MMEMory:EXPort?
Description Export the readings in the reading memory and the current instrument configuration to
the default directory in the external USB storage device.
Explanation The default directory is \M300\data\<SN>\YYYYMMDD_hhmmss. Wherein, <SN> is
the instrument serial number, YYYYMMDD indicates the current date, and hhmmss
indicates the current time.
Two csv files are generated in the default directory, namely the instrument
configuration (config.csv) and readings (dat00001.csv).
The instrument configuration (config.csv) file contains the M300 model, serial
number and software version number, module and its version number in each slot;
interface settings as well as scan configuration. The reading (dat00001.csv) file
contains the number of scans, scan time and measurement readings of each channel.
Since this command is time-consuming, reading the return value will generate an
error when the timeout time is short. Therefore, we recommend that you adjust the
timeout time according to the export time or read the return value after the export
operation is finished. The export time is related to the number of readings and the
following table shows the relationship.

You can set the field separator in the exported files using the
MMEMory:FORMat:READing:CSEParator command.
Return
Format
The query returns 0 (no error) or 1 (error is generated) when the file export is complete.
If the query returns 1, use the SYSTem:ERRor? command to read the error information.
Example MMEM:EXP?
The query returns 0.
