• Menu index “3B2” CHLORINE/BROMINE FREQU OUT
The frequency output (Open collector circuit) can be used to control and guide the dosing of a remote
system in proportion to the Chlorine measurement.
• Menu index “3B3” CHLORINE/BROMINE mA OUT
Note: The value set under the HOLD mA item is automatically generated by the instrument when a functional Hold
is present, for example due to a lack of water Flow Alarm or an enabled Voltage Input.
• Menu index “3B4” CHLORINE ALARM
Note: The Holding Range and Holding Time items must be used together.
The indicated function controls the chemical measurement at a constant value for long periods of time.
This alarm can help to prevent incorrect dosing as a result of damaged probes.
• Menu index “3B5” Reference temperature for CHLORINE/BROMINE measurement
Select 18, 20 or 25°C as the reference temperature for the chlorine measurement.
• Menu index “3B6” Compensation of chlorine/bromine based on conductivity of the water.
Select reference conductivity between Low less than 9 mS and High greater than 9 mS.
