5. Min/Max: Display the respective min-/max-memory value in lower

display

Max-Function: Pressing ´Max´ shows the maximum measured value record-

ed. Pressing it again hides it. To clear the max-memory press
the

´Max´ key for > 2 seconds.

Min-Function: Pressing ´Min´ shows the minimum measured value record-

ed. Pressing it again hides it. To clear the min-memory press
the

´Min´ key for > 2 seconds.

Hold-Function: By pressing ´Store/Quit´ the instantaneous measured value

will be shown in the lower display. Pressing it again hides it.
(Only when the main menu item logger = ‘off‘ is selected).

Logger-Functions: Activated by the ´Store/Quit´ key, only if the logger has

Tare-Functions: By pressing ´Tare´, the display will be set to 0. All measure-

value. When the tare function is activated, the arrow

´Tare´

appears in the display. To deactivate the tare function press

Activating/deactivating tare clears the max- and min-memories.

Zero-Point Adjust: (for gauge pressure sensors only) If there is no pressure

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 zeropoint
adjustment can only be made if the difference between 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. 15 seconds.

A zero-point adjustment can only be carried out if the difference

between the value on display is less than 500 digits!

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.

Differential pressure: Pressing ´Set/Menu´ shows the difference between

the measured values of Channel 1 and Channel 2
(DIF=CH1-CH2) in the lower display. Pressing it again will
hide it (only with the 2-channel version and when 2 sensors
are connected).
