Setting the sample gas purging time

Requirement

The sample gas purging time is the time that elapses from switching of the solenoid valve

until measurement of the sample gas. Because of the different use environments, it is

possible to assign the sample gas purging time.

Depending on the hardware of the device, the sample gas purging time can be set device-

specific or module-specific:

Table 7- 23

Device-specific

If only one analyzer module is installed or if a

common gas path exists for two analyzer

modules (series connection).

Check the setup of the gas path as well as the parameter assignment of the process tags

before you set the sample gas purging time: [2.12] Settings > Gas path/process tag label

(Page 69).

Procedure

1. Main menu > "2. Settings" > "08. Calibrations" > "1. Setpoints, tolerances, purge

2. Specify duration: "Sample gas purging time" parameter field.

Effect of the sample gas purging time

time" > "4. Sample gas purging time"

– Authorize access with Expert PIN, if necessary.

– Increase/reduce preset value.

– The device stays in "Function check" operating state for the assigned duration.

Module-specific

If two analyzer modules with separate gas paths

are installed, you must set the parameters

separately for each analyzer module.
