Gas concentration measurement error compensation method e.g. for oxygen gas, involves compares measurement value of specific time period, and preset value, to perform temperature dependent error compensation for following time period

摘要

The lowest or highest gas concentration measurement value evaluated by gas sensor (8) during specific time period (T1), is stored in the memories (69,69'). The stored value is compared with preset value, to perform temperature dependent compensation of gas concentration measurement error for following time period (T2). An independent claim is also included for electronic circuit arrangement for compensating gas concentration measurement error.
