Saving, collating, and acquiring measured values (logging function)
You can save the measured values for each integral time that has been set. The measured values that have been
saved can be read for each individual channel, voltage, and current.
Up to 15,000 data points can be saved. The saved data uses a ring buffer configuration, so when the maximum
number of data points is exceeded, the oldest data is overwritten.
In the following cases, the saved data is deleted.
•
When logging starts
•
When the instrument is initialized (
＊
RST )
•
When a self-test is performed (
＊
TST? )
In the following cases, logging stops automatically.*
•
If the measurement conditions are changed
→
Execute logging again after finalizing the setting conditions.
•
Once the maximum time (12 hours from the start of logging) has elapsed (if logging was started without setting a
logging time)
•
If
＊
CLS is sent
* Changing the output voltage does not cause logging to stop
Starting/stopping logging
1
Start logging.
(
:DATA:STATe 1 )
2
Stop logging.
(
:DATA:STATe 0
)
Loading logging data
1
Output voltage logging data.
(
:DATA:VOLTage? <Channel number>,<Date count> )
2
Output current logging data.
(
:DATA:CURRent? <Channel number>,<Date count> )
If no data count is specified, all data will be returned.
