Numerical Indication; Freezing Measurement Values - Ecom -DP Operating Instructions Manual

3. Numerical indication

If „Pressure Auto -> O by start" is set on
„YES" (Chapter 6.2), so the internal pres-
sure sensors should be flown with pres-
sure first after the switch-on of the in-
strument, as they are zeroed during
After switch-on, the specifications of the pressure sen-
sor will be displayed: denomination, measurement
range and connection seizure (+/-).
access to the measurement value menu.
1. Before making measurements, the instrument must have
adapted the ambient temperature!
2. Make sure, that the ambient temperature remains constant
during measurement!
3.1. Zeroing the internal pressure sensor
As the difference pressure sensor can drift because of
its sensitivity in the zero point (also by attaching to met-
al surfaces by magnetic holder), it is possible to reset
the zero point.
- Press <F2> (DP->0) to activate the function for zero
point correction of the pressure sensors.
- Press <F3> (DP1) to zero the value of the pressure
sensor 1.
- Press <F4> (DP2) to zero the value of the pressure
sensor 2.
- Press <F2> (ESC) to quit the menu.
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".
3.2. 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.
