5.3 Input Calibration Preliminary Information

Equipment needed

Table 5-2lists 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.

Table 5-2 Equipment Needed for Calibration

Type of Input		Equipment Needed
Thermocouple Inputs	•	A compensated calibrator with ± 0.02 % accuracy.
(Compensated Calibrator)	•	Thermocouple extension wire that corresponds with the type of
		thermocouple that will be used with the recorder input.
Thermocouple Inputs	•	A calibrating device with ± 0.02 % accuracy for use as a signal source
(Ice Bath)		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.
RTD (Resistance Temperature	•	A resistance decade box, with ± 0.02 % accuracy, capable of
Detector)		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.
Milliamp, Millivolt, and Volts	•	A calibrating device with ± 0.02 % accuracy for use as a signal source.
Inputs	• Two insulated copper leads for connecting the calibrator to the
		recorder.
