Accuracy

The gauge is capable of measuring pressures to the accuracy indicated below. See the calibration report for the actual accuracy of this gauge. The claim for accuracy is valid only when the gauge is operated according to the instructions provided with the equipment. In addition, the claim is valid when the value of gravity acting upon the weights is known to +/-0.001 cm sec2.

Accuracy is defined as the departure of the measured pressure from the true pressure. The value is based on a simple error analysis of the calibration experiment and represents the sum of the systematic errors and two standard deviations of the random variability of the measurement process.

Gauge Pressure (0.0035% Class)

High Range Piston	0.0035 percent of reading
(0.013 sq in area)	or 0.002 psi, whichever is greater
Mid Range Piston	0.0035 percent of reading
(0.13 sq in area)	or 0.0002 psi, whichever is greater
Low Range Piston	0.0035 percent of reading
(0.52 sq in area)	or 0.00005 psi, whichever is greater
