2.1 Use
The testo 440 is used for measuring climate-related parameters. The testo 440
is particularly suitable for comfort level measurements for remove the
workplace evaluation and disturbance measurements in and at air conditioning
systems.
The instrument is only to be used by qualified personnel and must not be used
in potentially explosive atmospheres!
The testo 440 is supplied with inserted batteries. The batteries are
secured by a battery safety strip.

For humidity adjustment, the measurement parameter of the connected probe
is adjusted to the reference value at the two standard adjustment points 11.3%
RH and 75.3% RH; any deviations between the measuring value and the
nominal value are minimised across the entire measuring range.
The Testo calibration set provides a reference value to calculate the offset for a

3.5.8 K-factor volume flow application [K-Factor
Volume Flow]
The testo 440 can determine the volume flow by measuring the reference
resistance and input of the K-factor. This allows the testo 440 to remain
connected to the air outlet during adjustment work and the changes in volume
flow can be read directly on the display.
The application menu can only be accessed with testo 440 dP or used

in combination with a testo 510i with Bluetooth
.
This process for determining volume flow can always be used when there are
appropriate specifications available from the component manufacturer. In line
with these specifications, the differential pressure is measured at a position
specified by the manufacturer or supplier. The volume flow is determined from
the differential pressure via a component-specific K-factor using a
mathematical equation.
