2.1 General Description
Allvis Electronic Measuring System
A lightweight telescoping electronic measuring arm made up of
aluminum and composite materials forms the main component
of the system.
A quick release socket built into the rear end of the telescoping
arm accepts any one of six snap-in height calibration rods – rod
numbers A to F.
A socket located on the inside of the self-centering magnet
allows it to be snapped onto the ball of any one of the height
calibration rods.
The housing of the electronic control unit with digital display
located on the front end of the arm incorporates an easy to
operate twist-lock socket for each of the 4 different lengths of
datum height rods.
An adjustable rotating datum height level assembly is built into
the top of the housing of the electronic control unit. Level
adjustment is by thumb wheel.
Measurement control buttons are located on the front face of
the electronic control unit and a battery compartment for the
two AA batteries is built in to the lower part of the housing.
Distance measurements from center of the rear calibrated rod
holder to center of the front datum height rod holder is
generated by electronic impulses produced by a rotating wheel
inside the arm.
