● This Tester is only applicable for single-phase 230V(±10%)/50Hz
mains supply.
● Do not touch any exposed conductor during test.
● You can touch tested conductor only under a totally safe conditions
during test.
● Remove the test leads immediately from the power supply after test.
●Do not keep test leads connected onto the power for a long time.
● Never open the Tester’s casing during test, for hazardous voltage may
be present inside. If any fault happens, please have the Tester serviced
by professional personnel.
● If the Tester works abnormally(e.g. incomplete display, unexpected value,
damaged casing, noise during test indication), please send it to professional
staff for repair before using the Tester.
● Do not use the Tester if the operator’s hands are wet.
● For the sake of your safety, use only the certified test leads supplied by
our company, prohibit replacing by any other test leads during test.
● Do not expose the Tester to any sunshine, extreme temperature/humid
-ity environments.
● Clean the Tester with soft dampened cloth or mild detergent. Do not use
any abrasives or corrosives.
● Dry the Tester before storing it if it is wet.
( )
● Adopts intelligent micro-controller chip to maintain high accuracy, high
reliability and stability.
● Wiring Check:
LCD Indication Connection Status
L-N&L-PE flash abnormal power supply or no
supply to tested circuits
L-PE&N-PE flash, L-N doesn’t flash the tested terminals are badly or
not earthed.
L-N&N-PE flash, L-PE doesn’t flash neutral terminal is open
L-N,L-PE and N-PE flash wrong wiring to tested terminals,
the Tester will prohibit the tests regarding the above status, except reverse
connection between earth and neutral terminals,
●Phase Angle Selection: The tests can be performed at positive 0 or
negative 180 phase angle.
●Test Locked: The Tester will automatically carry out the tests once the
test leads are connected to the tested terminals (UT585 Only)
●Auto Ramp: Measure trip current and trip time simultaneously.
●Overload Indication: Display “＞300ms” or “＞1000ms” when trip time
exceeds Max. test time.
● Data Hold: The readings will be frozen when the test finishes.
●1A Large-Current Trip Test(UT585 Only)
●Overheat Check: When internal components inside the Tester is
overheated, LCD will display , and the Tester will automatically
prohibit the tests. After it is cooled down, displays and the tests can
restart.
●Backlight: Press LIGHT button to turn on/off the backlight.
●Low Battery Indication: When battery voltage is＜7V, shows,
please replace the battery timely.
●Auto Power Off: The Tester will automatically power off after ten minutes'
idling. To disable the function, press and hold 0 / 180 button while
turning on the instrument.

(1)Test Lead Connections
Connect three connectors of the test lead respectively to three input terminals
of the Tester: Red—L, Green—E, Blue—N, then connect another terminal of
the test lead to tested circuit (230V/50Hz power socket).
(2)Voltage Test
Set the rotary switch to V position, The tester now can measure the voltage
between L and N terminals, which should fall within 207V-253V, if not, please
check if the wiring is correct before proceeding into next step. Besides, DC
voltage test is available in Model UT585, when DC voltage test is needed
during other measurements, connect test leads into L and N input terminals
to begin the test.
(3)Wiring Check
Turn the rotary switch to RCD ranges and check the wiring status indicated
on LCD.
LCD Indication Connection Status
L-N&L-PE flash abnormal power supply or no supply
to tested circuits
L-PE&N-PE flash, L-N doesn’t flash the tested terminals are badly or not
earthed.
L-N&N-PE flash, L-PE doesn’t flash neutral terminal is open
L-N, L-PE and N-PE flash wrong wiring to tested terminals,
the Tester will prohibit the tests regarding the above status, please check
the wiring and correct the connection before restart the tests.
(4) Press I△n Up or DOWN button to adjust the trip current (I△n) the same
as the rated trip current marked on RCD.
Default value: I△n 30mA 0
(5) Test
5.1 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
●Fast Tripping ×2: Max. trip time up to 1000ms
●Fast Tripping ×5: Max. trip time up to 300ms
●AUTO RAMP Test: 20%~110% of rated trip current(I△n), Max. trip time up
to 300ms.
5.2 Press TEST button
●Non-Tripping ×1/2-----The RCD should not trip.
●Tripping ×1: ---------The RCD should trip.
●Fast Tripping ×2:-------- The RCD should trip.
●Fast Tripping ×5:---------- The RCD should trip.
●AUTO Ramp Test: --------The RCD should trip, and trip time and trip current
are displayed simultaneously.
5.3 Press 0 /180 button to set the phase angle and repeat Step 5.1 to
determine the fastest trip time.
5.4 Press to change the phase angle and repeat Step 5.1
5.5 When the tests finish, disconnect the test lead from the tested circuit
immediately.
Danger :Do not touch any exposed earthing metal or conductor during
the operation
(6)Test locked: To enable the test locked function, press and hold TEST
button while turning on the Tester. Then connect the test lead to tested
terminals, the tests can be automatically performed (for UT585 Only)
(7) Backlight: when testing on dimly lighted sites, press LIGHT to turn
on /off the backlight.
(8) Auto Power Off: To disable the function, press and hold 0 / 180
button while turning on the Tester, LCD will show “APO OFF” icon; the Tester
usually defaults at APO ON status(no pressing 0 / 180 button).
VI. Maintenance and Repair
