4.1.6 Routine Operational Calibration

Span calibration should be checked every two to four weeks on a
routine basis. Whenever there is the slightest suspicion of abnormal perfor-
mance, an inspection of the possible trouble should be made, followed by
span calibration. Use trouble shooting procedures as required.

The combustibles monitor comes ready to operate. Power is con-
nected to it through a terminal strip in the oxygen analyzer (see Figure 6).
The combustibles monitor has Its own POWER switch located on the front
panel of the control unit. Alarm relay and analog output terminals are
located in the oxygen analyzer.
When ready to operate, follow the startup procedure in Section 4.3
Startup Procedures, except as follows:
(1) Turn on the air supply and adjust the AIR regulating valve on
(2) Open the SAMPLE toggle valve and open the sample/bypass
(3) Start up the svstem pump and with either calibration air or
Note: Do not attempt to run a higher flow rate than 3 SCFH. Higher flow
rates will cause the water trap to break and all flow will be lost
through the drain.
(4) Turn ON the POWER switch of the combustible monitor
(5) Shut off the SAMPLE toggle valve and let only air flow
