Operating manual for the TG basic 1 appliance tester
Gilgen, Müller & Weigert

At the start of measuring, the tester checks to see if the
measuring current is greater than 200 mA. If this is not the case,
the test is aborted.
This can occur for the following reasons:
- The test object is not of protection class I
- The test object is not connected to the tester or the test
line is not connected
- The protective conductor has an open-circuit
This is indicated by a scrolling message in the status line.
The tester performs the following checks:
a) Check of the test wiring!
The measurement procedure is continued when the
missing connection to the test line or test object is
restored and the measuring current is > 200 mA.
b) Check that the appliance conforms to
protection class I!
If the tester detects that the appliance does not
conform to protection class I, then the test must be
aborted by pressing the „START“ button.
If the test wiring is „OK“ and the test object conforms to protection
class I, then the protective conductor connection has an open-
circuit or high resistance. The test must be aborted by pressing
the „START“ button.
When the test is aborted, the assessment window is shown in the
display.
Measurement of the insulation resistance and substitute leakage
current is not performed.
This also applies when the measured protective conductor
resistance is > 1
