7.5 CONFIGURING THE MEASUREMENT.

7.5.1 Purpose

This section describes how to do the following:

1.Program the analyzer to measure total chlorine. This step is necessary because the analyzer can be used with other sensors to measure other chlorine oxidants.

2.Set the level of electronic filtering of the sensor current.

3.Set the display resolution.

7.5.2 Definitions

1.CHLORINE OXIDANTS. Although the TCL is used to measure total chlorine only, the 1056 analyzer used with the TCL can be used to measure other chlorine oxidants, for example monochloramine and free chlorine.

2.FILTER. The analyzer applies a filter to the raw sensor current. The filter reduces noise but increases the response time. The available filter(s) depend on the time setting. If the filter is between 0 and 10 seconds, the analyzer applies a window filter. A window filter averages the measured value within the filter time. For exam- ple, if the filter is 5 seconds and a step increase is applied to the input, the displayed value increases linearly, reaching the final value after 5 seconds. If the filter is set to greater than 10 seconds, the analyzer applies either an adaptive filter or a continuous filter. An adaptive filter discriminates between noise and real process change. It filters changes below a fixed threshold value but does not filter changes that exceed the threshold. It is best used in situations where the noise is relatively low. A continuous filter dampens all changes. The fil- ter time setting is approximately equal to the time constant, the amount of time required for the reading to reach 63% of the final value following a step change.

3.RESOLUTION. If the chlorine concentration is less than 1.00 ppm (mg/L), the display resolution can be set to 0.XX or 0.XXX.
