Operating manual for the TG uni 1, TG euro 1 and TG euro 1 med appliance tester
Conducting tests in accordance with VDE 0751-1, Example 6 - Testing removable cables
69
You can display the help screen by pressing the [help] button. A measuring
principle circuit corresponding to the figure in this operating manual and a
short help text are displayed. After pressing the [End] button you return to
the measuring display.
In the next stage the polarity of the test current (–) is reversed and the
protective conductor resistance is measured again.
During the measurement, the connecting cable should be moved,
section by section, along its whole length, in order to find broken
conductors or weak points.
The corresponding limit value „Lv“ and the momentary test current (+) are
also displayed.
18.3 Insulation resistance
After pressing the [OK] button the screen for insulation resistance
measurements is displayed (Fig. 135). The magnitude of the test voltage is
displayed as well as the measured value (minimum of 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 available here.
18.4 Documentation
After pressing the [OK] button, the display changes to the „Test result“
screen (Fig. 136).
Here you can see all the measurement results with the related limit values.
If the electrical values of all the measured results were ok, and the visual
inspection was also ok, then a message is displayed:
„Test OK“.
If the test was not successful the message says:
„Test not OK!“.
At this point you can cancel the test with the [cancel] button (the display
goes back to the „Appliance testing“ screen) or switch to the „Memory
menu“ with the [next] button.
In the „Memory menu“ (Fig. 137) you can confirm or modify the following
parameters: device ID number, device designation, name of the inspector,
date and customer number.
You can also change the storage location – from internal memory to MMC/
SD card and vice-versa.
The current setting is displayed via a symbol in the headline of the memory
menu.
