C-1 Measuring DC Voltage
1. Connect the black test lead to
COM
jack and
red test lead to
V
jack.
2. Set the rotary switch to
V
.
3. Connect the test leads across with the object
to be measured. LCD appears the measured
value and also the polarity of the red test leads.

Caution
1) If magnitude of the voltage is unknown, always
start with the highest range and reduce until
satisfactory reading is obtained.
2) If
1
is shown on the LCD, which means the
Meter is overloaded, then set the measuring
range to higher.
3)
means never exceed the maximum input
limit 1000V, otherwise internal circuit of the
Meter will be damaged.
4) Take extra care of voltage leakage when
measuring high voltage.
