Model GFC7000TA Carbon Dioxide Analyzer

Besides SAMPLE and SETUP, other modes the analyzer can be operated in are:

Table 6-1: Analyzer Operating modes

MEANING

One of the analyzer’s diagnostic modes is being utilized (See Section 6.13).

This is the basic, multi-point calibration mode of the instrument and is activated by pressing the CAL key.

Sampling normally, flashing indicates adaptive filter is on.

Indicates that unit is in SAMPLE Mode and AUTOCAL feature is activated.

SETUP mode is being used to configure the analyzer (CO2 sampling will continue during this process).

Unit is performing span cal procedure initiated automatically by the analyzer’s AUTOCAL feature.

Unit is performing span cal procedure initiated manually by the user.

Unit is performing span cal procedure initiated remotely via the RS-232, RS-4485 or digital i/o control inputs.

Unit is performing zero cal procedure initiated automatically by the analyzer’s AUTOCAL feature.

Unit is performing zero cal procedure initiated manually by the user.

Unit is performing zero cal procedure initiated remotely via the RS-232, RS-4485 or digital I/O control inputs.

1The revision of the Teledyne Instruments software installed in this analyzer will be displayed following the word SETUP. E.g. “SETUP G.4”

Finally, the various CAL modes allow calibration of the analyzer. Because of its importance, this mode is described separately in Section 7.

6.2. Sample Mode

This is the analyzer’s standard operating mode. In this mode the instrument is analyzing the gas in the sample chamber, calculating CO2 concentration and reporting this information to the user via the front panel display, the analog outputs and, if set up properly, the RS-232/485/Ethernet ports.

NOTE

A value of “XXXX” displayed in the CO2 Concentration field means that the M/R ratio is invalid because CO2 REF is either too high (> 4950 mVDC) or too low (< 1250 VDC).
