7. Power up the analyzer:
It is necessary to work with the Electronics Enclosure door open after
replacing source lamps so that adjustments can be made to the lamps.
When the analyzer’s covers and doors are open, take appropriate precau-
tions to avoid electrical shock. Hazardous voltages are present inside.
GP Analyzers:
Close the ASR Probe and Oven Heater fuses and replace the Sample
and Vent Line fuses.
Close the Analyzer fuse to apply AC power to the analyzer.
Purged Analyzers:
Insert the key into the Purge Bypass Switch and switch it to the
“BYPASS” position (follow company policy).
[Special Conditions for Safe Use]
The analyzer may only be energized by using the Purge Bypass
Switch with permission of the works manager or his proxy. The per-
mission may only be given when it is made sure that during the time
the system is energized by using this switch an explosive atmosphere
is not present or when the necessary protective measures against
explosion hazard have been taken (“hot permit”).
The analyzer enclosure may not be opened when an explosive atmo-
sphere is present.
Close the power-disconnect switch to apply main AC power to the
analyzer.
8. Manually Zero the analyzer.
After the Zero is complete, allow the analyzer to stabilize for 5 minutes
before continuing.
9. Initiate an Auto-Setup and continue with this procedure only after the
completion number is between 0.75–1.25.
