- For continuous adjustment of the pulsing / main current
- For continuous adjustment of the pulse frequency, depen-ding on which
frequency range has been preselected by switch (27).
- The setting for the background current is made as a percentage of the value
set for the pulsing current I
- Setting dial for pulse / interval relationship = this dial is for setting the relati-
onship, in percentage terms, between the pulsing current phase and the
background current phase.
Duty cycle dial (26) is in scale position 10,
- Short pulsing current phase of 10 %
- Long background current phase of 90 %
- Low degree of heat impact.
- Pulsing current phase and background current phase are equally long (each 50
%)
l Means medium degree of heat impact.
Duty cycle dial (26) is in scale position 90,
- Long pulsing current phase of 90 %
- Short background current phase of 10 %
- High degree of heat impact.
