Operation Manual

GMC-I Messtechnik GmbH 39
4.2.4 Pulse Control Mode
We recommend selecting the pulse control mode for
troubleshooting purposes (arc-over pinpointing).
Interrupting current I
MAX
is fixed to a value of approximately
125 mA with feature B1, and to approximately 5 mA with feature
B2 in the pulse control mode. If this value is exceeded, test
voltage is switched off within 0.5 ms. After approximately 0.6 s,
test voltage is increased from 0 to its final value within a period of
0.2 s, or is switched back off if interrupting current is exceeded.
Ð Set I
MAX
to >>>>>>> in order to activate the pulse control
mode (see chapter 4.2.2 on page 36).
Ð If continuous operation is required, set test duration to >>>>>>>
as well (see chapter 4.2.2 on page 36).
