Equipment Needed
Thermocouple
Inputs (Ice Bath)
Inputs (Ice Bath)
• A calibrating device with at least ± 0.02 % accuracy for use as a
signal source such as a millivolt source.
• Thermocouple extension wire that corresponds with the type of
thermocouple that will be used with the controller input.
• Two insulated copper leads for connecting the thermocouple
extension wire from the ice baths to the mV source.
• Two containers of crushed ice.
