Calibration procedure finished.
Calibration: FAILED.
Zero test: ok (0.0000, limit:
absolute +/-0.0001)
Signal test: fail (52.4083, limits:
recalibration +/-0.0300 rejection +/-
0.2000)
Remove calibrator assembly and type
YES: YES

Guided Calibration
Procedure failed due to
Signal Value Test failure.
Signal Value deviation is
measured to 52.4%. Limit for
rejection is ±0.2 (±20%).
Table 34 below shows an example of a Guided Calibration Procedure
where the Zero Signal Test (and therefore the Calibration Procedure)
fails due to a too high receiver signal with blocked transmitter and
receiver.
