TSI Instruments 3022A User Manual

Computer Interface and Commands 8-7
The program is loaded on one 3.5-inch disk. To run the program,
first boot the computer and load BASICA
or a compatible BASIC
interpreter. To load the program, type <LOAD "TSICPC.BAS> and
then type <RUN>.
The program has self-explanatory, easy-to-use menus. The various
tasks performed by the program are explained in earlier sections of
this manual.
This program is intended as a reference guide to those who wish to
write their own software. It may be modified as desired. However,
TSI cannot support any user-written software except as illustrated
in this manual.
Note: The display nested under (3) Read Menu, (D) Read time,
counts and concentration, and (1) Start the measurement gives
two concentration measurements. The first is the concentration
that can be read from the front panel of the CPC. The second
is the averaged concentration over the time interval. It is
calculated by dividing the counts by the time and the flowrate:
