Table 6-2 Equipment Needed

•
A calibrating device with ± 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 indicator 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 ± 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 indicator input.
•
A decade box, with ± 0.02 % accuracy, capable of providing stepped
resistance values over a minimum range of 0 to 1400 ohms with a
resolution of 0.1 ohm.
•
Three insulated copper leads of equal length for connecting the
decade box to the indicator.
•
A calibrating device with ± 0.02 % accuracy for use as a signal
source.
•
Two insulated copper leads for connecting the calibrator to the
indicator.
•
Place current source at zero before switching ON.
•
Do not switch current sources OFF/ON while connected to the
UDC2300 input.
For Radiamatic inputs only, set Emissivity value to 1.0. See Section 4.5 –
Configuration Set Up prompt INPUT1, function prompt EMISS.
