7.2 Calibration Points
Digital Pressure Gauge
9
(1) Single scale gauge: We recommend at least two pressure calibration points should be used
when calibrating the 680 gauge. Usually at 0 and 100% of full scale(Vacuum gauge should
use vacuum point).
(2)
(1) The first point should be smaller than the second point.
(2) The second point should be smaller than the third point.
Compound pressure gauge: We recommend at least a three points calibration. Usually points
will include low end vacuum point, 0 and 100% of full scale.
The calibration points can be changed to meet your requirements, only if it meets the following
conditions:
