Retransmission Zero
Set the required retransmission zero value, in % oxygen units.
[0% to 20.00% (linear output)]
or
[0.01% to 0.25% (logarithmic output)].
Retransmission Span
Linear Output – Set the required retransmission span value, in % oxygen units.
The retransmission span value must be at least 5% above the retransmission
zero value.
[5% to 25.00%]
Logarithmic Output – The retransmission span is preset to two decades above
the zero value and cannot be adjusted. For example, if the zero is set to 0.2%,
the span is preset to 20.00% .
Hold Outputs
The retransmission and alarm outputs can be held to prevent inadvertent
operation during a test gas calibration sequence.
YES
Test Retransmission
The instrument 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 – when the
the Test Retransmission signal is set to '50%', the retransmission output value
is forced to 10mA.
Alter Security Code
[00000 to 99999]
Set the security code used to gain access to secure parameters – see
Section 7.4.
Alter Calibration Code
[00000 and 99999]
Set the code used to gain access to the oxygen calibration facility – see
Sections 7.1 to 7.3.
