  • Page 21 EC900 Series Operation Manual V4.7 If the auto-calibrate option is fitted, every x hours the calibration gas will automatically be fed to the measuring cell and after a few minutes the analyzer will self calibrate. Acd is set in hours.
  • Page 22 EC900 Series Operation Manual V4.7 The factory configuration password is 1234. Be sure to make a note should you want to change the password. Should the password be lost then the password 1111 will always gain entry. ALHLD Should the instrument be configured with alarms and automatic calibration then with this function the alarms can be suppressed for the duration of the autocal and for a further five minutes until the process settles down to equilibrium.

  • Page 23: Calibration

    EC900 Series Operation Manual V4.7 13.0 CALIBRATION Calibration should be carried out using a gas which is in the same range as the gas that is being analysed. For applications in the percentage range, the calibration may be carried out using atmospheric air.

  • Page 24: Calibration With Certified Gas

    EC900 Series Operation Manual V4.7 13.2 Calibration with Certified Gas EC9x0 EC9x1 EC9x2 Connect the certified gas to the sample port ensuring the same pressure as the sample gas, in order to obtain the same flow rate as the sample gas, allow the reading to stabilise.

  • Page 25: Automatic Calibration Option

    EC900 Series Operation Manual V4.7 13.3 Automatic Calibration option Automatic calibration can be initiated in two different ways. Either automatically after a pre- determined interval, or initiated by a control signal. 1. Connect the certified gas to the ‘cal gas’ connection on the rear panel of the analyzer or appropriate valve connection if using remote Autocal.
  • Page 26 EC900 Series Operation Manual V4.7 The instrument will only tolerate a certain level of adjustment. If the analyzer reads 4.9ppm and the certified bottle is 12.6ppm, the analyzer will reject the input of a value of 12.6ppm because it considers the error to be too large. Something else is almost certain to be incorrect. Ensure the sample from the bottle is at equilibrium and there are no leaks in the connection from the certified gas cylinder to the instrument.
