3-10 Basic DMM Operation Model 2750 Multimeter/Switch System User’s Manual
Model 7700 switching module
Connections for the Model 7700 switching module are shown in Figure 3-3. For basic
DCV and ACV measurements (Figure 3-3A and B), channels 1 through 20 can be used.
Ratio and channel average calculations — Ratio calculates the reading ratio of two
channels, while channel average calculates the reading average of two channels. For these
calculations, paired switching channels are used. Primary channels 1 through 10 are paired
to channels 11 through 20 (channel 1 paired to channel 11, channel 2 paired to channel 12,
and so on). As shown in Figure 3-3C, one DC voltage source is connected to a primary
channel (i.e., 104), and the other source is connected to its paired channel (i.e., 114).
NOTE The ratio and channel average calculations are covered in Section 5.
