Control Time Measuring Value
IMPORTANT
This function may not be activated for applications where it can be assumed that the
measuring value does not change.
This function checks whether the measuring value from the sensor (measuring value input) changes within
the “control time measuring value”. It is assumed that the value does not change for an intact sensor.
If the measuring value does not change during this control time, the DULCOMETER
®
D1C sets the control
output to “0” and the alarm relay drops out. The LCD display shows e.g. the message “check mV-probe”.
IMPORTANT
When changing the range adjustment, the adjustments in all menus have to be checked!
