9. PRINTING DATA
WARNING: - To operate correctly there must be a clear line of sight between
the Infrared Window on the instrument (see 3.3) and the Infrared Window on
the IR Printer (see Printer instructions). Place the printer so it is no closer
than approximately 6 inches from the analyzer.
1. Press the Print Key once
'rEAL' and “Stor’ will be displayed and ‘rEAL’ will be flashing.
Selecting ‘rEAL’ will cause the 708 to print the test data currently on the
display (real time data). Selecting ‘Stor’ will cause the 708 to print data
stored in memory. Use the Up and Down Arrow Keys to select the desired
print mode and press the Scroll/Enter Key.
REAL Print Mode - If rEAL print mode is selected, the analyzer will dis-
play ‘Wait’ ‘out’ and bars will change position on the LCD until printing is
complete.
After printing is complete, ‘End’ will be displayed and ‘YES’ (or ‘no’) will
blink. Selecting ‘YES’ will return the 708 to normal operation, selecting
‘no’ will return the 708 to the print selection screen so you can print
again. Use the Up and Down Arrow Keys to make the selection and press
the Scroll/Enter Key.
STOR Print Mode - If Stor mode is selected, 'Addr' will be displayed on
the top line along with 'SA ' and a location number from 0 to 9 will be
flashing on the screen. Select the required address location that you wish
to print data from by pressing the Up and Down Arrow Keys and press
the ‘Scroll/Enter’ Key. The analyzer will display ‘Wait’, ‘out’ and bars will
change position on the LCD until printing is complete.
After printing is complete, ‘End’ will be displayed and ‘YES’ (or ‘no’) will
blink. Selecting ‘YES’ will return the 708 to normal operation, selecting
‘no’ will return the 708 to the print selection screen so you can print
again. Use the Up and Down Arrow Keys to make the selection and press
the Scroll/Enter Key.
Combustion and pressure/draft printouts must be performed separately.
Perform a combustion test and save the data. Perform a pressure/draft
test and save the data in a different address. Print each address sepa-
rately.
