5. Numerical indication
After switch-on, the specifications of the pressure sen-
sor will be displayed: denomination, measurement
range and connection seizure (+/-). Press <OK> to
access to the measurement value menu.
5.1. Zeroing the internal pressure sensor
Please remember not to flow the pressure sensors
with pressure during the zeroing procedure.
As the difference pressure sensor can drift because of
its sensitivity in the zero point, it is possible to reset the
zero point.
- Press <F4> (

P1) to zero the value of the pressure
sensor.
Different functions can be called up with the function
key <F1>. The current seizure of the other function keys
(<F2> - <F4>) is shown on the display. Press one time
<F1> to display the functions „Hold“, „Min/Max“ and
„Print“.
5.2. Freezing of measurement value
- Press <F2> (Hold) to „freeze“ that measurement value
displayed at the time the key is pressed (active function
= Hold indication blinks).
- Press again <F2> (Hold) to quit the „freezing“ and the
current value will be displayed.
1. Before making measurements, the instrument must have
adapted the ambient temperature!
2. Make sure, that the ambient temperature remains constant
during measurement!
If „Pressure Auto -> O by start“ is set on
„YES“ (Chapter 8.2), so the internal pres-
sure sensor should be flown with pres-
sure first after the switch-on of the in-
strument, as they are zeroed during
said switch-on procedure.
