6 GMC-I Messtechnik GmbH
2 Applications
The tester is intended for the testing and measurement of repaired or modified electrical
devices in accordance with DIN VDE 0701-702. These regulations require the measurement
of protective conductor resistance, insulation resistance and equivalent leakage current for
repaired or modified electrical devices, as well as testing for the absence of voltage at
exposed, conductive parts for data processing systems and office machines.
Testing for the absence of voltage at the mains connection protective conductor and line volt-
age measurements can also be performed with this instrument. The device under test can be
connected to mains power at the mains outlet integrated into the tester, which provides for
the measurement of power consumption and the testing of functions.
Note!
Limit values displayed at the instrument make reference to periodic testing require-
ments set forth in VDE 0702: 1995.
3 Operating and Display Elements
(1) Mains Plug
The tester is connected to the 230 V mains outlet with the mains plug. If no earthing contact
socket is available, or if only three-phase current is available, the KS13 cable set can be used
to establish a connection.
The mains connection must be fused. Maximum nominal rating: 16 A!
(2) PE Signal Lamp for Protective Conductor Testing
The PE signal lamp lights up, if a potential difference of ≥ 100 V occurs
between the contacting surface (4) and the earthing contact at the mains plug (1).
(3) Alligator clip (gripper clip for attachment to the test probe)
Connect the housing of the device under test with the alligator clip for measurement of pro-
tective conductor resistance.
(4) Contacting Surface for Contact Finger
The PE signal lamp (2) lights up, if a potential difference of ≥ 100 V occurs between the PE
protective conductor at the mains plug (1) and the contacting surface.
The contacting surface is electrically isolated from all terminals, as well as from the measuring
circuit, and thus conforms to protection class II!
(5) Measuring Function selector Switch
Measuring functions can be selected with the measuring function selector switch. Displayed
values at intermediate switch positions have no significance.
(6) Connector Jack/Terminal for Measurement of Contact Current at Conductive
Components at the Device Under Test
This terminal is intended for the measurement of contact current at exposed conductive parts
which are not connected to the protective conductor.
(7) Mains Outlet
The DUT can be connected to the integrated mains outlet for the measurement of power
consumption and functions testing.
Residual current measurement is performed in this way as well.
Overcurrent protection is provided by the mains fuse or circuit breaker, see (1).
