DAC and APICONTeledyne API – Model T300/T300M CO Analyzer

Teledyne Analytical Instruments 180

7.1.11. HOLDOFF FEATURE

The DAS HOLDOFF feature prevents data collection during calibration operations and

at certain times when the quality of the analyzer’s CO measurements may not be certain

(e.g. while the instrument is warming up). In this case, the length of time that the

HOLDOFF feature is active is determined by the value of the internal variable (VARS),

DAS_HOLDOFF.

To set the length of the DAS_HOLDOFF period, go to the SETUP>MORE>VARS

menu (Section 5.8) and EDIT the “0) DAS_HOLD_OFF…” parameter.

To enable or disable the HOLDOFF feature for an individual channel, follow the

instruction shown in Section 7.1.4 then press:
