DC Voltage Measurement
1. Insert red probe to “INPUT” jack and insert black
probe to “COM” jack.
2. Place function measuring range switch to DC
voltage measuring range. Press “SEL” key, and
connect the probe to the power source or load to be
tested. The polarity of the end connected with red
probe will be shown in the display at the same time.
3. Read the measuring result from display.
Notes!
∆ If the range of voltage to be tested is not known in
advance, place function measuring switch to the
maximum range, then gradually reduce to obtain
the correct range.
∆ Pay special attention to avoid shock when
measuring high voltage.
