Installation
Level the instrument carefully by means of the leveling screws on the base, sighting
the spirit level from above to obtain accurate alignment. After the instrument has been
leveled, avoid shifting its location. Otherwise it will be necessary to repeat the leveling
process.
Insert penetrating needle or cone into the chuck and tighten the chuck screw.
Set the zero reference. Grasp the gear rack knob and pull up to release the clutch trigger.
With the trigger released, raise the test plunger as high as possible. If the dial reading
is not exactly zero, adjust the reading to zero by means of the zero setting screw (which
is on the bottom of the dial housing) which is adjustable as required. Use a #8 Allen
Wrench.
