5. Press START/STOP key to activate the measurement in continuous mode
6. Wait for a stable result at display and press again START/STOP key to stop the
measurement or wait for the end of the set Timer. The result of test is shown at display
(see Fig. 21 or Fig. 23) with meaning of items descript in Table 4
7. Wait for the object under test to discharge
8. For saving the result see § 7

5000V Set test voltage
U=5323V Applied test voltage
I=266nA Applied test current
19.9G  Result of insulation measurement
C=0.0nF Capacitance of measured object
Tm:01min 04s Timer information – test duration
Bargraph Analogue representation of result
Rmax=20.G  Maximum value of result (only if timer is enabled)
Rmin=19.9G  Minimum value of result (only if timer is enabled)
Table 4: Meaning of parameters of insulation measurement
CAUTION
 If the timer is disabled then OFF is displayed instead of the timer value
 During a measurement, the timer information displays the time needed to
the complete the measurement (tr) while after the completion the test
duration (tm) is displayed
 A high-voltage warning symbol appears on the display during the
measurement to warn the operator of a potentially dangerous test voltage
 Value of capacitance is measured during the final discharge of the test
