8.5.5.2 Adjustment by DPD
If you don’t have the buffer solutions available, or if you sense these are not in good
condition, you can proceed the calibration with the DPD photometer. Nevertheless, be
aware that this process can increase the degree of error so you should always give
preference to the calibration with the standard solutions.
Necessary material:
•
DPD photometer
•
Phenol Red Tablets
1. Remove a sample of the pool water as close as possible to the sensor
2. Make a blank reading with the sample without tablet
3. Insert the phenol red tablet and do the reading
4. Press the knob and wait as instructed on the screen
5. Insert the value given by the photometer by rotating and pressing the knob
6. Press the knob again to finish the process
To cancel the calibration procedure, just switch the equipment off and on before
finishing; the calibration will not be changed.
8.6 Alarms Menu
If there is an active alarm, the equipment will indicate it in the bottom right of the
front panel. This information will disappear when the problem is solved.
The system can indicate 3 types of alarm:
- “pH Fault” indicates that the pH reading is outsider the limits defined in the setup
menu;
- “Empty Tank” indicates that the pH solution tank is empty;
- “pH Timeout” indicates that the time of the equipment reaction to an unchanged
reading was exceeded;
8.6.1 pH Fault Alarm
This alarm will occur when the pH value is outside the predefined limits. This alarm
may be triggered when the compensation solution does not correspond to the
indication, or that the pump is not well regulated, or that it is not primed, or it doesn’t
have the proper capacity for the pool volume.

•
the dosing pump is properly connected to the SANUS equipment
