4.4. DC Current Measurements
Caution:
Do not make current measurements on the 20A scale for
longer than 30 seconds. Exceeding 30 seconds may cause
damage to the meter and/or the test leads.
1. Insert the black test lead banana plug into the negative (COM)
jack.
2. For current measurements up to 200mA DC, set the function
switch to the mA range and insert the red test lead banana plug
into the (mA) jack.
3. For current measurements up to 20A DC, set the function switch
to the A position and insert the red test lead banana plug into the
20A jack.
4. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
5. Touch the black test probe tip and the red test probe tip in series
to the circuit whose current you want to measure.
6. Apply power to the circuit.
7. Read the current on the display. The display will indicate the
proper decimal point value.
4.5. AC Current Measurement
Warning: To avoid electric shock, do not measure AC current on any
circuit whose voltage exceeds 250V AC.
Caution: Do not make current measurements on the 20A scale for
longer than 30 seconds. Exceeding 30 seconds may cause
damage to the meter and/or the test leads.
1. Insert the black test lead banana plug into the negative (COM)
jack.
2. For current measurements up to 200mA AC, set the function
switch to the mA range and insert the red test lead banana plug
into the (mA) jack.
3. For current measurements up to 20A AC, set the function switch
to the A position and insert the red test lead banana plug into the
20A jack.
4. Remove power from the circuit under test, then open up the
circuit at the point where you wish to measure current.
5. Touch the black test probe tip and the red test probe tip in series
to the circuit whose current you want to measure.
