Measured value checkout time
IMPORTANT
This function may not be activated for applications in which it can be assumed that the
measured value will not change.
This function tests whether the measured value varies from that of the sensor (at the measured value input)
within the “Measured value checkout time”. It is assumed that it will do so for an intact sensor.
If the measuring value does not change during this checkout time, the DULCOMETER
®
D1C sets the
control variable to “0” and the alarm relay drops out. The LCD display shows e.g. the message “Check Cl
probe”.
