tween two measurements.
Measurement of AC voltage (
V
)
Connect the red probe cable to the
VΩ Hz
mAμA
socket,
and the black one to the “COM” socket.
Set the dial to the AC voltage position. Connect the
measurement probes to the circuit to be measured.
Note: The reading can be unstable, especially in the
200 mV measurement range, if the probe cable is not
connected to the circuit being measured.

Diode and interruption testing
Diode testing: Connect the red probe cable to the
VΩ Hz
mAμA
socket, and the black one to the “COM” socket
(the red probe is for “+” polarity). Set the dial to the
position. Use the “FUNC” pushbutton to set the
diode testing (
) function. Connect the red probe
cable to diode’s anode, and the black one to its cath
-
ode. The display will show the diode’s approximate
forward voltage. If the connection is reversed, “OL”
will appear in the display. Interruption testing:
Con-
nect the red probe cable to the
VΩ Hz
mAμA
socket, and
the black one to the “COM” socket. Set the dial to the
position. Use the “FUNC” pushbutton to set the
interruption testing (
) function. Connect the mea
-
surement probe to the circuit to be tested. If the circuit
is connected to a power source, switch of the power
source and discharge the capacitors before starting
measurement. Short-circuits (less than 100 Ω) will be
indicated by the built-in buzzer.
