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