3.3 Measuring the voltages from the control circuit board to
the scaler electronics unit

Remove cover and casing,

see instruction section 1

Measure the output voltage from control circuit board to scaler electronics unit.
Pin 5-6 and pin 5-10 (see pictures above), reading should be 10 +/- 0,5 Vdc when running at working
mode 3 and with foot control at maximum power.

Also measure the ON-signal to the scaler, pin 5-8. When the foot control is activated the reading
should drop from approx. 15 Vdc down to zero. (Working mode 3 and with foot control at maximum
power.)
