measures no throughput for about one hour, it automatically switches off.
During operation with the optional power supply unit, the combined meter
does not automatically switch off and cannot be switched off manually. If the
combined meter has switched off automatically, it will automatically restart
once the throughput (> 2 l / min) resumes. If the combined meter is switched
off using the ON/OFF key, it will not restart automatically.
Auto mode
Press the key twice in quick succession to start automatic monitoring by
the combined meter. The symbol is shown to indicate that monitoring
has been enabled. In auto mode, the meter only takes measurements when
water is actually passing over it. If the throughput is interrupted, the meter
continues to show the last captured value. When a throughput is present, the
meter takes a new reading of the conductivity value after every 10 litres and
displays it. If the limit is exceeded in two successive measurements, the
display continuously flashes red and an acoustic alarm sounds. In addition,
the floating contact is switched over. If the key is pressed for a third time,
the meter exits auto mode.
Litre-gallon key
Briefly press this key once to select the throughput indication in litres per
minute (l / min) or gallons per minute (GPM).
Press the key for approx. 3 seconds to reset the total throughput volume
("JOB") to 0. We recommend resetting the "JOB" to 0 after every resin change
so that the residual capacity of the ion exchange resin can be estimated and
compared. The TOTAL litres cannot be reset to 0!
5.5. Fill water quality indicator (11)
The fill water quality is indicated using the traffic light principle.
Green = Resin is ready for operation
Amber = Resin will soon be spent
