Equipment needed 

Table 5-2 lists the equipment required to calibrate various types of inputs. You will also need a medium size 
bladed screwdriver for general use and a small bladed screwdriver for use with the screws on the connector 
plugs. 

 

•  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.
