“Measurement interval” slide controller
The interval is the time difference between two analyses.
You can enter values within the range from 10 to 60 minutes. The
factory default setting is 15 minutes.
“Measurement phase” slide controller
Analyses in the interval set shall be carried out only during this pe-
riod. Outside of the measurement phase, the device will wait for a
start signal and will output a current of 4 mA.
You can enter values within the range from 10 to 12 hours. The fac-
tory default setting is 3 hours.
Internal “Flush time”
To guarantee that the water sample being analysed is current, the
sampling pipe must be sufficiently flushed beforehand over its entire
length.
Flushing is carried out by simultaneously opening the inlet and outlet
valves of the device.
You can enter values in the range of 0 to 99 seconds. The factory
default setting is 0 seconds.
0 seconds means that no internal flushing should take place.
"Interval pause after water shortage"
If the instrument detects a lack of water during an analysis, the meas-
urement is repeated twice before an alarm is issued.
Set the time until the next repetition here.
You can enter values in the range from 0 to 180 minutes. The fac-
tory default setting is 0 minutes.
0 minutes means that there is no pause between repetitions.
