COPYING DATA TO EXTERNAL MEMORY
When connecting an external memory device such as a Micro-SD card or a USB memory
device, the VLTS will identify it and display the free memory in it within 2 seconds. For

sensors, sampling date and time, values measured by the 4 sensors and the measurement
units. The file may be opened in Excel.
In Copy to mode, 2 files are created on the external memory. A configuration file in a TXT

20-17.DAT, which represents the date 11-27 -19 and the time 20:17. The DAT file contains
all the readings consecutively at the sampling rate. The data include: device name, sensor
names, sampling date and time, values measured by the 4 sensors and the measurement
