Calibration Method for CPEC310 Gas Analyzer





System startupBefore the unmanned automatic calibration function

It is necessary to set up according to the following steps





  1. Translate into EnglishSCRUB MODULEandCO2 Standard gas cylinderorDew point generatorConnect to the trachea separatelyVALVE MODULECorresponding interfaces.




  1. choice initial configuration--CO2 Spn Gas，inputCO2 Concentration value of standard gas.

  1. choiceinitial configuration--H2O Spn TDPEnter the set dew point temperature.




  1. Set parameters and paths through CR1000KDSystem Control--Const Table：

  1. Translate into EnglishCPEC310SCRUB, CHECK_ZRO, SET_ZRO, CHECK_CO2, SET_CO2set toTRUE；

  2. ZRO_SPN_INTV：Calibration cycle (days)Modify according to the requirements;

  3. ZRO_SPN_OFST：Calibration time (min)Set according to the requirements;

  4. TIME_ZRO_SPN：Ventilation duration (sec)Modify according to the distance between the gas analyzer and the host box.




  1. choiceRun Station—Auto Z/S on, set asTRUE.

After the above parameter settings are completed

The system can follow the set cycle

Implement unmanned automatic online calibration







Of course!

The system also supports calibration through manual methods
