4. Wiring
Use Differential Voltage measurement instruction 2 to measure the CM3. The
CM3 wiring diagram is shown in Figure 4-1.
The red lead is connected to the high side (H) of any differential channel. The
blue lead is connected to the corresponding low (L) side of the differential
channel. On a CR10(X) or CR510, the white lead is connected to an analog
ground (AG) and the clear to ground (G). On the CR23X, 21X or CR7 both the
white and clear leads are connected to ground (
).
While a differential measurement is better and preferred, the CM3 can be
measured on a single-ended channel using Instruction 1 if the power induced
voltages discussed in the following paragraph are prevented.
