Model 791 Calibration Plate
(for Tiltmeters and Inclinometers)
The portable Model 791 Calibration
Plate is used to verify calibration of any
gravity- referenced tiltmeter or
inclinometer. NIST-
traceable gage blocks are placed under
one end of the plate to rotate the
tiltmeter through a series of known
angles.
PORTABLE CALIBRATION PLATE
FOR TILTMETERS AND
INCLINOMETERS
The output of the tiltmeter at each angle
is recorded and then compared to the
angles established by the gage blocks.
Data from the calibration procedure also
can be used to determine the tiltmeter’s
linear “best fit” scale factor and
polynomial calibration curve. The
Calibration Plate contains threaded holes
for attaching most Jewell Instruments
tiltmeters, tilt sensors, and clinometers.
