Measurement Operation
l
Make s ure the Sleep Mode is not on if y ou f ound there is no display on the LCD af ter turning on the Meter.
l
Make sure the Low Battery Display is
not on, otherwise f alse readings m ay be prov ided.

A. DC Voltage Measurement
Warning – To avoid har ms to you or damages to the Meter fro m electric shock, pl ease do not attemp t to
measure voltag es high er th an 1000V or 750V r ms although r eadings may be obtained.
Take extra attention wh en measuring high vol tag es to avoid electric shock.
To measure DC v oltage, connect the Meter as f ollows:
7. Insert the red test lead into t he
V
Ω
input terminal and t he black test lead int o the
C OM
input terminal.
8. Set the rot ary switch to an appropriate measurem ent position in
V
range.
9. Connect the test leads across with the object being measured.

Note
l
If the v alue of v oltage to be meas ured is unknown, us e the m axim um measurement position (1000V) and reduce
the range step by step until a satisfactory reading is obtained.
l
The LCD display s “1” indicating the existing s elect ed range is ov erloaded, it is required to select a higher range in
order to obt ain a correct reading.
l
In each range, t he Meter has an input im pedance of approx. 10M
Ω
. This loading eff ect can c ause measurement
errors in high im pedanc e circ uits. If the circuit impedance is less t han or equal to 10k
Ω
, the error is negligible
(0.1% or less ).
l
When DC v oltage m eas urement has been c omplet ed, disconnect the connection bet ween the testing leads and
the circ uit under test.
