Compared to the DSO 138, it has a smaller size and stronger functionality. It has upgraded a calibration function, improved test s, and supports direct updates through interfaces.

The DSO138 tested a maximum of 400VPP at 10 times the probe, but could not directly test the 220V mains voltage

The new version of FNIRSI 138pro can test 800VPP with a 10X probe, equivalent to 280V AC.
