ANALYZER PROGRAMMING
When power is first applied to the analyzer, programmable
parameters of the analyzer are set to default values estab-
lished at the factory. These values or any new values entered
by the operator are stored in nonvolatile EEPROM which
will retain the programmed values in the event of power
failure. All programmable parameters are viewed or ad-
justed via dedicated push buttons.
To check the setting of any programmable parameters, sim-
ply press the dedicated key and the setting will be shown
on the display.
To change the setting, enter the
new setting into the display using
the and keys and then quickly
press the dedicated key twice .
The display will show the entries for approximately 2 sec-
onds after the last key stroke and after altering programmable
parameters. The display will
then revert automatically to a
Chlorine concentration display.
PROPORTIONAL DOSING
Proportional dosing establishes and maintains a controlled
and consistent concentration level.
• Press SETPOINT. The display will show the current dosing
setpoint.
Note
If the analyzer has been turned on for the first time, “2.50”
will appear as default setpoint.
• Enter the desired setpoint value, e.g. 3.00, using the
and keys.
