6 Safety Manual
55
With proof test B, the following values for the proof test coverage (PTC) can be achieved:
15 Switch off test piece and connect current meter using a burden of 500 Ω between
connections 42(+) and 41(-).
Switch on test piece and configure analog output for simulation of current output
signal 21.2 mA.
The output signal recorded using the current meter must be 21.18 mA to
21.22 mA.
Configure analog output for simulation of current output signal 3.6 mA. The output
signal recorded using the current meter must be 3.59 mA to 3.61 mA.
Verification that the output driv-
er stage of the analog output
can drive the maximum permis-
sible burden.
