6. OPERATION INSTRUCTION
6.1. MEASURING VOLTAGE
1) Connect the BLACK test lead to the "COM" jack and the RED to the "VΩ" jack.
2) Set the function switch to desired V
3) If the voltage magnitude to be measured is unknown beforehand, select the highest range.
4) Connect the test leads across the source or load to be measured.
5) Read LCD display. The polarity of the RED lead connection will be indicated when making a DC measurement.
Note:
a. In small range, the meter may display an unstable reading when the test leads have not been connected to the load to be measu-
red. It is normal and will not affect the measurements.
b. When the meter shows the over range symbol "1", a higher range must to be selected.
c. To avoid damage to the meter, don't measure a voltage which exceeds 1000Vdc (for DC voltage measurement) or 750Vac (for AC
voltage measurement).
