 1. INSTRUMENT DESCRIPTION

**** 1.1 ORIGIN
Bought on March 2024 from ECE funds for M1022

**** 1.2 CAPABILITIES

The M302 is a Data Acquisition Mainframe with 5 slots that can host DMM, MUX, digital IO, and matrix modules.
With the right modules it is possible to reach 320 channels.
The DMM measures voltage, current, resistance, frequency, test diodes, temperature, and can scan up to 256 channels.

MC3065 6.5 DMM module:
