• Do not measure voltage with the 10A input; do not measure AC current on circuits with AC
250V or above voltage.
• When using the 10A current range, the measurement time should not exceed 15 seconds every 15
minutes, otherwise the meter and test probes may be damaged.
1. Insert the connecting plug of the black test probe into the negative
COM jack and insert the banana plug of the red test probe into
the positive mA jack. (Insert into the 10A jack when measuring
10A current)
2. Rotate the function switch based on the size of the test signal
and point the arrow on the knob to the 400mA/10A range.
3. Press the “SELE” button to select the AC or DC measurement.
When selected, the ~ or symbol will appear in the upper left
corner of the screen.
4. Connect the test probes into the circuit under test in series.
5. Read the current value displayed on the meter. The displayed results
include values, decimal points, and polarity.
