Test mode Switch between basic modes.
The various surgical effects of this unit call for a high dynamic perfor-
mance in terms of output voltage, current and power. For this reason
the high-voltage power supply unit and the high-frequency generator
offer many switching options which are broken down into 4 basic
modes to simplify handling in the test program:
• SOFT (SOFT COAG)
• AUTO (AUTO CUT)
• FORC. (FORCED COAG)
• SPRAY (SPRAY COAG)
Power supply voltage Set power supply unit voltage.
ATTENTION! Never switch high voltages (FORC. / SPRAY) to a bipolar or multi-
functional receptacle.
ATTENTION! When there is no load the generator may produce high voltages,
possibly resulting in irreparable damage to components or assem
-
blies. The power supply unit voltage should therefore not be set
too high.
Maximum HF voltages: SOFT 1000 V
AUTO 1000 V
FORC. 2500 V
SPRAY 4000 V
ATTENTION! Unlike in the regular operating modes FORCED COAG and
SPRAY COAG no leakage current suppression is provided for the
generator control. For this reason it should only be activated briefly
when there is no load as otherwise this may subject the transistor
in the generator discharge circuit to thermal overload.
