Table 5-2 Equipment Needed

•
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.
•
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 controller input.
•
A decade box, with at least ± 0.02 % accuracy, capable of providing
stepped resistance values over a minimum range of 0 to 1650 ohms
with a resolution of 0.001 ohm.
•
Three insulated copper leads of equal length for connecting the
decade box to the controller.
•
A calibrating device with at least ± 0.02 % accuracy for use as a
signal source.
•
Two insulated copper leads for connecting the calibrator to the
controller.
•
Place current source at zero before switching ON.
•
Do not switch current sources OFF/ON while connected to the
UDC3200 input.
