Page 19 1 Print (Optional) Pressing the print function key will print the emissions data in the following format (see below). All temperature (Key 7 - Temperature) emissions (Key 8 - Emissions) and efficiency (Key 9 - Efficiency) data will be printed. If the probe is not attached correctly (Section 5.2) or the stack and intake thermocouples are not connected then the temperature data will not be printed.
