To test for continuity:
(1) Discharge totally the tested circuits and keep them completely separated from the
power supply before test.
(2) Insert red lead or specific TEST-marked test lead into red input terminal and black
test lead to black terminal.
(3) Connect red and black alligators or test probes to the circuit under test.
(4) Turn the rotary switch to Ω position, then press TEST button to begin. Refer to
Figure 3 for details.
F1: Long press F1 for about 2 seconds to turn on/off the backlight; short press to turn
on/off 20 Ω compare function and LCD will show buzzer indicator, the buzzer will
alarm if the measured resistance is ＜20Ω.
F2: Press to turn on/off TEST LOCKED function. When it is necessary to take a long
-time measurement, press F2 to enable the function, lock indicator shows on LCD,
you then just need to press TEST down once, release it and the Tester will take
measurements continuously.
Press TEST again to stop the measurements. To disable the function, press F2 again
or turn the rotary switch to other functions.
F3: Press to zero the test leads. First short-circuit two test leads, and then long press
F3 to reset the display to 0.00Ω, “ZERO” will show on LCD, indicating the operation
completes.
Caution:
● To ensure an accurate test, please perform the zeroing before test

test lead to black terminal.
(3) Connect red and black alligators or test probes to the circuit under test.
(4) Turn the rotary switch to “Insulation” position and select proper test voltage, then
press TEST button to start.
Caution
● Make sure the test circuits are de-energized before measurement. Do not measure
any live electrical devices or lines.
● Before the test starts, the Tester will automatically display the voltage between two
input terminals if this voltage is 30V, and TEST button will be inhibited. ＞
