Options Setup
The Configuration menu lets you see how your system has been configured for your
application. You may change the PC's COM port, the sensor membrane, automatic data
acquisition rate, or the sensor calibration mode. You may also lock out the instrument's
CAL
button, or for calibration using a span gas, you may enter the span gas percentage.
The Troubleshooting menu includes a series of tests, permits the setting of the clock, and
enables a barometric pressure calibration routine.
Finally, the Help menu gives access to the Help file and allows the identification of the
WinLog97 program (version number and copyright date).
5.2 Instrument - PC connection
For the hardware connection of the instrument to a PC, see WinLog97 PC program installation
on page 21 .
The Configuration, Serial port menu lets you choose one of four serial communication ports,
as follows:
Usually, COM1 is used to connect to a mouse, so try
COM2
first. You may find that a separate SetUp
program supplied with your PC is necessary to activate
this port.
Click on OK to activate the selected port. If the port you
have selected here is adequate, the WinLog97 program
will return to the main menu. Otherwise, you will see an
RS232 ERRORS
message advising you to select
another port.
