RESISTANCE, AUDIBLE CONTINUITY, DIODE and CAPACITY TEST
Connect the red test lead to the "V Ω °C/°F" jack
[10]
and the black lead
to the "COM" jack
[9]
.
Set the rotary switch
[3]
in the "
" position.
For resistance test and continuity test, press the mode button
[5]
until
the “Ω” symbol appears in the display. Connect the test leads to the
resistor to be measured and read the value in the LCD display.
Disconnect one side of the device under test to avoid interference from
the rest of the circuit. When the resistance is <100Ω, a continuity buzzer
will sound.
For diode measurements, press the mode button
[5]
until the "
"
symbol appears in the display. When the diode passes the test, indicated
forward voltage will be 0.4~0.7V while reverse voltage will indicate “OL”.
When the diode is short circuited, both readings will be ±0mV; when
open, both measurements will shown “OL”.
Notes:
forward DC current: ±0.3mA
open circuit voltage: ±1.5V
For capacity measurements, press the mode button
[5]
until “F” is shown
in the display.
Warning
: disconnect power to the device under test
(including batteries!) and discharge all capacitors before measuring
capacitance. Connect the test leads to the capacitor to be measured and
read the value in the LCD display.
FREQUENCY or % DUTY CYCLE measurement
Connect the red test lead to the "V Ω °C/°F" jack
[10]
and the black lead
to the "COM" jack
[9]
.
Set the rotary switch
[3]
in the "Hz·%" position. Select Hz or % duty with
the Hz - % select button
[6]
,
the selection is indicated in the display.
Connect the test leads to the circuit under test and read the value in the
LCD display.
TEMPERATURE
Set the rotary switch
[3]
in the "°C·°F" position. Select °C or °F with the
mode select button
[5]
,
the selection is indicated in the display.
Insert the side of the temperature probe adapter marked with “+” in the
"V Ω °C/°F" jack
[10]
and the other side (“-”) in the "COM" jack
[9]
.
Hold the probe head to the device under test for ±30s and read the value
in the LCD display.
Do not
change the rotary function switch when the thermocouple is
connected to the meter.

Battery
When the low battery indication appears, replace the internal battery.
