The PeakTech 4390A is a 4000 counts handheld digital multimeter with RS232 connectivity.
This is a rebadged Metex M-3860M multimeter.
Note: This is not the same device as the PeakTech 4390, despite the very similar name.

RS232 cable:
Serial cable
See Device_cables#Metex_5-pin_RS232_cable (Version 2).
Protocol
See Multimeter_ICs#Metex_14-byte_ASCII.
The device sends 4 * 14 bytes. The first 14 bytes represents the main display and then the three sub displays from left to right (left, middle, right).
