About CMD5—Data Range Setup
CMD5 Operations
CMD5
lets you select the channel number, and raw collected or
processed data retrieved by a calculator. It also lets you select the
number of elements for list and matrix samples retrieved by the
calculator. The first element in the list must be a 5 to designate
CMD5
.
List Syntax
{5,channel,data_select,data_begin,data_end}
Note:
CMD5
parameters are ignored if the Data Type parameter is 3
(picture) in
CMD2
.
Channel Select
This parameter lets you select the channel from which to retrieve data
into the calculator. (Default:
0
)

L1
Selects the lowest active channel
CH1
(analog channel)
CH2
(analog channel)
CH3
(analog channel)
SONIC
(ultrasonic channel)
DIG IN
(digital input channel)
Selects the recorded time selected in
CMD3
Note: If this parameter is L1, you must have also selected Record Time
(absolute or relative) in
CMD3
; otherwise, you will get an E.52 error
message (page 57).
If absolute record time is selected in
CMD3
, the time returned to a
calculator is relative to the sample collected just prior to the first
sample. For example, if the Data Begin parameter is set to 100, the
recorded time retrieved will be relative to the recorded time of the 99th
sample.
The CBL only stores the relative record time and computes the absolute
time as each list or matrix is requested. If you need absolute time with
respect to some other point for your application (such as the first
collected sample), you can retrieve the relative time and compute the
absolute time on the calculator.
