PSØ21 - Digital Amplifier for Strain GagesPrecision of a Single Measurement
The precision of a single measurement (AVRate = 1) depends on 2 parameters:
As long as the update rate is not higher than 5 kHz we recommend working with measurement range 2. Setting the discharge time to 50 -100 µs, PSØ21 has the performance shown in the table on the right.
Internal Averaging
PSØ21 internally improves the precision of the measurement results by averaging. The measuring principle guarantees that no significant systematic errors affect the result. The standard deviation is improved by the square root of the averaging rate.
