Operating manual for the TG uni 1, TG euro 1 and TG euro 1 med appliance tester
Introduction

3. Safety instructions
The appliance tester was constructed and tested in accordance with the
applicable safety regulations and left the workshop in a faultless safety
condition. In order to maintain this condition and ensure safe operation, the
user must observe the instructions and warnings contained in this operating
manual.
With all work, the applicable accident prevention regulations of the
trade associations for electrical systems and equipment must be
observed.
To avoid electric shock, the applicable safety regulations and DIN-
VDE regulations regarding high touch voltage must be observed
without fail when working with voltages greater than 120 V DC or
50 V eff AC.
Measuring at a dangerous proximity to electrical systems should only be
carried out under the instruction of a responsible electrician, and never
alone.
Check the appliance tester and the connecting cables for external damage
before every new operation.
Make sure that the appliance tester and the cable connections are in
faultless condition. The appliance tester may not be used if one or more
functions fail or if functional readiness is not evident.
The measuring lines and the measuring accessories may only be
touched in the designated handling areas.
Touching measuring connections, e.g. test tips, must be avoided
under all circumstances.
If the safety of the operator is no longer guaranteed, the appliance
tester must be decommissioned and secured against unwanted
use. This is the case if the device:
– shows obvious signs of damage
– no longer carries out the required measurements
– has been stored under adverse conditions for too long
The appliance tester may only be used in the operating and measuring
ranges specified under Technical data.
Avoid subjecting the appliance tester to heating from direct sunshine. Only
this will guarantee faultless functioning and a long service life of the device.
Never open the housing of the appliance tester because of the danger of
high voltages. The appliance tester contains no parts that can be replaced
by the user.

Safety instructions

4. Appropriate usage
The tester may only be used under the conditions and for the purposes for
which it has been designed. It is particularly important to observe the safety
instructions and the technical data regarding ambient conditions and usage
in a dry environment.
The appliance tester may not be used for measuring in electrical systems.
The appliance tester may only be plugged into to a properly connected
earthed mains socket. This may be protected with a maximum 16 A!
The appliance tester is designed for operation with a rated voltage of 230 V
AC 50 Hz, it may never be connected to higher voltage.
The maximum output current of the mains socket is 16 A!
The appliance tester may not be used for constant measuring.
Operational safety is no longer guaranteed in the case of modifications or
conversions that have not been carried out by the manufacturer.
Maintenance or calibration work may only be carried out by the
manufacturer.
Subject the appliance tester to an electromagnetic field can impair the
function of the appliance tester.
In order to avoid damaging the appliance tester, the test socket and the
measuring connections may not be connected to an external voltage
source.
Only the supplied original measuring lines or equivalent safety measuring
accessories may be used!

6. Starting up
The appliance tester is equipped with modern touch-screen technology.
This means that the LC display and the control buttons are in one control
screen.
The control buttons are always edged.
After activating the mains switch a self-test is carried out.
If everything is in order, the following display appears on the touch-screen
as a switch-on message (Fig. 3):
Continue with button (Fig. 3).
The „Device settings“ screen appears (Fig. 3a).
6.1 Basic settings of the appliance tester

and a permanent warning signal sounds, the measuring line
resistance is greater than 2 Ωand 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 calibration OK.“ Press the [next] button, only then disconnect the line!
A symbol for successful compensation appears in the headline of the
configuration menu (Fig. 5):
6.3 Setting the measuring method – protective conductor current
measurement
In the case of devices of protection class I, where the insulation resistance
measurement cannot or may not be carried out, the protective conductor
current measurement is to be performed either directly or with the differential
current method. 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

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
calibration). Press the function button [comp.] (Fig. 5). The Zero
calibration menu appears. Follow the instructions in the display (Fig. 6):
–Connectthetesttip/test
clip with the measuring line and
insertthemeasuringlineplug inthe
„Probe“ socket (Fig. 1).
–Connect the test tip/test clip with

If the following message
appears in the display:
”Error: zero calibration”
Fig. 6
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 active conductors (L-N).
The differential current measurement must be applied if the test object
has additional earth connections or cannot be insulated. Direct
measurement can be used if the test object has no additional earth
connections or is insulated.
WARNING! The test object must be insulated in order to
correctly measure the protective conductor current.
To change the measuring method, press the [m. meth.] function button
in the configuration menu, see Fig 5.
The symbol in the headline changes accordingly:
[DIR.] – direct measurement [DIF.] – differential current method
Fig. 7 Once the date has
been set it remains
unchanged in the memory
of the appliance tester until
modified or deleted – the
appliance tester does not
have a real time clock!
6.4 Setting the date
You can set the test date on the appliance tester. Press the function
button [date] to change to the input screen (Fig. 5). The date is entered on
the touch-screen by means of the pictured 10-button keypad (Fig. 7). The
following formats are possible: |D.M.YY|, |DD.MM.YY| and |DD.MM.YYYY|.
The set date is saved along with the measuring results of every test and
also appears in the log printout.
