Resistivity (Mohm)
Real time displays station resistivity reading (Mohm).
Low Resistivity Alarm Set Point
– Set station low resistivity alarm
set point. Alarm message “LOW RESISTIVITY ALARM “will
prompt when resistivity rate is lower than this set point
Low Resistivity Refill Set Point
- Set resistivity set point to trigger
fresh DI Water to refill into the tank.
Refill Cutoff Hysteresis Value
– Set resistivity hysteresis value
above Low Resistivity Refill Set Point to stop fresh DI water refill.
Refill will stop when resistivity has risen to a value = Low
Resistivity Refill Set Point + Refill Cutoff Hysteresis Value.
Hysteresis value is the value added to low resistivity refill set point
to trigger refill to turn off.

Weir Pump Delay Off Time Setting
– – Set the timer to turn OFF weir
pump after a delay time. When weir liquid sensor detects presence of
fluid, this timer will start to count down and weir pump will turn OFF
after the delay time is finished.
Example: Set 30 seconds, if the weir liquid level has reached high
liquid level, timer will start to count down for 30 seconds and will turn
off pump.
Note
: Maximum setting range of Weir Pump Delay Off Time Setting is
120 secs.
