1.7 Operation verification

The Model 450H Monitor is now ready for operation.

1.Read Sections 1.3 and all of Section 2 of the manual to understand the Monitor's operation.

2.Turn on the power by pressing the on/off switch (see Figure 2.1). The display should turn on and green (sample) status LED should be energized. The yellow "fault" light may also be on until the temperatures and voltages are within operating limits. Clear the fault messages.

3.Sample Flow - Adjust to 0.5-2.0 L/min using needle valve (See Figure 1.6)

4.After a 20 minute warm-up, review the TEST function values in the front panel display by pushing the keyboard button labeled TST>. Not every TEST function is a diagnostic of correct monitor operation, therefore TEST functions not covered below can be ignored for now.

5.O3 REF, O3 MEAS - TEST function values should be between 4200 mV and 4700 mV.

6.Pressure – 14.5-15.2 psia at sea level. Other values will be displayed depending on altitude of monitor.

7.Sample Temp - 20 -50oC

8.Box Temp - Ambient +10 oC

9.If the TEST functions are within the limits given above the instrument should function correctly. If there is a problem please read the manual and check your set-up.
