Manual IR Target Calibration Process

The Product is tested and calibrated with the tests outlined below in the sequence indicated,
see Table 8. Details to do each of the tests can be found in the subsequent section of this
document.
Many tests that use the same nominal set-points may be done sequentially as noted. For test
specifications, durations, soak times, and other detailed information, refer to the specification
tables in the Operators Manual.
All temperature tests are to be done in °C. Before you start any tests, make sure the system
temperature units are set to °C.
