2. MC3132 and M3TB32
MC3132 is a 32-channel multiplexer. All the 32 channels switch both HI and LO inputs, thus providing
fully isolated signals for the DMM module. MC3132 is divided into two banks (called A and B) with 16
two-wire channels for each bank. When making 4-wire resistance measurement, the instrument
automatically pairs the channels of A bank and B bank. All the channels added into the scan list are
break-before-make. You can close multiple channels on this module when you have not configured
any channel to be part of the scan list.
MC3132 can be connected with MC3065 (the DMM module, if MC3065 is currently inserted).
MC3132 is as shown in the figure below.

M3TB32 is an external terminal block applicable to MC3132. Its appearance and detailed layout are
as shown in the figure below. There are 32 pairs of connecting terminals from the lower-left corner
to the upper-right corner corresponding to the 32 channels of MC3132 respectively. The connecting
terminals can be recognized via the labels (CH01 to CH32) below or above them.
