The set point band is defined as the actual value of the set point plus or minus the
hysteresis value. The hysteresis value is fixed at 0.1% oxygen. Alarm action occurs if the
input value is above or below the set point band. If the input moves within the set point
band the last alarm action is maintained.
Alarm Set Point
The alarm set point can be set to any value within the oxygen range of 0.3% to 25.0%.
Retransmission Type
The retransmission output is assigned to the oxygen range.
Select the retransmission output current range required (4 to 20mA, 0 to 20mA or 0 to
10mA).
LOG Output
The retransmission can be assigned to give a logarithmic or linear output.
Select YES for Logarithmic, NO for Linear.
Retransmission Span
Select the required retransmission span value, in % oxygen units, from 5.25% to 25.00%.
Retransmission Zero
Select the required retransmission zero value, in % oxygen units, from 0.25% to 20.00%.
Test Retransmission
The instrument automatically transmits a test signal of 0, 25, 50, 75 and 100% of the
retransmission range selected above. The % test signal selected is shown on the upper
display.
Example: for a selected range of 0 to 20mA and 50% retransmission test signal, 10mA is
transmitted.
Alter Security Code
Set the security code to a value between 00000 and 199999.

Note. Electrical calibration is carried out prior to despatch and should not be altered.
However, if inaccurate or inconsistent readings are obtained, refer to the Electrical
Calibration Supplement for full calibration procedures.
