Command

No.

Description

Details

Read Transmitter
Variables

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

11 = Cell calibration offset

12 = Cell calibration factor

13 = Cell zero offset

14 = Mains frequency

15 = Mains voltage

Write Primary Variable
Damping Value

Sets the filter value for the % Oxygen reading.

Write Primary Variable
Range Values

Sets the % Oxygen range hi and lo values.

Reset Configuration
Changed Flag

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.

Enter / Exit Primary
Variable Current Mode

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.
