Operating Instructions
  1. Adjust voltage on back side as required (normally 220 V).
  2. Make sure the voltage control knob is fully counter-clockwise.
  3. Switch on the power supply.
  4. Connect Gunn-oscillator and/or PM 7026X (diode modulator). For use without modulation, set modulation switch off.
  5. Voltage and current reading-mode is toggled by switching the V/I switch (V for voltage).
