P1.3: 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: Low set point is 200.0 µS/cm and hysteresis 100.0 µS/cm, relay will

activate when value drops below 200.0 µS/cm, but will not de-activate till

measured Conductivity value rises above 300.0 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

1. Key in password “022” as per procedure in Section 5.

2. The screen will scroll P1.0 and SP1. Press ENTER three times.

3. The screen will scroll P1.3, HYS1, and current hysteresis value.

4. Press ▲or ▼keys to adjust hysteresis value.

5. Press ENTER to confirm. Press ▲and ▼keys together to return to P1.0.

Press ▲and ▼keys together again, to return to Conductivity measurement

mode.
