Starter System Setup
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
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.
