4.1.6 Printing Test Results (Model 60 only)
During a combustion effi ciency test, the current test results can be sent to
a printer as follows:
1. Turn ON printer.
TIP: Refer to the printer's instruction manual for detailed operating
information. If not already done, set up the printer for 9600 baud,
DTR handshaking, and the same protocol as the analyzer (HP or
IrDA). Refer to Section 3.5.7 Selecting Printer Protocol.
2. Align the printer with the top of the analyzer as shown in Figure
4-1.
3. Begin printing by doing one of the following:
- If the pump is running, press the HOLD button twice.
- If the display has been previously frozen by pressing the HOLD
button, press the HOLD button only once.
