Characteristics and range for use:
1. Detection: U > 127V AC
2. Frequency: 50...60Hz ± 5%
Continuity Test
Always perform an autotest before and after using the tester; never use the tester if the
autotest proves that the tester is faulty.
Before performing a continuity test, disconnect all power to the circuit to be tested and
discharge all capacitors thoroughly.
1. Connect the red test probe to the " + " jack and the black test lead to the "CoM" jack.
2. Connect the two test probes across the circuit to be tested.
3. If one led at least turns on, stop the test and do not proceed because the circuit is live.
4. Press the continuity test key.
5. If the 12V and 24V green leds, the 50V led, the "
buzzer sounds continuously, the circuit has continuity.
6 If accidentally you press the continuity test key to perform continuity test on a live
circuit, the buzzer will sound continuously and the 127V led will light up when the circuit's
voltage is more than 50V ac.
phase rotation Test
Always perform an autotest before and after using the tester; never use the tester if the
autotest proves that the tester is faulty.
Before phase rotation test, verify the presence of voltage on the three phases to be tested
on a three-phase system.
1. Connect the red test probe to the " + " jack and the black test lead to the "CoM" jack.
2. Connect the red test probe to the first phase and the black test probe to the second phase.
3. Press the phase rotation test key.
4. If the L1-to-L2 green led lights up, the phase rotation order is clockwise. If the L1-to-L3
red led lights up, the phase rotation order is anticlockwise.
note: The voltage detection function remains active during this test.
Characteristics and range for use:
1. Voltage: 360V < U < 690V
2. Frequency: 50Hz and 60Hz (± 5%)
30ma differential Circuit-breaker Tripping (rCds) Test
attention:
This test involves creating a fault current (> 30mA at 230VAC) between
the phase and earth.
1. Connect the red test probe to the" + " jack and the black test lead to the "CoM"
jack.
2. Connect the red test probe to the phase and the black test probe to the earth
terminal bar. A voltage indication is displayed.
3. Press the RCD test key.
4. The 30mA differential circuit breaker must trip. After the circuit breaker trips, the
voltage indication disappears.
