5 To connect the signals to be measured into the external DMM
Use the External Port for Analog Bus Interface (optional) to connect the analog
bus interface at the rear panel of M300 and the measurement signal input
terminal of the external DMM.
If only one multiplexer module is used, you can connect the corresponding
terminals (as shown in the figure below) on the external terminal block to the
measurement signal input terminal of the external DMM.
