6.2.5 Simulating a resistance and a resistance thermometer
As already described in chapter 6.2.4 "Resistance and temperature measurement with
a resistance thermometer" the model CEP3000 can be used as a resistance simulator
for resistance and resistance thermometers or as a measuring instrument. For maximum
accuracy, the device to be checked requires in many cases a 3-wire or 4-wire measure-
ment. For information on connections, see figure 7.
