MT-3109 AC/DC Digital Clamp Multimeter
Measurement Operation
A. DC/AC Voltage Measurement
(see figure 3)
Warning
To avoid harms to you or
damages to the Meter from
electric shock, do not attempt
to measure voltages higher
than 600V AC/DC, although
readings may be obtained
The DC Voltage ranges are: 400mV, 4V, 40V, 400V and 600V.
The AC Voltage ranges are: 4V, 40V, 400V and 600V.
To measure DC voltage, connect the Meter as follows:
(1) Insert the red test lead into the Hz Duty%
VΩ
terminal and the black test lead into the COM terminal.
(2) Set the rotary switch to . DC measurement mode and
auto ranging is a default.
(3) Press SELECT to switch to AC measurement mode or
press REL to switch to manual ranging measurement
mode.
(4) Connect the test leads across with the object being
measured. The measured value shows on the display.
Note
A. When DC/AC voltage
measurement has been completed,
disconnect the connection between
the testing leads and the circuit
under test and remove testing
leads from the input terminals.
B. Measuring Resistance (see figure
