SYS, IF
[RESET] : The settings of the instrument other than the communication settings and panel
are initialized.
LAN: To change the LAN settings, press [Reflect]. The instrument's LAN settings will not be
changed until [Reflect] is pressed; if a LAN connection has been made, it will be
reconnected.
Some functions cannot be set from the application.
INFO
Information on this instrument can be checked.
Obtains error information from the instrument.
For details on various errors, refer to the
":SYSTem:ERRor?" command page in the instrument's
instruction manual.

Revision 02

Various Tools
The following windows open from [Tool] on the top toolbar.
When the window is closed, it returns to the original screen.
The instrument will be synchronized with the instrument at that time.
Command test
Send and receive arbitrary commands.
Backup
Backs up the instrument's settings and saves a
dedicated settings file.
Check the items to be backed up and click [Backup]
to open the folder selection screen. When "Complete
Backup" is displayed, the backup is complete. If
multiple PANELs are set up, it may take some time.
Restore
Restore the instrument's settings from the dedicated
settings file created by the above backup.
Press [File] and select the backup file from the
folder.
Press [Restore] to execute the restoration, which is
complete when "Complete Restore" is displayed. If
multiple PANELs are set up, it may take some time.

BDD Analysis
BDD Analysis
Insulation resistance test is performed, and when the test stops, monitor voltage and current values
(reference values) from the start of the test are acquired, displayed on the data grid, and waveforms
are displayed on the graph.
Waveform data can be saved as CSV. (Note that this is different from the actual detection waveform
of the BDD function.)
Overview of Main Screen
When this application is launched, it synchronizes with the settings of this instrument.
When the screen settings are changed, the settings of this unit are automatically changed as
well.
You can set up and check the instrument.
Displays monitor data and BDD data acquired
after the test.
Press the button to perform the test.
Display a graph of monitored data
and a list of test results.

Revision 02
9
SETTING
Graph setting
Sets the number of waveforms sampled.
Sets the degree to which sampled waveforms
are thinned out. Larger values result in lower
resolution, but allow acquisition of waveforms of
longer duration.
The recording time with the above settings is
shown.
If checked, the voltage and current graphs are
displayed separately.
BDD setting
Enable BDD setting, set threshold
CCV: Detects V in CC (charging) state
CVV: Detects V in CV (steady) state
CVI: Detects I in CV (steady) state
When turned ON, the test is stopped when the
BDD count reaches 1 or more.
TEST
When checked, the test status of this instrument is
monitored; check this box if you want to control the
test with EXT I/O. The operation of this instrument
will not be possible because it will always be in the
remote state (RMT). Uncheck the check box if you
want to operate the instrument.
Displays the test status of the instrument.
IDLE: Waiting
TEST: Testing
DISCHARGE: Discharging
INTERLOCK: Waiting at interlock
Displays measurement results.
Displays the number of BDD
counts and their breakdown.

Revision 02

BDD data / MONITOR data
After the test STOP, it is read from the
instrument and the display is updated.
It can be saved as CSV by [SAVE].
Vmoni and Imoni are reference values.
BDD data displays the result when BDD
COUNT is 1 or more, and the unit of BDD value
is [V] when Type is CCV or CVV, and [%] when
CVI.
Note that the % of CVI is a percentage of the
BT5525's own reference value and cannot be
converted to a current value.
Graph / TEST data
Graph
Displays monitor value
waveforms of voltage and
current.
Displays the detection time and
magnitude of BDD as dots with
bars.
Move, zoom in/out, and copy
images on the graph by mouse
operation.
Check boxes allow you to switch
between showing/hiding the
waveforms and fixing the axes.
TEST data
Lists the test results.
For details, refer to the
":MEASure?" and
":CONTactcheck:CAPacitance?"
command pages of the instrument's
user manual.

Revision 02

Option
The [Tool] on the top toolbar opens the [Option] window.
Auto save function
At the end of the test, the checked items
are automatically saved in CSV format. If
none of the items are checked, the file will
not be automatically saved.
Enter the location to save the CSV file.
Click [OK] to save the settings and apply
them from the next test.
The file name to be saved automatically changes depending on the data checked.
File name ：yyyy-MM-dd_HH-mm-ss_auto_xxxx.csv （xxxx is the type of storage and number
of data）
Date and time the file was saved, information.
Measurement Setting
Saves when SETTING is checked.
TEST result
Saves when TEST data is checked.
BDD data, MONITOR data
If either BDD data or MONITOR data is
checked, it will be saved.
If both BDD data and MONITOR data
are checked, both data are combined
and sorted by Time and saved.

Application acceleration
Checking the option speeds up the
operation of this application. If you
have a lot of data you want to
auto-save and the test interval is
short, etc., and data cannot be read out
in time, please try speeding up the
process.
