5.1 Measurements at the Test Outlet(s)
Protective Conductor Resistance, R
SOCKET
PE
The probe must be plugged into the
PROBE PE/I
socket for the measurement of
C
protective conductor resistance. Measurement is performed between the protective
conductor terminal at the test outlet and the
PROBE PE/I
Protective Conductor Resistance, R
socket.
C
FIX
PE
This measurement is used for testing the
protective conductor at permanently connected devices. The test instrument must be
connected to the same supply circuit as the
device under test during measurement.
Good test results may be obtained
with parallel ground connections,
although the protective conductor is
interrupted.
The probe must be plugged into the
PROBE PE/IC socket for the measurement of
protective conductor resistance. Measurement is performed between the protective
conductor terminal at the mains connection
and the PROBE PE/I
socket.
C
Testing is performed up through a resistance
value of approximately 1.3 Ω with automatic
polarity reversal.
The earthing contact resistance and the test
current are indicated on the LCD (not for
MINITEST Base).
Checking the Zero Point and the Fuse
The zero point and the internal fuse can be
checked by inserting the plug attached to
the test probe cable into the PROBE R
ISO
socket and the tip of the test probe into the
PROBE PE/IC socket with the selector switch in
SOCKET or RPE FIX setting. The dis-
the R
PE
played value should not exceed 100 mΩ.Note: If a current of 0 mA is indicated, the
fuse is usually defective. Test and replace it,
if required.
It is absolutely essential to insert the
tip of the test probe into the
PROBE PE/IC socket for this test!
Use only the probe cable which is
included with the test instrument. If a
different probe cable is used:
– The measured value may be
distorted.
– The test instrument may be
damaged.
– Malfunctioning may occur.
Insulation Resistance, R
ISO
Various test types are provided for the measurement of insulation resistance.
The test type is selected automatically when
the test probe is plugged into the probe
connector socket (10).
The original test probe cable must be used
in order to take advantage of this function.
Test type switching cannot be assured if
other test probe cables are used.
• For safety class I DUTs without exposed
conductive parts:
Test insulation between L/N and PE at
the test outlet.
The test probe cable may not be plugged into
the PROBE R
socket for this test!
ISO
• For safety class II DUTs, or for safety
class I DUTs with exposed conductive
parts which are not connected to the
protective conductor:
Test between L/N at the test outlet and
the PROBE R
socket.
ISO
The test probe must be plugged into the
PROBE R
socket for this test!
ISO
The insulation resistance and the test voltage are indicated on the LCD (not for
MINITEST Base).
8GMC-I Messtechnik GmbH
Discharging the Device Under Test
Attention!
!
Note!
The device under test is automatically
discharged when the insulation test is
switched off (turn switch to R
or ID).
PE
The LEDs light up rapidly, one after the other
from left to right, during discharging.
Furthermore, residual voltage appears at the
display (not for MINITEST Base).
Leave the DUT connected to the test
instrument during the discharging sequence.
5.2 Measurements at the Mains Outlet(s)
Differential current and/or contact current
measurements are performed at the mains
outlet(s). The DUT must be unplugged, and
plugged back in again. In the case of mains
plugs which are not polarity protected, testing
must be conducted with the mains plug poled in
both directions.
The mains outlet(s) always conduct(s) voltage as soon as the test instrument has been switched on.
Make sure that the device under test
is switched off before plugging it into
the mains outlet.
The device under test must be switched on during
testing.
The device under test must be switched
back off before it is unplugged from the
mains outlet.
Differential Current Measurement, I
D
Total current from all phase conductors is
measured during differential current measurement. For safety class I devices, this
corresponds to the amount of current which
is conducted by the protective conductor.
Differential current is displayed in mA at the
LCD (not for MINITEST Base).
Evaluating the Measured Values
Measured values of less than 0.5 mA are
indicated by means of a green LED.
Measured values of greater than 3.5 mA are
indicated by means of a red LED. These
devices may be dangerous, however, for
example for 3-phase current devices, there may
be higher admissible limit values of e.g. 1 mA per
kW up to 10 mA, depending on the manufacturer’s specifications. These cases are all indicated with the red LED. Evaluation must be
conducted by a qualified electrician in this
case.
Measured values of between 0.5 and 3.5 mA
are indicated by means of a yellow LED. An
evaluation of electrical safety should be conducted by a qualified electrician in this case.
Contact Current Measurement, I
C
When measuring contact current, current is
measured which is conducted via the probe
at the PROBE PE/I
socket to the protective
C
conductor terminal at the device under test.
Evaluating the Measured Values
Measured values of less than 0.25 mA are
indicated by means of a green LED. There is
no danger in touching these parts.
Measured values of greater than 0.5 mA are
indicated by means of a red LED. Devices
which demonstrate these values are
dangerous because persons who touch
them are startled, which may result in
consequential accidents.
These devices may not be placed back into
service.
Measured values of between 0.25 and
0.5 mA are indicated by means of a yellow
LED. Current within this range is not
dangerous, but the threshold of perception
is approximately 0.1 mA depending upon
sensitivity, which causes mild tingling. This is
unpleasant for some people, for which
reason devices of this sort should be
examined.
Self-Test
A device self-test is conducted when the
selector switch is turned to the LED Test
position.
Testing is indicated by the LEDs which light
up one after the other from left to right.

8.1 Housing
No special maintenance is required for the
housing. Keep outside surfaces clean. Use a
slightly dampened cloth for cleaning. Avoid
the use of cleansers, abrasives or solvents.
8.2 Replacing the Fuse
Instructions on checking the zero point and
fuse are given in chapter 5.1.
Disconnect the instrument from the
measuring circuit before removing
the fuse for replacement!
Eliminate the cause of the overload after the
fuse has blown before putting the instrument
back into service!
The fuse holder is situated between the
mains power cable and the probe connector
socket. The characteristic value of the fuse is
indicated on the front plate or in chapter 7.
Please make absolutely sure that
only the specified fuse is inserted!
If fuses with other blowing characteristics, other current ratings or other
breaking capacities are used, the operator is placed in danger, and protective diodes, resistors and other
components may be damaged.
The use of mended fuses or short-circuiting
the fuse holder is prohibited.
The defective fuse can be disposed of with
the trash.
8.3 Recalibration
The respective measuring task and the
stress to which your measuring instrument is
subjected affect the ageing of the components and may result in deviations from the
guaranteed accuracy.
If high measuring accuracy is required and
the instrument is frequently used in field
applications, combined with transport stress
and great temperature fluctuations, we recommend a relatively short calibration interval
of 1 year. If your measuring instrument is
mainly used in the laboratory and indoors
without being exposed to any major climatic
or mechanical stress, a calibration interval of
2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory (DIN EN ISO/IEC 17025) the
deviations of your instrument in relation to
traceable standards are measured and documented. The deviations determined in the
process are used for correction of the readings during subsequent application.
We are pleased to perform DAkkS or factory
calibrations for you in our calibration laboratory. Please visit our website at
www.gossenmetrawatt.com (→ Company
→ DAkkS Calibration Center or → FAQs →
Calibration questions and answers).
