Temperature test
▷ A temperature test is required on diaphragm gas
meters with temperature conversion BK..Te only.
▷ The accuracy of the temperature measurement
can be verified with this test.
▷ The temperature test can only be carried out in
Service mode.
CAUTION
To avoid damage to the unit:
– Comply with ambient temperature, see
page 15 (Technical data). Deviations from
the permitted ambient temperature will be re-
corded in the error memory.
▷ Temperature measurement accuracy, see
page 15 (Technical data).
 Install the diaphragm gas meter in a climatic
chamber.
 Activate Service mode – see page 5 (Service
mode).
 Change to the "Temperature" menu.
▷ The current gas temperature is displayed.
4 Close the climatic chamber.
5 Select an ambient temperature as a reference
value and bring the climatic chamber to this tem-
perature.
▷ To ensure there is also a uniform temperature
in the meter, we recommend starting the meter
air/gas flow during the temperature adjustment
phase.
▷ Ensure that temperature distribution remains
uniform and stable during the temperature
measurement.
6 Compare the measured value to the temperature
reference value.
▷ If required, several reference values can be
checked. In this case, repeat the test as of
point 5 .
