Figure 15 shows how to connect the Multi-Cal-Power cable to power supplies and to the DMM. This

connection is for current loop output sensor modules. Refer to Table 3 for an illustration of how to set the

jumpers on the Multi-Cal-Test PCA for current loop configuration.

NOTE:

It is very important that the device power supply is floating. In other words, the negative

terminal on the device power supply is not connected to GND on the

±15-V supply. Also, this

supply should not be referenced to earth ground.
