Chapter 12

USB-A interface

The device has a USB-A interface. The corresponding port is at the top of the device. The interface is compatible with
USB 2.0 specification in high speed mode. The measuring device only supports the MASS STORAGE DEVICE class (USB
stick).

The measuring receiver software can read files from, and write files to, a USB stick using the FAT32 file system. A USB
stick is used to carry out firmware updates or to record measurement data (DataLogger).

We recommend using the original USB stick from the device manufacturer. The USB stick is included in delivery.
