Note:
1.
Inputs may be simulated directly at the terminal block as shown or elsewhere. If this
involves application via barriers, ensure that the barrier rating is not accidentally
exceeded.
2.
A thermocouple simulator may be substituted for the voltage calibrator.
3.
The cold junction temperature must be determined at the conditioning unit using a
separate thermometer when using a voltage calibrator.
