3-3 PREPARATIONS

After performing start-up and initialization that is described in Section 3-2,operating variables must be adjusted, i.e. the Analyzer Module is to be calibrated.

In the following, analyzer function control and calibration procedure is described step-by-step.

Figure 3-1: Measure Mode Display

After starting up the Analyzer Module, the Measure Mode Display is displayed as shown in figure 3-1.

To now check back physical parameters of the CLD Analyzer Module with the values defined in your Test Data Sheet, that you received with the analyzer, you have to select the "Physical Measurements"-Menu.

Enter the diagnostics menu "Physical Measurements" as follows, using the softkeys F1 through F5:

HISTORY

 

INFO

The menu "Physical Measurements" lets you monitor physical measurement parameters of the CLD analyzer.

During warm-up time of the analyzer, you can observe temperature values (sensor temperature, block temperature ...) of internal components.

After warm up, check

•Block Temperature

•Detector Temperature

•Converter Temperature

with the operating values given by yout Test Data Sheet. You will find an excerpt of a Test Data Sheet as an example on the next page in figure 3-3.

NOTE:

As long as operating temperatures are not yet reached by the internal components of the ana- lyzer, it is not ready for operation. Warm-up can last up to one hour.

After warm-up or during warm-up procedure of the analyzer you can connect all gas supply lines to the back of the analyzer.

Supply gases at the pressures given in the Test Data Sheet and restrict flow by an external flow limiter to 1.3 through 1.5 l/min.

Internal sample gas and ozonator pressures:

You will find internal physical paramters in the Test Data Sheet that you have received with the ana- lyzer. Externally supply gases at the given pressures with an external adjustment.

Option Bypass Flow:

Depending on measuring capillary, bypass flow should by 900 - 2,000 cc/min. If no bypass is in- stalled, restrict flow externally to 1.3 - 1.5 l/min.
