712B/714B
Calibration Manual
Required Equipment
The equipment listed in Table 2 is necessary to do the calibration and test for the
712B. The equipment listed in Table 3 is necessary to do the calibration and test
for the 714B.
Note
Fluke 5522A and Fluke 8508A need an 8-hour warmup period
before the calibration starts. The 5522A needs to zero all the
functions weekly and zero Ohms output function every day. The
8508A needs to zero the dc V measurement function, the 4-Wire
Ohms measurement function and the DCI measurement function.

Before using the mV output function of 5522A, record the 5522A output setting by the reading of the
8508A.
The absolute uncertainties of the DMM’s dc voltage need to be better than 10 ppm+0.2 μV in the range of
0 mV and 100 mV.
The accuracy (MAX) of standard sensors should be better than 0.05 °C.
The accuracy (MAX) of the TC sensor should be better than 0.05 °C.
