Operation
WARNING: NEVER connect or disconnect the electrode
with the generator connected to the mains supply.
WARNING: This equipment must not be used in any
combustible atmosphere; the high voltage discharge will
cause a spark from which an explosion could result.
WARNING: This equipment must not be exposed to damp or
wet conditions, or where the amount of conductive dust is
greater than would occur in a normal situation.
Screw the flexible probe electrode into the red end of the PST-100. Set the
output control knob on the rear fully anti-clockwise. Connect the plug to
the mains supply socket.
Setting the Output Voltage
Hold the end of the flexible probe at the determined distance for a spark
to jump to an earthed metal test piece, squeeze the trigger and turn
the output control knob slowly clockwise until the output voltage is high
enough to cause a spark to jump the gap. Alternatively — for increased
accuracy in setting the output voltage — a Buckleys Spark Gap Setter
(part number A2) may be used.
The probe should always be kept moving when testing as the high voltage
and ring frequency
combination
may cause heating in the article under test
which may result in burning. The output control should be adjusted for the
lowest output at which an effective test can be carried out.
When testing is complete, release the trigger to switch off the PST-100’s
output.
Disconnect the PST-100 from the mains supply before attempting to
remove the flexible probe.
