where the minimum deviation (D1 or D2) is 0.5% of the maxi-
mum range value.
Note When a wrong setup value is confirmed,
the controller does not skip to the next setup
item but remains in the current item dis-
playing a flashing “ERROR” indicator un-
til the parameter value is changed by the
user (the same is also true for the setup code selection).
Note In some circumstances, the user cannot succeed in setting a
parameter to a desired value if the related parameters are not
changed beforehand; e.g. to set a EC high setpoint to 10.0
mS the high alarm must be set to a value greater than 10.0
mS first.

Note The process controller automatically checks to ensure that
the entered data matches other related variables. If a wrong
configuration is entered, “ERROR” blinks on the LCD to prompt
the user. The correct configurations are the following:
If M1= / 0 then S1 HA, S1 LA;
If M2= / 0 then S2 HA, S2 LA;
If M1= 1 then S1-H1 LA;
If M1= 2 then S1+H1 HA;
