2.3 Maintenance and handling
The Dillon Dynamometer is a precision instrument and will
provide many years of dependable service if given
reasonable care and suitable protection. Many firms make
it a regular practice to return Dynamometers to their
distributors at 6 to 8 month intervals (depending upon how
much they are used) to have accuracy recertified. We
recommend this at least once a year. Consult with your
Dillon distributor concerning any questions you may have
about recalibration intervals. Your area may require periodic
proof testing. Consult your local regulations.
Transport and store the dynamometer in the supplied
storage case when not in use.
2.4 Operation
Zero the dynamometer for best accuracy. To properly zero
the instrument when using the max pointer, adjust the black
needle below the desired zero point using the zero
adjustment wheel on the rear of the case. Move the red
maximum pointer counterclockwise until it contacts the
black needle. Use the zero adjustment wheel to
simultaneously move both pointers to the desired zero
point. This procedure will prevent the slight drag of the max
pointer from influencing the displayed reading. If the max
pointer is not required, rotate the red pointer clockwise until
it reaches the zero position and operate normally.
Dillon Mechanical Dynamometers permit zeroing of up to
20% of instrument capacity. Do not zero off a deadload and
then use the instrument to capacity.
WARNING: Failure to adjust the max
hand prior to use of the Dynamometer
WILL affect the readings if the max hand
is used.
