The fuel can be selected. The fuel-specific coefficients and limits
can be set.
Apart from the pre-configured fuels, 10 more customer specific
fuels can be configured. Fuel parameter, see
www.testo.com/download-center (registration required).
In order to maintain the measuring accuracy of the
instrument one must choose or configure the correct fuel.
Correct representation of measuring results is only assured
if the threshold values for the ideal range of the
