6.4.1. ADJUSTING THE A-REF MODE CYCLE TIME

The auto-reference measurement feature is initiated by the M300EU at regular intervals (see Section 10.1.1). It is triggered by the timer feature of the analyzers ACAL system, which uses the instrument’s internal clock.

All M300EU analyzers are shipped from the factory the ACAL system enabled (even on instruments without calibration valve options installed) and the first ACAL sequence already programmed and activated with the DELTA TIME parameter set for 4 hours (for a more detailed discussion of the ACAL system see Section 7.7 of the M300E/EM Operators Manual).

This interval time can be changed to fit the specific application in which the M300EU is being used. To change the A0REF interval, press:
