Element order changed recommendations

To eliminate the errors caused by lead wire resistance changes, it is recommended to use transmitters that accept 4-wire RTD inputs as a standard feature. In order to eliminate errors by self-heating, the measuring current should be minimized. For platinum elements, it should not exceed 250 pA. The best installation practice is to place all electronics directly on top of the thermowell and thereby eliminate lead wire and noise effects. If this cannot be done, the lead wires should be twisted and shielded the wires should also not be stressed, strained, or made to go through steep gradients. The... 

The Secondary Education Commission (1953) also recommended a reform in system of examinations. In this report we find, "In order to reduce the element of subjectivity of essay-type tests, objective tests of attainment should be widely introduced side by side. Moreover the nature of the tests and type of questions should be thoroughly changed. They should be such as to discourage cramming and encourage intelligent understanding".
