STARTUP, FUNCTIONAL CHECKS, AND INITIAL CALIBRATION

3.4.1 Startup

1.Turn on the instrument by pressing the on/off rocker switch on the front panel. The display should immediately light, showing the computer’s memory configuration, then the instrument type - Model T265. A diagram of the software menu trees can be found in Appendix A of this addendum.

2.Thirty minutes after power-up an internal solenoid valve will open allowing Nitric Oxide gas to flow. Check the Nitric Oxide flow “NO FLOW” test function (TEST button, <TST TST> buttons) on the front panel to verify that the flow is 5 cm³/min ± 2. cm³/min.

If the flow is out of this range, check the Nitric Oxide pressure “NO PRESS” test function on the front panel display, to verify that the pressure is set to 5 PSIG +/- 1 PSIG.

If the pressure is out of this range, check that the cylinder regulator is set to 20 PSIG, then drop the front panel and use a flat head screw driver to turn the NO Pressure Adjustment Stem (Figure 3-3)to adjust the NO pressure regulator: clockwise to increase; counter-clockwise to decrease.

Note

The NO pressure sets the flow; therefore, the ‘NO PRESS” test function

 

is of greater importance when setting up the analyzer. The “NO FLOW”

 

test function is only provided to indicate the presence of gas flow.

 

The Model T265 analyzer requires about one hour for all internal

 

components to heat to operating temperature.

IMPORTANT

IMPACT ON READINGS OR DATA

 

It is recommended that the analyzer operate for about four (4) hours before

 

calibration and the collection of reliable readings.

3.When the instrument is warmed up, check the TEST functions. All of the readings should compare closely with those in Appendix C of this addendum.

4.After checking the TEST functions, calibrate the instrument as presented sequentially in Parts 1 through 3 in Section 3.4.2, which follows.

3.4.2Initial Calibration

The initial calibration is accomplished in three parts:
