This may be necessary to match a process beyond the normal operating range.

WARNING

HAZARDOUS RF VOLTAGE - CONTACT CAN CAUSE DEATH, SEVERE INJURY
OR BURNS

Any work requiring the removal of covers or panels must only be

performed by authorised personnel who are aware of the hazards
involved.

Turn off the RF generator completely before removing the smaller L-section cover. This
reveals the ends of the two variable capacitors and mounting positions for extra fixed
capacitors.

CAUTION

Components fitted must be suitable for RF power service. Low power circuit

devices will overheat quickly.

Suitable components are given in the following table:

OIPT Part Number

Capacitance

Rating

94-ECC1209 90pf

1kV

94-ECC1218 180pF

2kV

Change components according to the following table:

C1 going maximum

Add fixed capacitance in parallel with C1

See following

NOTE.

C1 going minimum

Remove fixed capacitance in parallel with C1 Minimum is zero

C2 going maximum

1. Add fixed capacitance in parallel with C2
2. Increase coil inductance

See following

NOTE.

C2 going minimum 1. Remove fixed capacitance in parallel

with C2

2. Decrease coil inductance

Minimum is zero fixed capacitance

NOTE:

Variable capacitors C1 and C2 have a maximum capacitance of 1000pF and 500pF respectively.

For each of these variable capacitors there are three positions for fitting parallel ‘padding’

capacitors. Therefore, a maximum of 3 x 180pF padding capacitors could be fitted but usually
there is no need to fit more than one padding capacitor (i.e. 180pF).
