Activating/deactivating tare clears the max- & min-memories.
Zero-Point Adjust: (for gauge pressure sensors only) If there is no pres-
sure applied to the pressure ports the device will display 0.
If there is a permanent offset (and the device is being used
under steady conditions), a permanent zero point adjust-
ment can be carried out. To carry out the adjustment,
press ´Tare´ for approx. 5 seconds. (Please note: A zero-
point adjustment can only be made if the difference bet-
ween the display value and the factory calibration value is
less than 2 %! E.g. for a measuring range of 0 ... 25 bar,
=> zeropoint adjustment up to 0.5 bar possible). To revert
to the factory calibration, press ´Tare´ for approx. 7 sec-
onds.
If a zero-point adjustment has been made, this will be signalled by the
message "nuLL-Corr" being displayed briefly as the device is turned on.
