The APPA 300 Series are a series of handheld multimeters with Optical RS232 (later USB) connectivity.

WARNING: The sigrok driver is implemented but untested and therefore marked "experimental"! If you have the device, please share your experience and report bugs.

Known compatible devices are the ISO-TEC IDM30x. It is assumed that the 207 is a desktop variant of the 303 and should be supported by the driver as well.
