O p e rating Instructions
Testing AC/DC Voltage
1. Insert the black test lead into the “
COM
” jack and the red test
lead into the “
V
Ω
RPM
” jack.
2. Set the rotary switch in “
V
“ position, press the “ “ button to
select the “
AC/DC
” function according to symbol “
AC
” or “
DC
”
on the display
3. Connect the test leads to the circuit to be measured.
4. Read the reading on the display.
5. For DC voltage, the polarity of the red test lead will be displayed
as well as the value.
Testing AC/DC Current
1. Connect the black test lead to the “COM” jack, and the red test
lead to the “µAmA” jack
NOTE:
When the current to be measured is between 326 mA and 10A,
connect the red test lead to “10A” jack instead.
2. Set the rotary switch in “µA”, “mA” or “10A” position, press the
“ “ button to select the AC or DC function according to the
symbol “AC” or “DC” on display.
3. Connect the test leads in series with the load to be measured.
4. Read the reading on the display. For DC current, the polarity of
the red test lead will be displayed too.
Testing Resistance
1. Insert the black test lead into the “
COM
” jack and the red test
lead into the “
V
Ω
RPM
” jack.
2. Set the rotary switch in “ “ position. The polarity of the red test
lead is positive. The display shows “OL”, until connected to device
under test or when the circuit is open.
3. Connect the test leads across the load to be measured.
4. Read the reading on the display.
