6.2 Compensation of the measuring line
In order to achieve correct results when measuring the protective conductor
resistance, the resistance of the measuring line must be compensated (zero
balance).
Press the fuction button [Comp.] (Fig. 5).
The zero balance menu appears. Follow the instructions in the display
(Fig. 6):
Fig. 6
– Connect the test tip/test
clip with the measuring line
and insert the measuring
line plug in the ‚Probe’
socket (Fig. 1).
– Connect the test tip/test
clip with the protective
earthing contact of the test
socket.
If the following message appears in the display:
‚Fault: zero balance’
and a permanent warning signal sounds, the measuring line resistance is
greater than 2 Ω and cannot be compensated.
The protective conductor resistance test is locked.
In this case the measuring line should be checked or be replaced with a
low-impedance version.
If the measuring line has been successfully compensated – the following
message appears in the display
‚Zero balance OK’.
Press the [Next] button, only then disconnect the line!
6.3 Setting the measurement method for protective conductor
current measurement (also current touch measurement)
In the case of devices of protection class I, on which the insulation
resistance measurement cannot or may not be carried out, the protective
conductor current measurement is an alternative measurement for
determining the insulating capacity.
The protective conductor current can be determined either by the direct
measuring method, the differential current method or the substitute leakage
current method.
The direct measuring method or the differential current method should be
used with test objects that can only be switched on with mains voltage
(also see Point 9.8).
Caution! In this case the test object is supplied with mains
voltage during the test.
The differential current measurement determines the total leakage current of
the test object by measuring the total current of all avtive conductors (L-N).
The differential current measurement must be applied if the test object has
additional earthing connections or cannot be insulated.
Direct measurement can be applied if the test object has no additional
earthing connections or can be insulated.
In order to change the measuring method, press the [Measure] function
button in the configuration menu, see Fig. 5.
The symbol in the headline changes accordingly:
[DIR.] – direct measurement
[DIF.] – differential current method

8. Conducting tests:
Explanation of terminology
8.1 Touch current (IT)
Current that can flow to earth via the person handling the device (test
object).
The measurement is carried out between touchable conductive parts of the
test object and the earth.
The measurement can either be made directly or with the differential current
method.
Direct measurement is applicable if the test object can be insulated from
earth.
In all other cases the differential current method should be used.
The touch current measurement is carried out on test objects in protection
class II with touchable conductive parts, or on test objects in protection
class I, which have touchable conductive parts that are not connected to the
protective conductor.
The measurement is to be carried out in both positions of the mains
&&
&
&&
plug - the reversal of polarity is automatic with the tester extracting and reversing the mains plug is not necessary.
Also see measuring principle circuits on Page 19.
&&
&
&&
8.2 Differential current (ID)
In terms of the standards DIN VDE 0701/0702, this is the total instantaneous
values of all currents flowing through all active conductors on the mains
side connection of the device (test object).
The differential current method is a measuring method for determining
protective conductor current or touch current.
The total leakage current of a test object can be measured. This measuring
method must be applied if the test object cannot be insulated.
Also see measuring principle circuit M6 on Page 18.
&&
&
&&
Caution! The test object is supplied with mains voltage
during the test.
8.3 Substitute leakage current (I
Current that would flow through the interconnected active conductors of the
device (test object) and the protective conductor or the touchable conductive
parts at nominal voltage and nominal frequency of the device.
This measuring method determines the leakage current without mains
voltage. It is an alternative measuring method for determining protective
conductor current or touch current.
Also see measuring principle circuit M4a on Page 18.

8.4 Insulation resistance (R
Ohmic resistance between the conductive parts separated by insulation.
Measurements are taken between the active parts and the body as well as
touchable conductive parts that are not connected to the protective
conductor.
Also see measuring principle circuits on Page 17.
&&
&
&&
)
INS
8.5 Protection class I (PC I)
The active parts of the device are protected against direct touching by the
basic insulation. Through connection of the touchable conductive housing
parts to the protective conductor, these are included in the protective action
in the case of indirect touching (fault protection) with the system. The
device has a protective conductor connection (earthed plug).
8.6 Protection class II (PC II)
The active parts are separated by strengthened or double insulation (basic
insulation and additional insulation). This ensures protection against direct
contact.
Protection against indirect contact is also given, since an insulation fault is
practically impossible. Such devices can nevertheless have touchable
metallic housing parts. Devices of protection class II have a mains plug
without an earthing contact.
8.7 Protection class III (PC III)
Devices of protection class III are exclusively connected to protective extralow voltage electric circuits.
The protection against dangerous body currents is achieved by the low
voltage and the safe separation to other electric circuits.

Operating manual for the TG uni 1 appliance tester
Explanation of terminology
8.8 Protective conductor current (IPE)
Current that flows through the protective conductor from the devices (test
objects) of protection class I, when their bodies are insulated from earth.
A direct measurement is applicable if the test object can be insulated from
earth.
In all other cases the differential current method should be applied, see Point
6.3 (Basic settings of the tester, Page 10).
Also see measuring principle circuits on Page 18.
&&
&
&&
Caution! The test object is supplied with mains voltage
during the test.
8.9 Protective conductor resistance (RPE)
Resistance between any conductive touchable parts, connected to the
protective conductor for protective purposes, and the earthed contact of the
mains plug, the device plug or the protective conductor, which is constantly
connected to the mains power supply.
During the measurement of the protective conductor resistance, the
connecting cable should be moved, section by section, along its whole
length. This measuring method only applies for devices of protection class I.
Also see measuring principle circuit M1 on Page 17.
&&
&
&&
8.10 Visual inspection
Testing in accordance with DIN VDE 0701 or 0702 also involves visual
inspection of the device.
According to the standard the devices should be inspected for external
defects (without opening the device) and, as far as possible, for suitability to
the place of installation. In particular, attention should be paid to the
following:
– Damage to the housing
– Defects of the cord connector guard and strain relief fittings
– External damage of the connecting cables
– Unauthorised interference and changes
– Signs of overloading and improper use

12.1 Visual inspection
The [->Next] button takes you to the first stage of the test, the visual
inspection (Fig. 54).
The housing, connecting cable, inscriptions and other parts should be
inspected in this test.
You confirm positive results of the visual inspection by pressing the
appropriate buttons – the display changes from ‘not OK’ to ‘OK’ (Fig. 55).

12.2 Insulation resistance
The limit value is:
0.25 MΩ (PC III)
After pressing the [->Next] button, the display for the insulation resistance
measurement appears (Fig. 56).
Beside the measured value, the level of the test voltage is also displayed
(min. 500 V DC).
The star sign on the left side of the display blinks when the
&&
&
&&
measuring process is running (the values are being measured).
The [OK] button appears when the measured value is determined.
A help display with a measuring principle circuit and a help text is also
available here.
Since the tester cannot provide the specific low voltage for the test
&&
&
&&
object, a function test is not carried out for test objects in PC III.
Alternatively, the test object can be tested according to PC II with
the appropriate power supply unit - see Point 11 on Page 29.
