Analyzer Operating Modes
MODE
DIAG
One of the analyzer's diagnostic modes is being utilized (See Section 4.13).
M-P CAL
This is the basic, multi-point calibration mode of the instrument and is activated by pressing
the CAL button.
SAMPLE
Sampling normally, flashing indicates adaptive filter is on.
SAMPLE A
Indicates that unit is in SAMPLE Mode and AUTOCAL feature is activated.
SETUP mode is being used to configure the analyzer (CO
SETUP
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.
4.2. SAMPLE MODE
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).
68
The Mode field of the front panel display indicates to the user which operating
mode the unit is currently running.
Besides SAMPLE and SETUP, other modes the analyzer can be operated in are:
Finally, the various CAL modes allow calibration of the analyzer. Because of its
importance, this mode is described separately in Section 5.
This is the analyzer's standard operating mode. In this mode the instrument is
analyzing the gas in the sample chamber, calculating CO
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.
