Calibration - TFA Dostmann 35.1023 Manual De Uso

Minimum/Maximum Selection
In this mode the mimimum or maximum values can be arbitrarily set by use of the
„Min/Max" key. The key functions as well as the functional sequences are identical
to the ones in Item Minimum/Maximum Function above. If desired, it is this way
possible to either firstly set all minimum values, followed by all maximum values or
immediately set all assigned minimum and maximum values to each respective
measuring point. Only one maximum value can be set for the wind strength. In
order to enter this value a switch from Min to Max must be performed.
Setting of Values
By use of the "+" and "–" keys the desired numerical values can now be set. By
holding the keys down, the device will automatically count up or down.
There is the additional possibility to speed up the counting by a factor of 10 by
simultaneously pressing the „Fast" key and either the „+" or the "–" key.

12. Calibration

All one time settings will be performed in Calibration Mode. This applies to the
Altitude Correction for the Barometric Air Pressure and the Calibration of the Rain
Volume Sensor as well as the setting of the desired Units for Air Pressure and Rain
Volume. In case of a faulty DCF-77 reception the time and date can also be set in
Calibration Mode. Further, if desired, the addresses of the Indoor Sensor to be
received, of the Wind Sensor and of the Rain Volume Sensor can be changed in
this mode.
The Calibration Mode can be entered by simultaneously pressing the (←), "Calibr."
and (→) keys. The respective display section can then be reached by use of the (←)
and (→) keys.
Setting of the Altitude Correction for the Barometric Air Pressure
After selecting the air pressure display section the altitude of your location with
regard to sea-level (H.a.SL – Height above Sea-Level) can directly be entered in
Meters (values from 0 to 1999 m possible) by use of the „+" and „–" keys and
possibly the „Fast" key. The setting of display units in hPa or mm is of no significance
for the Altitude Correction for the Barometric Air Pressure.
By pressing the „Store" key the set value is stored and the display will return to the
normal operating mode.
Calibration of the Rain Volume Sensor
Note!
The Rain Volume Sensor by design and manufacturing already offers a very
high accuracy and will for normal operation not require any special calibration.
Calibration may only be necessary for extremely high accuracy demands.
