** END **
(1) Test Lead Connections
Insert three connectors of test leads respectively into three termi
-nals of the Tester: Red to L, Green to E, Blue to N, and then
connect another end of test leads to tested circuit (power socket
230V/50Hz).
Danger
● Do not touch any exposed metal or conductor during these
test operations.
● Relative components in the Tester may get hot during the
operation, if the Tester continues to work for a long time, it
may cause damage to the unit or other hazards. Therefore
the Tester is recommended not to use for a long-time and
continuous tests on production lines in RCD factories .It is
only suitable for sampling precision tests.
● The time interval between each test with trip current 300mA
/500mA(large current trip test) should be ensured up to 5
minutes.
6.1 Cleaning the Casing:
Clean the surface of the Tester with dry soft cloth; No alcoholic and
solvent is allowed, for it may cause corrosive damage to the LCD;
Protect the Tester from any moisture.
6.2 Repair
Please contact our after-sale service center or agents if following
issues happen:
A. The Tester casing is broken or the components are damaged;
B. LCD display works abnormally;
C. Unexpected data occur under normal use;
D. The buttons don’t function normally;
E. Noise happen during tests.
(4) Taking RCD Tests
4.1 Set the rotary switch to test parameters
● Non-Tripping -------------------×1/2: Max. trip time up to 1000ms;
● Tripping -------------------------×1: Max. trip time up to 1000ms (Except
500mA);
● Tripping -------------------------×1(500mA): Max. trip time up to 300ms ;
● Fast Tripping------------------- ×5( only 10, 20, 30mA ): Max. trip time
up to 1000ms;
● Fast Tripping--------------------250mA: Max. trip time up to 40ms (for
UT581 only);
● AUTO RAMP Test: for UT582 only, 20%~110% of rated trip current
(I
△
n), Max. trip time up to 300ms.
4.2 Press TEST button
● Non-Tripping Test -------The RCD should not trip.
● Tripping --------------------The RCD should trip.
● ×5 Fast Tripping: ----------- The RCD should trip.
● 250mA Fast Tripping: -------The RCD should trip (for UT581 only).
● AUTO Ramp Test: ---------- The RCD should trip, and trip time and
trip current are displayed simultaneously (for UT582 only).
4.3 Press PHASE (0 /180 ) button to set the phase angle and repeat
4.2 to determine the fastest trip time.
4.4 Press to change the phase angle and repeat 4.2
4.5 When the tests finish, disconnect the test lead from the tested
circuit immediately.
(2) Wiring Check
Check the wiring status by identifying three LEDs. If P-E and P-N
green LEDs are on and red LED is off, it indicates the wiring is
correct, otherwise wiring is wrong due to reverse connection
between L and N terminals or bad grounding. Please unplug the
test leads, check and correct the relative circuits until right wiring
indication is obtained.
(3)
Press I
△
n button to adjust the trip current(I
△
n) the same as the
rated trip current marked on RCD. The set trip current will show
on lower part of LCD.
Default value: I
△
n----------------- 30mA
0 /180 ----------- 0
Caution:
Reverse connection between L and N terminals during
wiring check may cause RCD to trip, so please check and correct
the circuits until the wiring indication is obtained and before you
proceed into next operation.
Danger
Do not proceed into next operation (press TEST button) if the
wiring is incorrect, otherwise it may cause error to the result or
other hazards.
