Cleaning the Penning Gauge
Replacing the body tube is recommended in the maintenance of the Penning
gauge. However, to clean the anode assembly, cathode tube, cathode plate, and
body tube, complete the following steps:
1 Remove the electrode from the body tube
Using a flat spanner unscrew and remove the collar. Then, using the circlip
pliers, remove the anode assembly, cathode plate, and cathode tube from
the body tube (Figure 123 on page 4- 146).
