ue leads,The remainder of the resistance in the adjust-able arm is equal to the resistance of the plati-num wire at the temperature of the measure-ment. To deduce the temperature from a resist-ance measurement it is necessary to firststandardise the thermometer by measuringits resistance at two… … 100 -lOO -0 This assumes that the change of resistance with temperature followsa linear law. When greater accuracy is required it may be obtainedby standardising at three known temperatures and assuming that 576 TECHNICAL APPLICATIONS [465 the resistance varies according to a parabolic formvila.
