Calibration - ECOLAB MULTRONIC Bedienungsanleitung

The limit-contact (L-) and limit-contact (L+) functions are used to specify the lower and
upper limit value for the limit value alarm.
Value range (depending on the set measuring range):
Measuring range
0..14 pH
2..12 pH
3..8 pH
The limiting value monitoring function can be turned off through selecting the off
setting.
The switching hysteresis around the limit contact can be specified in % with the limit-
contact (X2SD) function.
Value range: 0.0 % to 30.0 %
The controller of a different module can be specifically turned off with the limit controller
function as soon as the limit range has been reached.
Value range (module on plug-in connection 1): none / all / module 2 / module 3
Through selecting the module selection function one returns to the controller parameter
module selection.
The page 1 function is used to display the specific parameters of the selected
