Appendix 1: Simple Explanation on the Function of Hysteresis

The controller relay activates when the set-

point is reached. In the reverse direction, it

does not de-activate when the value

reaches the set-point. Instead, it continues

to be active till the value reaches the

amount set by the Hysteresis band.

Appendix 2: Factory Defaults

Resetting the controller to factory default settings (See program P7.0) clears

all calibration data and most other setup functions.

The following settings will remain unchanged:

1. Measurement range

2. Temperature compensation mode (ATC or MTC)

3. Temperature offset calibration value, if in ATC mode.

Conductivity Defaults

Conductivity range Remains unchanged at last selected range

Set point 1 10% full scale / Hyst. 5% full scale / Low

Set point 2 90% full scale / Hyst. 5% full scale / High

Temperature Defaults

Temp. Compensation mode remains unchanged

MTC mode reset to 25

C if in MTC mode

ATC mode remains at last calibration if in ATC mode

Temperature Coefficient 2.1 %

Normalization Temperature 25.0
