The unit has a timer switch (No. 5) which switches off automatically after 60 seconds, a selector knob
(No. 4) and a counter electrode socket (No. 7). The selector knob offers the choice of cleaning or
chloridizing functions. For oxygen or ozone sensors, the anode, cathode and guard ring electrode
cleaning positions are available. The two selector positions in the chloridizing section cover
dechloridization and rechloridization of hydrogen sensors. The counter electrode socket takes the
banana plug from the regeneration cell.
For electrical testing there are eleven sockets (No. 2) to accept banana plugs. Each of the sockets is
connected to one of the ten pins of a sensor LEMO plug (including a shield plug). By connecting an
ohmmeter across two of the sockets sensor resistances can be measured and the state of the sensor
checked.
