WebFrom Table 3.1, the percent of FSR calculated for accuracy is 2 or 4%, depending on whether the calibration fluid is greater or less than 50% of FSR. If our calibration fluid is 4 Poise, we would calculate accuracy as 2% of FSR, or 2% of 8.333. Instrument accuracy would thus be .1666, rounded to .17 Poise.
