P2.3: Set Hysteresis value

Hysteresis prevents rapid contact switching if measured value is fluctuating near

the set point. Once activated, relay will not de-activate until measured value

reaches set point plus hysteresis value.

Example: High set point is 1800.0 µS/cm and hysteresis 100.0 µS/cm, relay will

activate when value rises above 1800.0 µS/cm, but will not de-activate till

measured Conductivity value drops below 1700.0 µS/cm.

Default hysteresis value is 5% of full scale. The hysteresis window can be set to

any value within the range shown below:

Conductivity Range Range No., R Hysteresis Window

0.00 – 20.00 µS/cm 1 0.00 – 2.00 µS/cm

0.0 – 200.0 µS/cm 2 0.0 – 20.0 µS/cm

0.0 – 200.0 µS/cm 3 0.0 – 20.0 µS/cm

0 – 2000 µS/cm 4 0 – 200 µS/cm

0.00 – 10.00 mS/cm 5 0.00 – 1.00 mS/cm

0.00 – 20.00 mS/cm 6 0.00 – 2.00 mS/cm

0.0 – 200.0 mS/cm 7 0.0 – 20.0 mS/cm

0.0 – 200.0 mS/cm 8 0.0 – 20.0 mS/cm
