Measuring

This chapter describes the steps that are required to

perform measurements with the product.

²

Taking aa m

measurement: 



The instrument is switched on and is in measurement
view.

Place the measuring instrument in the position in
which the measurement is to be made (Usage
position).
The measurement values can be falsified by a change
in the position of the measuring instrument. After
zeroing, the position of the measuring instrument
must not be changed. Carry out zeroing before every
measurement in order to compensate faulty
positioning or long-term zero-point drift. Zeroing is
only possible in a range of 0...25% of the measuring
range.

Carry out zeroing with open pressure connections:
press .

Attach pressure hoses to the pressure system or
position the Pitot tube, and read measurement values.

²

Holding tthe rreading, ddisplaying tthe m

maximum/minimum

value: 

The current pressure/flow measurement value can be
fixed. The maximum and minimum values of the 
parameters pressure and flow (since the last time the
instrument was switched on) can be displayed.

i

Press 

several times until the desired value is

displayed.
- The following are displayed in turn:

· Hold: the recorded reading
