MODE MEANING
DIAG
One of the analyzer’s diagnostic modes is being utilized (See Section 6.13).
M-P CAL This is the basic, multi-point calibration mode of the instrument and is activated by pressing
the CAL key.
SAMPLE
Sampling normally, flashing indicates adaptive filter is on.
SAMPLE A Indicates that unit is in SAMPLE Mode and AUTOCAL feature is activated.
SETUP
1
SETUP mode is being used to configure the analyzer (CO
2
sampling will continue during this
process).
SPAN CAL A
Unit is performing span cal procedure initiated automatically by the analyzer’s AUTOCAL
feature.
SPAN CAL M
Unit is performing span cal procedure initiated manually by the user.
SPAN CAL R Unit is performing span cal procedure initiated remotely via the RS-232, RS-4485 or digital i/o
control inputs.
ZERO CAL A
Unit is performing zero cal procedure initiated automatically by the analyzer’s AUTOCAL
feature.
ZERO CAL M
Unit is performing zero cal procedure initiated manually by the user.
ZERO CAL R Unit is performing zero cal procedure initiated remotely via the RS-232, RS-4485 or digital I/O
control inputs.

G.4
Finally, the various CAL modes allow calibration of the analyzer. Because of its importance, this mode is
described separately in Chapter 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 CO
2
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).
6.2.1. Test Functions
A series of test functions is available at the front panel while the analyzer is in SAMPLE mode. These
parameters provide information about the present operating status of the instrument and are useful during
troubleshooting (Section 11.1.2). They can also be recorded in one of the iDAS channels (Section 6.7) for data
analysis. To view the test functions, press one of the <TST TST> keys repeatedly in either direction.
