3.9 REPETITIVE PRINTING
It is sometimes desirable to record pressure measurements at fixed
intervals of time. To print at fixed intervals, follow this procedure:
1.
Connect a printer as outlined in Section 3.8.
2.
Enter the number of seconds between readings.
3.
Press PRINT. The gauge will print out a reading at the specified interval.
4.
To cancel repetitive printing, press "-" then PRINT.
To interpret the meaning of the symbols printed, see Appendix III - "RS-232C
Serial Data Communications."
Most printers are equipped with a buffer which allows them to receive information
at high speed from the gauge, and print it at the slower speed of the printer.
Using repetitive print mode with a printer which is not equipped with a buffer
may cause a "Q-OFLO" message to be printed, indicating that the printer
cannot accept information at the rate it is being sent. There are three solutions
to this problem; either make the repetitive print interval longer, use a printer
equipped with a buffer, or set the communications baud rate on both the gauge
and the printer as slow as possible (300 baud, for instance).
