For example, if
BATTery:DATA:DATA? "VOLT, CURR"
is sent, the subsequent
BATTery:DATA:DATA? "MODE"
command will not return the current and voltage information. You
can get additional buffer data by sending the command
BATTery:DATA:DATA:SELected?
.
When specifying buffer elements, you can:
Specify buffer elements in any order.
Include up to 12 elements in a single list.
Repeat elements as long as the number of elements in the list is less than 12.
Use a comma to separate multiple elements for a data point.
Use quotation mark to enclose all the elements.
The options for
<bufferElements>
are described in the following table.
Options
Description
Example
VOLTage
The voltage value
+4.01
CURRent
The current value
+8.034562E-03
SOC
Value of State of charge, only available in SIMulator mode
95.50
RESistance
Internal resistance value in SIMulator mode; ECR value in TEST
mode.
1.52
AH
Actual A-H data only available in TEST mode.
+1.040727E-4
UNIT
Unit for measurement reading, source value, time stamp, and
reading number.
‘mA’, ‘s’ and ‘RDNG#’
MODE
Output state
CC,CV or OFF
DATE
The date when the data was generated
07/01/2013
TIME
The time when the data was generated
19:21:36.2553
TSTamp
The date and time when the data was generated
07/01/2013
19:21:36.2553
RELative
The relative time when the data was generated
+4.00
RSTamp
The relative stamp time when the data was generated
00:00:10.0126
RNUMber
Reading number indicates the index that the point in trace buffer. 0001
If you include SOC in
<bufferElements>
in battery test or AH measurement in battery simulator,
error 709, "buffer elements not supported in this mode," occurs.
Example
:BATT:DATA:DATA? "SOC,UNIT,REL"
The values of SOC, UNIT, and REL are returned.
