b. In manual range, when the multimeter shows “OL” or Over Range, you must select a
higher range in order to get results.
c. To avoid damage to the meter, do not measure voltage exceeding 600V DC or 600V AC
CATIII.
Current Measurement
1. Connect the black test lead to the “COM” jack. If the current to be measured is less than
600mA, connect the red test lead to the “mA” jack. If the current is between 600mA and
10A, connect the red test lead to the “10A” jack instead.
2. Set the function switch to necessary range (µA, mA, or A). If the current magnitude to be
measured is not known beforehand, set the function switch to the highest range and
then reduce it range by range until a satisfactory resolution is obtained.
3. Select DC current measurement or AC current measurement with the “Select” Button.
a. There is no option to change between manual and automatic ranges for current
measurements.
4. Connect the test leads to the source or load to be measured.
5. Read LCD display. The polarity of the red test lead will be indicated.
Resistance Measurement
1. Connect the black test lead to the “COM” jack and the red test lead to the “INPUT ” jack.
2.
Set the function switch to “
” range.
3. Select either Auto or Manual range with the “Range” button. In manual range, if the
Resistance magnitude to be measured is not known beforehand, select the highest
range.
4. Connect the test leads to the source or load to be measured.
5. Read LCD display. The polarity of the red test lead will be indicated.
Note:
a. For resistance measurements
>1MΩ,
the meter 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 test lead to the “INPUT ” jack.
2. Set the function switch to “
” range.
3. Press the “Select” Button to select continuity measurement mode, and the symbol “
”
will appear on the display.
4. Connect the test leads across the load to be measured.
5. If the circuit resistance is lower than about
30Ω,
the built-in buzzer will sound.
