Collecting Data
The second step involves collecting data in the TriCoder.
This is a good time to practice scanning. If you are not
familiar with scanning bar codes, see
Appendix C;
How to
scan a bar code
for details and suggestions. If you don’t
intend on using bar codes later, you can just enter the same data from the
keypad.
Pressing “0” at the PROGRAM NO.? prompt begins the data collection
process by displaying this prompt for the operator:
ENTER DATA _
For the purposes of this tutorial, we will use the sample bar codes as our
data. Upon scanning, the TriCoder will beep once and display the
following:
ENTER DATA
(
original prompt
)
00001
(
bar code #1
)
ENTER DATA
(
new data entry prompt
)
After scanning, the TriCoder displays the original prompt, then the data just
entered, then the new data entry prompt. For the tutorial, our second piece
of data will be 00002. Go ahead and scan sample bar code #2 or key in
00002:
00001
(
original data
)
ENTER DATA
(
2
nd
data entry prompt
)
00002
(
2
nd
piece of data entered
)
ENTER DATA
(
new data entry prompt
)
Continue to scan the sample bar codes or enter the data from the keypad.
The TriCoder display will scroll with each entry as shown immediately
above. As soon as you are finished entering all 10 bar codes, press the
END
key to exit
