∆
Differential
The “DIFFERENTIAL” or dead band setting allows for a hysteresis to be
programmed in to the conductivity trip point. A programmed hysteresis value
prevents the bleed relay and solenoid from cycling on and off repeatedly
when the conductivity reading hovers around the trip set point. The value
entered in the “DIFFERENTIAL” is the amount of conductivity, away from
the trip “SET POINT”, that the bleed relay will shut off.
Press “ENTER” from this screen to change the value. The value will
have a flashing cursor indicating that it can be changed. Press the “UP” or
“DOWN” key to increase or decrease the value. Press “ENTER” to save
the “DIFFERENTIAL” value.
