Each thermocouple input must have either a cold junction assembly (part number CM30/0052) or
shorting link (part number RVG200/0118) fitted. Each analog input card with a thermocouple input must
have a minimum of 1 cold junction assembly fitted. For applications requiring maximum thermocouple
accuracy, it is recommended that each thermocouple input is fitted with a cold junction assembly.
