Hi here is my first tryout to measure current in a DMM in order to check its power drain using a almost fresh NIMH cell.. a newbie one...
Conditions....:
. DMM: Uni-t 204A clamp meter.
- Cell: 9V NIMH 220mAh
- Leads: Using old aligator leads plugged to terminais ( plan to user newer ones or dummy cell)
- Current Measurement: Multimeter Unit-50b in 20 mA scale in series with battery + standard test leads + old aligator clips
- Voltage Measurement ( Battery and DMMterminais) : Uni-t 120C
Measurements
- Check attachments .. in portuguese... sorry
- Battery Voltage measurement on battery and contacts was taken on the 40A DC
Further tests involves switching aligators clips,test leads, dummy cells. Measurement multimeters for better accuracy on the results.
