9060-Zirconia Analyser
The smoothing of the oxygen signal is an exponential function. If a factor of 5 is used, a
step change of input signal will take about 5 seconds to reach 63% of the change on the
output/display.
Range
1 to 20. Default setting is 5.
88. MODBUS™ Address
This function is used when networking of one or more transmitters back to a master
computer or data acquisition system is required. For more details on the functions of the
MODBUS™ see Section 2.12, and Appendix 6.
The valid range of MODBUS™ addresses is from 1 to 31. Any transmitter with zero
selected as the MODBUS™ address will have the MODBUS™ disabled, and the data log
function enabled.
For the connection details, see Section 3.15.
NOTE: If the MODBUS™ address is changed, the transmitter must be turned off and back
on for the address change to take effect.
Range:
0-31 Default setting is 0.

89. Reference Air Pump Cycle
The reference air pump will normally run all the time. However, if the inside case
temperature is greater than 35°C the pump will turn off for 30 seconds every minute to
reduce the case temperature and extend the life of the pump.
Where the ambient temperature is always greater than 35°C, the life of the pump can be
further extended by reducing the pump on time. This function allows the user to set the on
time of the pump over a 10 minute cycle.
Range:
1-10 Default setting is 10 (Always on)
Temperature >35°C Burst (Always on unless case >35°C)

90. Low Oxygen Calibration Factor, Sensor #1
The Teledyne zirconia oxygen sensors only require the sensor offset to be set. This
corrects the oxygen reading for any sensor offset at the 20.9% level (See Set-up 11 &12
for details). After setting the offset oxygen readings other than 20.9% will also be within
the rated specification for nearly all applications.
To allow zirconia probes made by other manufacturers to also be used on the Teledyne
transmitter, a correction factor can be entered to allow for oxygen reading much smaller
and much larger than 20.9% to be fine tuned.
For complete details of how to set the "Low Oxygen Calibration" see Section 2.9.
Range
90 to 110. Default setting is 100.
91. Low Oxygen Calibration Factor, Sensor #2
Follow the same procedure outlined in set-up 90 for calibration of sensor #2.
