12.1 Visual inspection
The [next] button takes you to the first stage of the test, the visual
inspection (Fig. 73).
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. 74).
Please note: The visual inspection function is not present when the
appliance tester is in „Expert mode“!
For all subsequent tests, the test object must be switched on.
Pressing the [next] button brings the device to the Insulation resistance test
screen (Fig. 76).
12.2 Insulation resistance
The limit value is:
0.25 M
Ω
(PC III)
After pressing the [next] button, the display for the insulation resistance
measurement appears (Fig. 76).
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.
Since the appliance 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 30.
