TX IOB Parameter Name Unit Description
Y Y O2 %
Current oxygen concentration value (O2 %). The value should reflect
the last good O2 value if it is in the “Lock” state during calibration.
Y Y O2 Temp °C Current O2 sensor temperature.
Y Y CJC Temp °C Current cold junction temperature.
N Y Board Temp °C Current electronic temperature measured at the I/O board.
Y Y O2 Cell mV Raw mV value for O2 sensor.
N Y T/C Volt mV O2 T/C voltage.
Y Y Cell Imp ohm Cell impedance/sensor resistance measured.
Y Y Heater V Heater voltage.
N Y Bottle Pressure1 psi Gas 1 bottle pressure. (Valid if device is configured for HSPS autocal.)
N Y Bottle Pressure2 psi Gas 2 bottle pressure. (Valid if device is configured for HSPS autocal.)
N Y Cell Pressure1 in H2O
Cell pressure measured while applying gas 1. (Valid if device is
configured for HSPS autocal.)
N Y Cell Pressure2 in H2O
Cell pressure measured while applying gas 2. (Valid if device is
configured for HSPS autocal.)
Y Y O2 AO mA Analog output value represents the O2 concentration measurement.
N Y O2 AO % % Analog output percentage for O2 AO.
Y Y O2 Temp Max °C This is the highest O2 sensor temperature reached since last reset.

Y Y OP Mode --
Device operating mode:
PO=Power up; WU=Warm Up (analog output is railed);
NM=Normal operation; CA=Calibrating (analog output can
be tracking or locked at last good value based on
"AO Tracks" configuration); AL=Alarm detected
(recoverable); SF=Alarm detected (non-recoverable)
Y Y Active Alarms -- Current Alarms (See Section 4, Troubleshooting)
Y Y Device -- Alarm state
Y Y Failed -- Alarm state: On/Off
