INTRVL (SEC)
INTRVL
 
(SEC)
 specifies the interval in seconds between each
data sample that is collected. For example, if you want to
collect 99 samples and 
INTRVL=1
, it takes 99 seconds to finish
data collection. Enter values using the number keys. See the
CBR or CBL 2/CBL guidebook for more information about
interval limits.
 
UNITS
The results are displayed according to the 
UNITS
 specified. To
specify a unit measurement (
Temp
 or 
Sonic
 only), highlight the
one you want using the cursor keys, and then press b.
 
PLOT
You can specify whether you want the calculator to collect
realtime (
RealTme
) samples, which means that the calculator
graphs data points immediately as they are being collected, or
you can wait and show the graph only after all data points
have been collected (
End
). Highlight the option you want with
the cursor keys, and then press b.
 
Ymin and Ymax
To specify 
Ymin
 and 
Ymax
 values for the final graph, press
' to view the 
PLOT WINDOW
 screen. Use $ and # to
move between options. Enter 
Ymin
 and 
Ymax
 using the number
keys. Press - l to return to the 
DATA LOGGER
 options
screen.
 
DIRECTNS (Directions)
If 
DIRECTNS=On
, the calculator displays step-by-step directions
on the screen, which help you set up and run the data
collection. To select 
On
 or 
Off
, highlight the one you want with
the cursor keys, and then press b.
With the 
Sonic
 data collection probe, if 
DIRECTNS=On
, the
calculator displays a menu screen before starting the
application asking you to select 
1:CBL
 or 
2:CBR.
 This ensures
that you get the appropriate directions. Press 
1
 to specify 
CBL
or 
2
 to specify 
CBR
.
