DIODE AND AUDIBLE CONTINUITY TEST
Range Description
Test
Condition
The approx. forward
voltage drop of the diode
will be displayed on the
LCD.
The forward DC current
is approx. 1mA, the
reversed DC voltage is
approx. 2.8V.
If the resistance of the
circuit under test is less
than 40
Ω
, the built-in
buzzer will sound.
Open circuit voltage is
approx. 2.8V.

OPERATING INSTRUCTION
DC VOLTAGE MEASUREMENT
1.
Connect the red test lead to the “V
Ω
” jack and the black test
lead to the “COM” jack
2.
Set the range switch to the desired “ ” range. If the voltage
to be measured is not known beforehand, set the range
switch to the highest range and then turn down range by
range until satisfactory resolution is obtained.
3.
Connect the test lead to the source or load to be measured.
4.
Read the voltage value displayed on the LCD.
AC VOLTAGE MEASUREMENT
1)
Connect the red test lead to the “V
Ω
” jack, and the black test
lead to the “COM” jack.
2)
Set the range switch to the desired “ ” range. If the
voltage to be measured is not known beforehand, set
the range switch to the highest range and then turn down
range by range until satisfactory resolution is obtained.
3)
Connect the test lead to the source or load to be measured.
4)
Read the voltage value displayed on the LCD.
