Model 196 DMM connections
Connect the Model 196 or other similar DMM to the matrix
card using the general configuration shown in Figure 2-7.
The VOLTS OHMS HI and LO terminals should be connect-
ed to the desired rows using triax/banana cables. For 4-wire
ohms measurements, the OHMS SENSE HI and LO termi-
nals should be connected to two additional rows using the
same type of cables.
NOTE
For low-level voltage measurements, con-
nect the inner shield of the HI cable to
VOLT OHMS LO to minimize noise.
196 DMM
Connect inner shield to LO for
low-level measurements.
(Modify the cable of Figure 2-4.)
