If you have connected a temperature, humidity or absolute pressure probe their values are
accepted directly if you confirm the displayed value via under SPECIAL - P
ARAMETER - Temp.,
Humidity or Abs. pressure .
Note: If you work with standard density as set in the factory, the measurement error during
the velocity measurement can be as much as 10% of the measured value. If the
parameters are not correctly adjusted the error can increase considerably.
The density should be checked from time to time or print out the set parameters in addition to the
measured value:
Printing set parameters
You will get the following in the Main menu under PRINT - CONFIGURATION:
- Pitot factor
- Temperature
- Humidity
- Absolute pressure
- Density.
The set parameters are automatically printed every time. The Testo logo is also printed if the
attachable printer (part no. 0554.0570) is connected. Automatic printing of logo and parameter can
be switched on or off via PRINT-P
RINT LOGO/PARAMETER.
The following selection appears once the function button is pressed:
