Hysteresis: Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value fluctu-
ates around the alarm value.
pH sensor
0.00 pH to 2.00 pH 0 mV to +200 mV
Range:
Delay: Duration, the activation of the alarm relay is retarded after the
measuring value has risen above/fallen below the programmed
alarm. Range: 0–28'800 Sec
Sample Flow: Define at which sample flow a flow alarm should be
issued.
Flow Alarm: Program if the alarm relay should be activated if there is
a flow alarm. Choose between yes or no. The flow alarm will always
be indicated in the display, pending error list, saved in the message
list and the logger.
Available values: Yes or no
Note: Sufficient flow is essential for a correct measurement.
We recommend to program yes.
Alarm High: If the measuring values rises above the programmed
value E009 will be issued.
Range: 0–200 l/h
Alarm Low: If the measuring values falls below the programmed val-
ue E010 will be issued.
Range: 0–200 l/h
Sample Temp.: Define at which sample temperature an alarm
should be issued.
Alarm High: If the measured value rises above the alarm high value,
the alarm relay is activated.
Range: -25–270 °C
Alarm Low: If the measured value rises above the alarm high value,
the alarm relay is activated.
Range: -25–270 °C
Case Temp. high: Set the alarm high value for temperature of elec-
tronics housing. If the value rises above the programmed value E013
is issued.
Range: 30–75 °C
Case Temp. low: Set the alarm low value for temperature of electron-
ics housing. If the value falls below the programmed value E014 is
issued.
Range: -10–20 °C
