Multifunction Installation Tester/English
: Low Battery
: Indicates high temperature and therefore cannot make any measurements
Message:
Half: Appears during the auto test when rcd has operated on the x ½ test
Half Trip: Appears during the manual test when rcd has operated on the x ½ test
UL OVER: Appears when UF voltage exceeds the previously set UL voltage. (UL voltage can be set to 25V or
50V) The user must check the impedance between L-PE
5.1.4-Displayed icons (symbols) and messages when using the LOW OHM and CONTINUITY functions
Symbol:
: Indicates correct input terminal connectivity. The user should connectthe test leads to the
appropriate terminals indicated by color coding.
: Low Battery (The icon will be flashing along with the beep sound).
: The resistance of the test leads are included in the test measurement
: The resistance of the test leads are not included in the test measurement
5.1.5-Displayed icons (symbols) and messages when using the RE functions
: Indicates correct input terminal connectivity. The user should connect the test leads to
the appropriate terminals indicated by color coding.
: Low Battery (The icon will be flashing along with the beep sound).
: The resistance of the test leads are included in the test measurement
: The resistance of the test leads are not included in the test measurement
5.1.6-Displayed icons(symbols) and messages in INSULATION function
: Indicates correct input terminal connectivity. The user should connect the test leads to
the appropriate terminals indicated by color coding.
: Low Battery (The icon will be flashing along with the beep sound).
: Indicates high voltage (125V, 250V,500V or 1000V) at probe terminals, Use caution
5.2-Using the LOOP/PFC Function
1-Before you do a loop impedance test, use the zero adapter to zero the test leads or the mains cord. Press
and hold F4 button for more than two seconds until the
the lead resistance, stores the reading in memory, and subtracts it from readings. The resistance value is
saved even when the power is turned off so it is unnecessary to repeat the operation each time you use the
tester with the same test leads or mains cord.
Note: Be sure the batteries are in good charge condition before you zero the test leads.
2-You can select UL Voltage by Pressing and hold F3 button for more than two seconds (25V or 50V).

5.2.1-Using the No Trip LOOP Measurement to be selected where the circuit is protected by an RCD whose
rating is 30mA or above
1-Turn the rotary switch to the LOOP/PFC position
2-Connect the test leads as Figure Figure 4
3-If voltage of the L- PE on the lower left appears, the
unit is ready to TEST
4-Press the TEST button when ready
5-If NOISE appears during the No Trip Loop
Measurement, the displayed value may not be
accurate due to "mains" interference and the
test should be repeated
When carrying out the test from a 13A socket
the points of contact are automatically selected by
the plug top connection
