Changing the Fixed Capacitor Setting (Model 041 5 2 MHz
Units Only)
The V arioMatch match network Model 0415 2 MHz unit is equipped with a circuit
board containing additional fixed capacitors You can switch these capacitors in
parallel to the load capacitor to increase the capacitance.
To Change the Capacitor Settings:
1. Tum off RF from the generator.
2. Disconnect AC MAINS.
3. Disconnect RF in (from the RF-GENERATOR).
