Operation
Changes to the device settings take effect immediately at the outputs.
Ready-state delay
Note the ready-state delay. After this time, the electrical outputs take a defined, stable condition.
The flow rate displayed refers to the standard condition that was set in the Spec menu under ‘REF’ /
‘Cond’.
When comparing volumetric flow rates, note the following:
–
Make sure that the volumetric flow rates to be compared refer to the same standard conditions, e.g.
operating volumetric flow rate, amount supplied by a compressor, measured values of a sensor from
another manufacturer.
–
After the supply voltage is switched on, note the warm-up time before it reaches the specified
accuracy

Reset sensor to factory setting
By resetting to the factory settings, the current settings are lost. Note down current settings before
resetting.
1. Switch off the operating voltage.
2. Press and hold the [A] button, the [B] button, and the [Edit] button.
3. Switch on the operating voltage.
