Note:
Check results – tick symbols do not guarantee good installation and proper value of voltage (high
potential) on PE!
b) Testing devices of protection class 1
This function is used to test devices with protective conductor and
accessible conductive parts that are connected to PE.
• Plug the DUT (Device Under Test) into the test socket (1) of the
GT-6000 v2.
• Use the test lead with alligator clip to connect between the 4 mm
test socket (9) and a touchable metal part of the DUT.
• In mains mode (differential current measurement method is
executed and tests the device under test during operation),
connect the mains cable with the built-in connector (11) on the
GT-6000 v2 and the safety plug to an earthed socket (230 V,
50 Hz, 16 A).
• Switch on the DUT (Device Under Test).
• Start the automatic test by (short) pressing pushbutton (2).
• First test is the measurement of
the protective conductor
resistance R
PE
– Earth continuity
.
Note:
Extended version of this test is started by (long) press
to the pushbutton (2).
The preset value of the test voltage for the R
ISO
measurement is 500V. This voltage can be reduced to
250 V DC with the button (5), if needed. The selected test voltage appears briefly on the display then. By
pressing the button (5) again, test voltage will be set back to 500 V DC.
