Wiring Terminals • The voltage output (control output) is not electrically insulated from the internal circuits. When using a grounded thermocouple, do not connect the control output terminals to the ground. If the control output terminals are connected to the ground, errors will occur in the measured temper- ature values as a result of leakage current.
