OPERATION
Measuring DC/AC Voltage
•
The DC voltage ranges are 400mV, 4V, 40V, 400V and 600V.
•
The AC voltage ranges are 4V, 40V, 400V and 600V.
•
To measure DC/AC voltage, perform the following steps:
1.
Insert the red test lead into the Hz Duty%
terminal and the black
test lead into the
COM
terminal.
2. Turn the range selector to
and DC measurement mode and auto
range are set as default. To measure
AC voltage press
SELECT
switch to AC
measurement mode, and press
REL
to switch to manual range measurement
mode.
3. Connect the test probes with the object
being measured. The measured value
shows on the display.
Note:
•
When a measurement has been completed,
disconnect the test probes from the circuit
under test, and remove the test leads from the
input terminals.
Measuring Resistance
•
The resistance ranges are 400Ω, 4kΩ, 40kΩ, 400kΩ, 4MΩ and 40MΩ.
•
To measure the resistance, perform the following steps:
1.
Insert the red test lead into the Hz Duty%
terminal and the black
test lead into the COM terminal.
2.
Turn the range selector to Ω. Press REL
to switch from auto range as default to
manual range during the measurement if
required.
3. Connect the test probes with the object
being measured. The measured value
shows on the display.
Notes:
•
To obtain a more precise reading, you could
remove the object being measured from the
circuit when measuring.
•
When a measurement has been completed,
disconnect the test probes from the circuit under
test, and remove the test leads from the input
terminals.
