DC 2000
PRO
The right
C I/O key
has two functions. Pressing it once cancels the current
menu option or an incorrectly entered value. Keeping it pressed switches OFF
the device after about three seconds.

The socket can take a hose with an internal diameter of 5–6 mm or, if the
design of the DC 2000
PRO
allows this, a DN 2.7-type rapid-action coupling.
Silicone hoses can perforate at overpressures greater than 1 bar, adding to
the leakage rate, so should not be used for these pressure ranges.
In Figure 2.2, the rear of the DC 2000
PRO
exhibits diffusion apertures for the
internal registration of
ambient humidity
(optional) and
temperature
. The
integrated temperature measurement also serves to compensate for tempera-
tures in the pressure sensor. When the device is used as a precision tempera-
ture sensor with extended measuring range (–19.9 °C to +99.9 °C) the exter-
nal combustion air temperature sensor A 500 (order no. 9605) or the external
combustion air probe A 500 (order no. 9611) with a 2 m cable can be used.
The measured data are read out of the logger and transferred to a PC via the
IR (infrared) interface (order no. 9631 serial or 9318 USB or Bluelink 500.)
