Operating manual for the TG basic 1 appliance tester
Gilgen, Müller & Weigert
9.1.2. Measuring the insulation resistance
The insulation resistance is measured automatically. Switching to
permanent measurement is not possible.
Failure to reach the limit value is indicated as follows:
- The momentary measurement value blinks
- An audio signal is emitted
When performing the protective conductor resistance
measurement, the automatic test sequence can also be switched
to a permanent measurement (max. 3 min).
When the tester is in the normal measuring mode, pressing the
„START“ button switches the tester into the permanent
measurement mode.
The bar graph is then no longer shown in the display.
Pressing the button again continues the measurement with a
reversed test current polarity. Pressing the button again ends the
protective current measurement and continues with the next
measurement in the measuring sequence.
During permanent measurement, the connecting cable of the test
object should be moved, section by section, along its whole
length, in order to find broken conductors or weak points. The
momentary measurement values are continuously acquired and
displayed by the tester. The maximum measurement value is
stored and displayed in the assessment window at the end of the
measuring sequence.
