OPERATING INSTRUCTIONS
VOLTAGE MEASUREMENT
1. Connect red test lead to “VΩ” jack, black lead to “COM” jack.
2. Set RANGE switch to desired VOLTAGE position, if the voltage
to be measured is not known beforehand, set switch to the
highest range and reduce it until satisfactory reading is
obtained.
3. Connect test leads to device or circuit being measured.
4. Turn on power of the device or circuit being measured voltage
value will appear on Digital Display along with the voltage
polarity.
Please note:

In small range, the meter may display an unstable reading
when the test leads have not been connected to the load to be
measured. It is normal and will not affect the measurements.

When the meter shows the over range symbol “1”, a higher
range must to be selected.

To avoid damage to the meter, don’t measure a voltage which
exceeds 600Vdc (for DC voltage measurement) or 600Vac (for
AC voltage measurement).
CURRENT MEASUREMENT
1. For reading less than 200mA connect red lead to “mA” and
black lead to “COM” (for measurements between 200mA and
10A, connect red lead to “10A”) ensure jacks are fully
depressed.
