the max- & 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 deviation
(and device is operated under steady conditions), a permanent zero point
adjustment can be carried out.
To carry out the adjustment press ´Tara´ for approx. 5 seconds.
(Please note: A zero-point adjustment can only be carried out if the
difference between the value on display and the value calibrated on site is
less than 2%! E.g. for the measuring range of 0 ..+25.00mbar,
=>zero-point adjustment up to 0.50mbar possible)
To recall the manufacturers’ calibration press ´Tara´ for approx. 7 seconds.
Please note: If a zero-point adjustment was carried out, this will be signalled
by the short displaying of „NuLL Corr“ when switching on
the device.
Differential press**:
Pressing ´set/Menu´ shows the difference of channel 1- channel 2 (CH1-
CH2) in the secondary display. Pressing it again will undo it (**only when
2 channel version and 2 sensors connected).
