Maintenance
7.1 Automatic maintenance and
calibration check intervals
The electronics module offers the option of
using automatic maintenance and calibration
check intervals for disinfection, and pH, ORP
(Redox) and fluoride measurement. In as-deli-
vered status, the maintenance and calibration
intervals are disabled. To enable the mainte-
nance intervals for disinfection, pH and fluo-
ride measurement:
1 Call up the Home menu.
2 Select the desired measurement (e.g.
Chlorine free). The “Measurement“ menu
opens.
3 Tap the
Settings menu. The settings
menu for the selected measurement
opens.
4 “Maintenance interval” menu opens.
5 To enable the maintenance interval, set
the parameter “Message” to “On” under
the heading Cells and, under the parame-
ter “Interval,” enter the number of days
after which you wish to receive a remin-
der to carry out sensor calibration.
When the set interval expires, an orange
message appears on the electronics
module reminding you to carry out sensor
calibration. The message can be acknow-
ledged via the message system.
To reset the maintenance interval, tap the
“Execute” button under the heading
“Cell.” The date on which the next mainte-
nance is due is recalculated and displayed
under “next maintenance on.”
