pH sensor - parameter

10.2

Damp or not the variations of the measured

pH-values

The parameter

Filter response time

makes it possible to damp or not the variations of the measured pH-

values. If the variations of the measured values are not damped, then the raw measured values are sent on

the fieldbus.

By default, the parameter

Filter response time

is set to 3 s.

To change the value of the parameter

Filter response time

, do the following procedure:

→

Make sure that the login user level is

Installer

. If necessary, change the user level. Refer to chpt.

9.4.

tab

Parameter

→

Select

Filter response time

→

Enter a value between 0 s and 10000 s, depending on your installation. To not damp the variations of the

measured values, set the parameter to 0 s. The higher the time value is, the more the variations of the

measured values are damped.

→

Validate with

If the parameter is set to 0 s, then the variations of the measured values are not damped.

If the parameter is set to a value other than 0 s, then the variations of the measured values are damped.

10.3

Monitor the impedance value of the reference

electrode

The water pH is correctly measured if the reference electrode is in contact with the water sample. The

impedance value of the reference electrode shows whether the electrode is in contact or not with the water

sample:

•

If the impedance value is less than 160 k

, then the reference electrode is in contact with the water

sample;

•

If the impedance value is between 160 k

and 1 M

, then the reference electrode is not in contact with

the water sample.

You can be warned automatically when the impedance value of the reference electrode is not in contact

with the water sample. Do the following procedure:
1. Make sure that the login user level is

Installer

. Refer to chpt.

9.4.

Activate the measurement of the impedance value of the reference electrode. Refer to chpt.

10.1.

Do not configure and activate the low warning limit.

Configure and activate the high warning limit of the impedance value.
