Details
Up to 4 slots. Each slot can be programmed to return the
following parameters based on the Transmitter Variable
Code:
0 = % Oxygen
1 = Cell temperature
2 = Cell mV
3 = Cold junction
4 = Heater power (%)
5 = Rate of rise of cell temperature
6 = Cell impedance
7 = Cell impedance drift
8 = Recovery rate
9 = Test gas response time
10 = O deviation
2
11 = Cell calibration offset
12 = Cell calibration factor
13 = Cell zero offset
14 = Mains frequency
15 = Mains voltage
Sets the filter value for the % Oxygen reading.
Sets the % Oxygen range hi and lo values.
Bit 6 (Configuration Changed) of the Transmitter Status Byte
is reset by this command.
When a parameter has been changed via HART or the local
HMI the configuration changed bit is set.
For system troubleshooting purposes, current output 1 can
be set to a constant mA value.
Entering a value of 0 mA cancels the fixed output mode.
