Voltage measurement DC and AC
(see fig 1)
1.
Insert the red test lead into the V
Ω
mA terminal and the black test
lead into the COM terminal.
2.
Set the rotary switch to an appropriate measurement position in
V--range for DC or V~ for AC. When the value is unknown
always start from the max range 500 V.
3.
Connect the test leads across with the object being measure.The
measured value shows on the display.
Note
•
Displays 1 selected range is overload; it is required to select a
higher range in order to obtain a correct reading.
•
In each range, the Meter has an input impedance of approx.
10M
Ω
. This loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than or equal
to 10k
Ω
, the error is negligible (0.1% or less).
DC Current Measurement
(see fig 2).
Warning
Never attempt an in-circuit current measurement where the voltage
between terminals and ground is greater than 60V.
If the fuse burns out during measurement, the Meter may be dama-
ged or the operator himself may be hurt. Use proper terminals, func-
tion, and range for the measurement.
When the testing leads are connect-ed to the current terminals, do
not parallel them across any circuit.
To measure current, connect as follows:
1.
Turn off power to the circuit. Discharge all high-voltage capacitors.
2.
Insert the red test lead into the 10A or V
Ω
mA terminal and the
black test lead into the COM terminal.
3
. Set the rotary switch to an appropriate measurement position in
A
...
range. When the value is unknown always start from the
max range 10 A.
