (COM) jack and the red test lead into the
