OPERATION NOTES

AVTM21-415Ja Rev. A June 2005
In any case, when used for this purpose the test set can
continue, for long periods, to generate arc-overs at a rate not
exceeding one discharge every three seconds. Attempts to
shorten this time interval may result in trip-out. Trip-out warns
that the thermal limit of the components will shortly be
reached unless the discharge rate is reduced by lowering the
voltage or adding series resistance. When series resistance is
added, care must be taken to avoid hazards from the new
connection. When using the stabilizer in the "IN" position the
voltage control should be set to comply with the discharge rate.
EXTERNAL CURRENT METER
To read or record the test current, connect a suitable
instrument to a two-wire phone plug that mates with EXT.
INST jack J1. The tip of the plug will be positive, the ring
negative. The external meter impedance must not exceed
10,000 ohms. The meter should be protected against
overcurrent transients.
