test lead into the 10A jack.
4.15.2 Set the rotary selector to the A range position.
4.15.3 Press the "SELECT" button to switch to AC
measurement. Then press the “RANGE” button to
choose the auto range or manual range mode.
4.15.4 Connect the test leads to the circuit for measurement.
4.15.5 Take the reading on the main indicator of the LCD.
NOTE:
1) At the manual range mode, when only ‘OL’ or ‘-OL’ is
shown on the LCD, it means the measurement has
exceeded the range. A higher range should be
selected.
2) Under the manual range mode, when the scale of the
value to be measured is unknown beforehand, set the
range to the highest.
3) ” means the maximum current of the mA jack is
400mA and the maximum current of the 10A jack is
10A. At the 10A jack, current exceeding the limit will
blow the fuse.

4.16 MEASURING RESISTANCE
WARNING
Beware of Electrocution.
When measuring in-circuit resistance, make sure
that the power of the circuit under test has been
turned off and that all capacitors have been fully
discharged.
4.16.1 Plug the black test lead into the COM jack and the
red test lead into the Ω jack.
4.16.2 Set the rotary selector to the Ω range position.
4.16.3 Press the "SELECT" button to switch to Ω
measurement. Then press the “RANGE” button to
choose the auto range or manual range mode.
4.16.4 Connect the test leads to the ends of the resistor or
circuit for measurement.
4.16.5 Take the reading on the main indicator of the LCD.
NOTE:
1) At the manual range mode, when only ‘OL’ or ‘-OL’ is
shown on the LCD, it means the measurement has
exceeded the range. A higher range should be
selected.
2) When the input is open, ‘OL’ will appear on the LCD to
indicate that the range has been exceeded.
3) For measuring resistance above 1MΩ, it may take a
few seconds to get a steady reading. This is normal
for high resistance reading.
