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 is 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:
1.
Key in password “022” as per procedure in Section 5.
2.
The screen will scroll P2.0 and SP2. Press ENTER three times.
3.
The screen will scroll P2.3, HYS2, and current hysteresis value.
4.
Press ▲or ▼keys to adjust hysteresis value.
5.
Press ENTER to confirm. Press ▲and ▼keys together to return to P2.0.
Press ▲and ▼keys together to return to Conductivity measurement mode.
