8.2 CALIBRATION MODE FUNCTIONS

8.2.1 REFERENCE VOLTAGES

The calibration of the analogue inputs is based on the voltage of a temperature compensated voltage reference integrated circuit. There are 4 voltages generated from the standard reference voltage. They will vary by about 1% from one transmitter to another but can be trimmed by setting the actual voltages into CALIBRATION menu functions #1 to 4. These voltages should be measured and the reference voltage entries in the menu checked every year.

8.2.2 OUTPUT CHANNEL 1 AND 2 CALIBRATION

The output 4‐20mA calibration can be set either AUTOMATICALLY (default) or MANUALLY. If Auto Calibrated is selected the transmitter will go through an output calibration cycle when the power is turned on or when the AUTO CAL button is pressed in SETUP mode. This will divert the outputs back to the input and automatically set the 4mA and 20mA calibration.

If Manually Calibrated is selected then the 4mA and 20mA calibration must be set in the next two functions. For the full explanation see chapter 10.1.2.

8.2.3 AMBIENT TEMPERATURE CALIBRATION

The ambient temperature measurement is used as the cold junction temperature for the thermocouple measurements. Use an independent temperature sensor to measure the temperature inside the transmitter case near the screw terminal #1. Enter this temperature into the calibration function 11 by using the OPTION keys and then the ENTER key.

8.2.4 LOW OXYGEN CALIBRATION

The low oxygen calibration factors can be used to fine tune the oxygen calculation at low oxygen readings. It will not affect the measurement at 20.9%. They are included to allow oxygen probes made by other manufacturers to be used on a Teledyne Analytical Instruments transmitter. The default is 100% but can be set to between 80 and 120%.

8.2.5 TRANSMITTER OUTPUT SCALE

The transmitter outputs can be configured to either 4‐20mA or 0‐20mA. The two scaled outputs are capable of outputting 0‐24mA and will transmit over‐scale unless the over‐scale limit option is selected.

8.2.6 TRANSMITTER OUTPUT LIMITING

If the oxygen reading is invalid the output can be made to be set to 0mA, 4mA or 20mA. An invalid reading is when the probe temperature is below 650°C (1200°F) or the probe thermocouple has been detected as open circuit. The default is to set the output to 20mA but the function can also be disabled.

8.2.7 MAINS VOLTAGE DETECTION

The default setting for the 9060Z transmitter is that it will automatically detect the mains voltage and frequency in order to correctly drive the probe heaters. If there is any uncertainty in this detection system the voltage can be forced to 220‐240 or 100‐127, and the frequency can be set to 50 or 60Hz.
