Round Telescopic Insulation Height Measuring Rod - Photo ID 84880 

Round telescopic insulating height measuring rod is calibrated to metric
scale. The main insulating rod is made of high strength epoxy glass fiber
tube. The product has excellent electrical and mechanical properties.
The height measuring rod is light in weight and easy to operate, it can
measure the height of overhead power line and communication line from
the ground. The calibration of the product surface is clear and accurate,
and the measuring error is not less than 5cm.
How to use it:
1.When the height measuring rod is used, the rod cap is opened, and the
hook is tightened on the screw of the details, and then gradually pulled out to the two sections of the Chimera, with a little force, and the edge of the twist is pulled out to ensure that the vertical lines of the two sections
of the scale are aligned, until the semicircle marks between the two sections form a circle, then verify that the snap is fully ejected to ensure
a complete lock between the two sections.
2.After the use of the height of the bar after the draw, one hand holding the lower thick pipe, with the thumb to hold the snap button, the other
hand holding the top of a thin section, twist the edge up push, take back
section by section.
3.The hook of the height measuring rod is screwed down, and can be
installed with an electric apparatus head, and can be used as an electric
apparatus rod.
Scale reading method:
After hook the altimeter pole to the measured object, make sure the
altimeter pole is perpendicular to the ground, then observe the figures of
the hand-held altimeter pole, the upper end of the node is aligned with the scale line, this number is the height of the object being measured.
