Temperature calibration must be performed by a qualified individual that has a
certified temperature calibration device. When the screen in above appears, connect
a J type temperature calibrator to the thermocouple connector input on the
instrument. Enter a lower-limit temperature value on the calibrator. Touch the Enter
Low Value parameter box shown above and then enter the correct temperature
value for the low data point using the touchpad at the right. The raw value is the
voltage signal read directly from the I/O hardware and it should change as the
calibration signal changes. When the low data point has been entered, press the
SAVE LOW VALUE button. The user can now enter the high data point on the
calibrator and then again on the touchscreen as before. The raw value should be
different for the low and high data points or there will be a computation error. After
the high data point has been established, press the SAVE HIGH VALUE button.
We recommend using a low value of room temperature and a high value of 400F or
near maximum operating temperature. The user can now vary the calibration signal
and see how the calibrated signal compares with that of the calibration device in the
VERIFY NEW CALIBRATION box. If the signals compare favorably, press the
SAVE button to save the calibration. The calibration values will be stored in a
configuration file and take effect upon saving and exiting the Instrument Setup
menu.
