DC Current Measurements
£,WARNING: Observe all safety precautions when working on live
circuits . Do not measure current on circuits that exceed 600V . Measurements
in the 1 OA range should be limited to 30 seconds maximum every 15 minutes
when the current is under 5A and should be limited to 10 seconds maximum
every 15 minutes when the current is equal to or greater than 5A .
1. Insert the black test lead into the COM input jack.
2. For current measurements up to 1 QA DC, set the rotary function switch to
the 1 OA =-=-= range and insert the red test lead into the 1 OA input jack .
3. For current measurements up to 200mA DC, set the rotary function switch
to 200mA =-=-= range and insert the red test lead into the mA input jack .
4. Remove power from the circuit under test, then open up the circuit at the
point where you wish to measure current.
5. Connect the black test probe tip to the negative side of the circuit. Connect
the red test probe to the positive side of the circuit.
6. Apply power to the circuit.
7. Read the current in the display .
8. If desired when using the 200mA setting, turn the rotary function switch to
successively lower positions (20mA , then 2000µA) to obtain a more precise
reading . If the polarity is reversed, the display will show a(-) minus sign
infront of the reading .
