REPEAT (F3) Repeats the insuation resistance measurement.
SKIP (F4) Skips the insulation resistance measurement.
HELP
Displays the insulation resistance test help screens.
ESC
Ends the autotest sequence.
6.6.7 Welding circuit leakage current
Measurement is described in chapter 5.3.6 Welding circuit leakage current. If this
leakage test fails or was skipped other tests will not be carried out because of safety.
Welding circuit leakage current autotest menu
Keys:
START
Starts the leakage current measurement.
Proceeds with the next leakage current measurement
(in continuous mode).
Proceeds to the next autotest sequence measurement (in single
measurement mode only).
ENTER
Proceeds to the next autotest sequence measurement (in continuous
measurement mode only).
CHG ON (F2) The instrument automatically changes L and N polarity of connected
welding equipment during the test (suitable for 1-phase equipment
with schuko plug). Higher measured current will be considered.
CHG OFF (F2) Disables the automatic change of polarity function.
REPEAT (F3) Repeats the leakage current measurement.
SKIP (F4) Skips the leakage current measurement.
HELP
Displays the leakage current test help screen.
ESC
Ends the autotest sequence.
6.6.8 Primary leakage current
Measurement is described in chapter 5.3.7 Primary leakage current. If this leakage test
fails or was skipped other tests will not be carried out because of safety.
