5 Bases for measurement

5.1 Special functions

_

With the special functions that can be selected via the 

Configuration menu

, the

device can be optimised for special measuring tasks. After it is switched on, the
device starts up in standard measuring mode, the relevant special function is started
by pressing and holding the 

Function key

 for 4 s.

5.1.1  

NVLL 

Tare function

The special function 

FVNC

NVLL

 has been selected in the configuration menu.

The display can be zeroed by pressing the 

Function key

 for 4 s. If the tare function is

activated, 

NVLL

 blinks in the lower display. The tare function can be reset by pressing

the 

Function key

 again for 4 s.

NOTE

The tare function is independent of the zero point correction accessible via the set-

By pressing and holding the 

Function key

 for 4 s. the measurement with mean value

can be activated. Heavily fluctuating values arise particularly with dynamic pressure/
compression measurements in chimney draft tests of forced-air burners and, con-
sequently, conventional electronic manometers are not adequate for task. This spe-
cial function optimises the device for this application purpose. The different mean
value times of 2, 5 or 10 seconds can be selected depending on the requirement.

set by pressing and holding the

the special function must be switched in the configuration menu.
