DC CURRENT MEASUREMENTS
CAUTION:
Do not make 10A current measurements for longer than 15 seconds;
Exceeding 15 seconds may cause damage to the meter and/or the test leads. Always
turn the meter OFF for 15 minutes before measuring again.
WARNING:
Never measure current above 600mA in the µA/mA range and 10A in the
10A range. The voltage in the measurement circuit must not exceed 1000VDC
1.
Insert black test lead banana plug into the negative
COM
jack.
2.
For current measurements up to 6000µA DC, set the function switch to the
µA
position and insert the red test lead banana plug into the
µA/mA
jack.
3.
For current measurements up to 600mA DC, set the function switch to the
mA
position and insert the red test lead banana plug into the
µA/mA
jack.
4.
For current measurements up to 10A DC, set the function switch to the
10A
position and insert the red test lead banana plug into the
10A
jack.
5.
Press the
M
button to indicate (DC) on the display.
6.
Remove power from the circuit under test, then open up the circuit at the point
where you wish to measure current.
7.
Touch the black test probe tip to the negative side of the circuit. Touch the red test
probe tip to the positive side of the circuit.
8.
Apply power to the circuit and read the current on the display.
