energized when the measured value is greater than the alarm set point value. The
ALARM SET POINT LED will be OFF and the ALARM output relay will be
de-energized when the measured value is less than the alarm set point value.
2.2 Set the ALARM SET POINT HIGH/LOW SELECT switch to the LOW position.
The ALARM SET POINT LED will be ON and the ALARM output relay will be
energized when the measured value is less than the alarm set point value. The
ALARM SET POINT LED will be OFF and the ALARM output relay will be
de-energized when the measured value is greater than the alarm set point value.

Set point hysteresis
The hysteresis of the model 3672 is factory set to ±0.1 pH (±10 mV). For HIGH
ALARM settings, the trigger ON point is 0.1 pH (10 mV) above the set point values
and the trigger OFF point is 0.1 pH (10 mV) below the set point values. For LOW
ALARM settings, the trigger ON point is 0.1 pH (10 mV) below the set point values
and the trigger OFF point is 0.1 pH (10 mV) above the set point values.
