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.

Electrical Calibration
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.
