3.4 Temperature measurements

Temperature measurements are activated when the ± key in the Signal Mode
menu is repeatedly pressed until the text "Temperature" appears with the
unit of measurement "°C". Again pressing the ± key switches to the unit of
measurement "°F". The ENTER key confirms the selected measuring mode
and returns to the display.
An external temperature sensor can be connected at any time. In this case
the device switches automatically to the external sensor.
For precision measurements, the sensor's five-digit calibration number (e.g.
cal. no. 10208) should be entered under TLOff in the Setup menu. This cali-
bration number is printed on a metal foil provided with every combustion air
temperature sensor. When no external sensor is connected, the temperature
of an internal sensor is displayed that also serves to compensate for the
temperature of the pressure and the humidity sensor signals. When therefore
ambient temperatures and humidities are constantly measured the housing
should not be exposed to direct sunlight or heat radiation.
Figure 3.4 shows the wall temperature sensor order no. 3392. The integrated
magnet serves to secure a DC 100
contains a special-purpose wall temperature sensor that facilitates perma-
nent, non-destructive adhesion between the device and problem surfaces
(e.g. mouldy wallpaper). This adhesion is ensured by replaceable, double-
sided adhesive strips (order no. 3393) of great adhesive strength.
The Wöhler DC 100
also determine exhaust gas temperatures up to 250 °C (for short periods up
to 300 °C) of firing plant. This requires its own menu item, which is explained
in detail under Section 6.
