Table 3 Time/Motion Measurements
Within ±3 %; or when the measured value is less
than 40mm, the error is less than 1.5mm.
When the correction angle is ≤60º, the PW
velocity ≤±10%.
Within the selected field range, the measurement accuracy is ensured within the
range mentioned above. The accuracy specifications are performance in the worst
conditions, or based on the real test for the system, regardless of acoustic speed
error.
