5 Connect resistance decade for simulation of the input signal that is appropriate for
the chosen configuration. Verify whether the expected value (display value) corre-
sponds to the input signal.
Test the current device status of the test piece using the setup program.
Status must be 'OK'.
If, for example, Pt100 is configured, 0 °C must be displayed at the input at 100 Ω.
Verification that there is no error
status internally if display cor-
rect without error signaling.
6 Produce line break for each of the 4 lines. The test piece must signal an error (dis-
play and LED).
Verification of proper function of
the probe break/line break de-
tection.
7 Switch off test piece and replace short-circuit jumper at the analog output with the
current meter; connection 41(+) and connection 42(-).
Switch on test piece again.
Check output signal by applying a corresponding reference signal using a resis-
tance decade at two points; for the start of measurement (measuring range start
up to +20 % of the range) and for the end of measurement (measuring range end
up to -20 % of the range).
The analog output signal corresponding to the reference signal must be within the
safety measurement deviation.
Furthermore, the display value must correspond to the reference signal according
to the configuration.
Verification that the measuring
chain for RTD is within the safe-
ty measurement deviation.
