2.3 Measurement Ranges and Accuracies
All data relative to concentration accuracies are referred to an instrument operating at a constant temperature
within the correct operating range (-5°C .. +45°C), being in operation for at least 15 minutes, powered by its
internal battery and after completion of auto-zero procedure.
Notes: (1) The maximum CO
2
value displayed depends on the type of fuel.
(2) Stated precision includes error of the external sensor RTD Pt100 class A DIN 43760 (1980).
(3) Stated precision includes error of the external sensor type K thermocouple class 1 IEC584.
(4) Pressures greater than 750 hPa may permanently damage sensors or impair their characteristics.
