5. Connect test leads in series with the circuit to be measured.
6. Read the reading on the display. For DC current measurement, the
polarity of the red test lead connection will be indicated as well.
Note: When the display shows the over range symbol "OL", a higher range
must be selected.
MEASURE RESISTANCE
1. Connect the black test lead to the "COM" jack and the red to the "INPUT"
jack (Note: The polarity of the red test lead is positive "+").
2. Set the range switch to " " position, press "Select" button to select
" " function.
3. Select auto range or manual range with the "Range" button. In manual
range, if the current magnitude to be measured is not known beforehand,
select the highest range.
4. Connect the test leads across the load to be measured.
5. Read the reading on the LCD.
Note:
a. For resistance measurements > 1 M , the Digital multimeter may take a
few seconds to stabilize reading. This is normal for high-resistance
measurement.
b. When the input is not connected, i.e. at open circuit, the symbol "OL" will
be displayed as an over range indicator.
c. Before measuring in-circuit resistance, be sure that the circuit under
test has all power removed and all capacitors are fully discharged.
CONTINUITY TEST
1. Connect the black test lead to the "COM" jack and the red to the "INPUT"
jack (Note: The polarity of the red test lead is positive "+").
2. Set the range switch to " " position.
3. Press the "Select" Button to select continuity measurement mode, and
the symbol " " will appear as an indicator.
4. Connect the test leads across the load to be measured.
5. When the circuit resistance is lower than about 30 , the built-in
buzzer will sound.
