Paramagnetic O2 Purity Analyzer

Maintenance

Teledyne Analytical Instruments

To access the Universal Power Supply and electronic PCB’s, the rear

panel must be removed. This is accomplished by removing the 10 cross-
head screws at the locations shown in Figure5 -4.

Figure 5-4: Rear-Panel Screws

5.5 Cleaning

If the instrument is unmounted at the time of cleaning, disconnect the

instrument from the power source. Close and latch the front -panel access
door. Clean outside surfaces with a soft cloth dampened slightly with plain
clean water. Do not use any harsh solvents such as paint thinner or
benzene.

For panel-mounted instruments, clean the front panel as prescribed in

the above paragraph. DO NOT wipe the front panel while the instrument
is controlling your process.
