Table 5-2 Equipment Needed for Calibration

• A compensated calibrator with ± 0.02 % accuracy.
• Thermocouple extension wire that corresponds with the type of
thermocouple that will be used with the recorder input.
• 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 recorder input.
• Two insulated copper leads for connecting the thermocouple
extension wire from the ice baths to the precision calibrator.
• Two containers of crushed ice, or an ice point reference.
• A resistance decade box, with ± 0.02 % accuracy, capable of
providing stepped resistance values over a minimum range of 0 ohms
to 1400 ohms with a resolution of 0.01 ohm.
• Three insulated copper leads for connecting the decade box to the
recorder.
• A calibrating device with ± 0.02 % accuracy for use as a signal
source.
• Two insulated copper leads for connecting the calibrator to the
recorder.
