N Y Prev Cal Imp Ohm Previous Cell Impedance. This is the sensor resistance that was calculated as a result of
previous successful calibration. There are ten calibration results. Index 1 is the most recent and
Index 10 is the least recent sensor resistance measured.
N Y Failed Slope mV/Dec Failed calibration slope.
N Y Failed Const mV Failed calibration constant.
Y Y Cal Result mV Calibration result.
N Y Delta Imp -- Delta impedance since last calibration.
N Y Cal Step -- This represents the step of the calibration cycle is in.
N Y Time Remain sec Time remaining in the present calibration cycle state.
Y Y O2 Slope mV/Dec O2 slope. This is the slope value that will be used to calculate O2.
Y Y O2 Const mV O2 constant. This is the constant value that will be used to calculate O2.
N Y T90 Filter sec Analog output T90 time. It represents the time to take a step change in oxygen to reach 90% of
the final value at the filter output.
N Y O2 Cell Ref % O2 sensor reference gas percentage. It allows using a sensor reference gas other than air.
N Y O2 Temp SP degC O2 sensor temperature set point. It allows measurement of oxygen with an elevated sensor
temperature. (0=736 degC set point; 1=834 degC set point)
N Y Features -- Advanced software features.
(0=Stoichiometer; 1=Programmable Reference; 2=Elevated Temperature)
Y Y O2 URV % Primary variable (O2%) upper range value.
Y Y O2 LRV % Primary variable (O2%) lower range value.
N Y O2 AO Range -- Analog output polarity. (0=4-20 mA; 1=20-4 mA)
Y Y O2 Alarm Level -- O2 alarm level. (0=3.5 mA; 1=21.1 mA)
N Y Alarm Relay 1 -- Alarm Relay 1 mode.
(no alarm; unit alarm; low O2 alarm; low O2/unit alarm;
Cal recommended; Cal recommended/unit alarm; low O2/Cal recommended;
low O2/unit alarm/Cal recommended)
N Y Alarm Relay 2 -- Alarm Relay 2 mode. (no alarm; unit alarm; low O2 alarm; low O2/unit alarm
Cal recommended; Cal recommended/unit alarm; low O2/Cal recommended;
low O2/unit alarm/Cal recommended; Heater relay)
N Y Low O2 Alm % Low O2 alarm threshold.
N Y Hi Temp Alm % High temperature alarm threshold.
N Y AO Tracks -- Analog output track O2 sensor measurement during a calibration. (No, Yes).
N Y Auto Cal -- Enable/disable automatic calibration.
No = Set to Manual calibration mode.
Yes = Set to Automatic calibration mode.
N Y Start On CalRec -- Start automatic calibration on Cal Recommended state. (No, Yes)
Y Y Cal Gas 1 % Test Gas 1 value. This is the actual value of the gas being applied during the Test Gas 1 phase
of a calibration.
Y Y Cal Gas 2 % Test Gas 2 value. This is the actual value of the gas being applied during the Test Gas 2 phase
of a calibration.
Y Y Gas Time sec Test Gas application time. This is the length of time test gases are applied to the O2 probe
during low or high Test Gas phase of a calibration.
Y Y Purge Time sec Test Gas purge time. This is the length of time before the output will be returned to the process
reading after a calibration.
N Y Cal Interval hr Automatic calibration interval. The number 9999 disables the automatic timed calibration.
N Y Next Cal Time hr Time remaining until the next automatic periodic calibration. The number 9999 disables the next
automatic timed calibration.
Y Y T EE Val -- Transmitter board nonvolatile memory diagnostic.
N Y IO EE Val -- I/O board nonvolatile memory diagnostic.
Y Y Version -- Software version number for the Transmitter.
N Y Version -- Software version number for the I/O board.
Y Y T Restart Cntr -- Software restarts count for the Transmitter.
N Y IO Restart Cntr -- Software restarts count for the IO board.
Y Y Alarms -- Current Alarms (See section 5, Troubleshooting, ”Alarm Indications”.)
