Measurement example using the BDD function
This is an example of setting and using the BDD function.
Description
Sent to the BT5525 from
the controller
Example of the BT5525 response
(1) Enable the BDD judgment
using the CC (charging)
voltage.
:BDD:CC:V ON
–
(2) Set the BDD judgment
threshold value using the
CC voltage to 2 V.
:BDD:CC:V:THReshold 2
–
(3) Query the BDD judgment
threshold value using the
CC voltage.
:BDD:CC:V:
THReshold?

2.0
(4) Enable the BDD judgment
using the CV (steady state)
voltage.
:BDD:CV:V ON
–
(5) Set the BDD judgment
threshold value using the
CV voltage to 0.5 V.
:BDD:CV:V:THReshold
0.5
–
(6) Query the BDD judgment
threshold value using the
CV voltage.
:BDD:CV:V:
THReshold?
␣␣
0.5
(7) Enable the BDD judgment
using the CV (steady state)
current.
:BDD:CV:I ON
–
(8) Set the BDD judgment
threshold value using the
CV current to 10%.
:BDD:CV:I:THReshold
10
–
(9) Query the BDD judgment
threshold value using the
CV current.
:BDD:CV:I:
THReshold?

10.0
(10) Enable the setting to end
the test if the BDD count is
1 or more.
:BDD:STOP ON
–
(11) Perform the test for
10 seconds.
:TIMer 10;:STARt

(12) Query the number of BDD
measured values saved in
the memory.
:BDD:COUNt?

(13) Query the BDD measured
values saved in the memory.

(1) (4) (7) Enable the BDD function at each measurement.
CC (constant current) charging is performed until the test voltage is reached after measurement
starts and a voltage fluctuation is detected. Once the test voltage is reached, measurement is
performed using CV (constant voltage) and fluctuations of the voltage and current are both detected.
(2) (5) (8) Set the BDD threshold value. A voltage fluctuation is set as a value (unit: V) and a current
fluctuation is set as a rate (unit: %).
(3) (6) (9) Query the BDD threshold value to check it.
(10)
Enable the setting to stop the test when the BDD count is 1 or more.
(12) (13) Query the BDD measured value stored in the instrument’s memory after the test completes.
The BDD count is 3, indicating that the instrument detected two current fluctuations and one
voltage fluctuation that exceeded the applicable thresholds value during CV operation. Voltage
fluctuations are output as a value (unit: V), while current fluctuations are output as a ratio (unit: %).
