Alarm Low: If the measured value falls below the alarm low value, the
alarm relay is activated and E002 is displayed in the message list.
pH sensor
Range: -3 pH to +15 pH
Hysteresis: Within the hyst. range, the relay does not switch. This
prevents damage of relays contacts when the measured value fluc-
tuates around the alarm value.
pH sensor
Range: 0.00 pH to 2.00 pH 0 mV to +200 mV
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 al-
ways be indicated in the display, pending error list, saved in the
message list and the logger.
Available values: Yes or no
NOTICE: 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
value 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 val-
ue, 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
