5.3 Alarms
The Alarms menu displays all alarm messages. Use the Next key to scroll down the list, or the
Prev key to scroll up the list. There are no programmable parameters in this menu. No access code
is required to enter this menu.
Press the Exit key to return to the Main Menu.
5.4 Calibration
The Calibration menu is used to calibrate the sensor inputs, as well as any optional 4-20 mA
inputs. The list of options displayed will depend upon what options are installed in your
WebMaster. Not all of the menus described below will necessarily appear on your display. An
access code will be required to enter this menu. Use the Arrow keys to enter the access code, then
press the Enter key to continue.
The possible inputs to calibrate include:
System Conductivity
System Temperature
Makeup Conductivity (only if the makeup conductivity option board is installed)
Makeup Temperature (only if the makeup conductivity option board is installed)
pH (only if the pH option board is installed)
ORP (only if the ORP option board is installed)
4-20 mA Input #1 through #8 (only if the optional 4-20 mA input card is installed)
The possible calibration choices will be displayed. Use the Next key to move the cursor down the
list, or the Prev key to move the cursor up the list. Once the cursor is on the desired menu, press
the Enter key to start the calibration procedure.
System/Makeup Conductivity Calibration – Standard Contacting Electrode
“1 pt Process Cal – Calibrate” will be displayed. Press the Enter key to start the calibration.
The reading from the system conductivity sensor will be displayed. Measure the conductivity of
the system water using a hand held conductivity meter, and use the Arrow keys to enter the actual
value. Press the Enter key to highlight ‘CONTINUE’, then press Enter again to put the new value
into memory.
If the calibration correction factor is within +/- 50% of the uncalibrated conductivity, the display
will say “Cal Successful”. Press the Enter key to resume control of the conductivity.
If the calibration factor is outside of +/- 50% of the uncalibrated conductivity, the display will say
“New value out of limits, Cal Fail”. The most likely cause of this is a dirty sensor. Refer to Section
6 for cleaning instructions. If cleaning fails to cure the problem, refer to Section 7 for
troubleshooting help.
