Voltage Measurements
1. Connect the red test lead to the "V
W
" jack and the black test lead to the
"COM" jack.
2. Set the Function/Range switch to the desired voltage function.
3. Connect the test leads to the device or circuit being measured.
4. For dc, a (-) sign is displayed for negative polarity; positive polarity is implied.
Current Measurements
1. Set the Function/Range switch to the desired current range and press the
A toggle button to select AC or DC.
2. For current measurements less than 400mA, connect the red test lead to the
mA jack and the black test lead to the COM jack.
3. For current measurements of 400mA or greater, connect the red test lead
to the 10A jack and the black test lead to the COM jack.
4. Remove power from the circuit under test and open the normal circuit path
where the measurement is to be taken. Connect the meter in series with the
circuit.
Resistance and Continuity Measurements
1. Set the Function/Range switch to the resistance function.
2. Remove power from the equipment under test.
3. Connect the red test lead to the "V
W
" jack and the black test lead to the
"COM" jack.
4. Touch the probes to the test points. In ohms, the value indicated in the
display is the measured value of resistance.
5. The beeper sounds continuously, if the resistance is less than 50
W
±30
W
