The Metex M-3850M is a 4000 counts true rns, handheld digital multimeter with RS232 connectivity.
Hardware
RS232 cable:
- See Device_cables#Metex_5-pin_RS232_cable (version 2).
Photos
Multimeter: Note that this Multimeter was repaired, since there were some parts broken or missing: The On/Off-Switch cap, the stand and the battery cover have been 3d-printed, so they are not original. The battery clip was replaced due to corrosion.
