Teledyne API – Technical Manual - Model 300E Family CO Analyzers Basic Operation

6.BASIC OPERATION

The M300E/EM Analyzer is a computer-controlled analyzer with a dynamic menu interface that allows all major operations to be controlled from the front panel display and keyboard through user-friendly menus (a complete set of menu trees is located in Appendix A of this manual).

This section includes step-by-step instructions for using the display/keyboard to set up and operate the M300E/EM Analyzer's basic CO measurement features and functional modes.

6.1.OVERVIEW OF OPERATING MODES

The M300E/EM software has a variety of operating modes. Most commonly, the analyzer will be operating in Sample Mode. In this mode a continuous read-out of the CO concentration is displayed on the front panel. If the analyzer is configured to measure more than one gas (e.g. CO along with O2 or CO2) the display will cycle through gas list.

While in SAMPLE mode calibrations can be performed and TEST functions as well as WARNING messages can be examined. If any of the analyzer’s analog outputs are enabled, the current concentration value will be available at the analog output connector.

The second most important operating mode is SETUP mode. This mode is used for performing certain configuration operations, such as programming the iDAS system or the configurable analog output channels, or setting up the analyzer’s serial communication channels (RS-232/RS-485/Ethernet). The SETUP mode is also used for performing various diagnostic tests during troubleshooting.

EXPLANATION

Sampling normally, flashing text indicates adaptive filter is on.

Indicates that unit is in Sample Mode while AUTOCAL feature is active (Internal Span Only). This is the basic calibration mode of the instrument and is activated by pressing the CAL key.

SETUP mode is being used to configure the analyzer. The gas measurement will continue during this process. The revision of the M300E/EM firmware being run will appear after the word “SETUP”

Unit is performing ZERO calibration procedure.

Unit is performing LOW SPAN (midpoint) cal check procedure. Unit is performing SPAN calibration procedure.

One of the analyzer’s diagnostic modes is active (Section 7.3).

[type:]

1A: Initiated automatically by the AUTOCAL feature (Internal Span Only).

2M: initiated manually by the user via the front panel controls.

3R: initiated remotely through the COM ports or digital control inputs.
