Scale Micrometer, o.e_
2. This device was evaluated by a number of IAD ajnalysts,
representative of all IAD branches, and the following comments are submitted
for your consideration:
a. The reticule is very clear and the addition of the counter
aids greatly in reading distances. The readings being made directly
in feet is a desirable feature.
This memorandum is in confirmation of the verbal comments made
SS/IAD, to of your staff, regarding the
rojec e Scale Microme er, o el II.
b. The lamp housing which provides illumination for the reticule
tends to become excessively hot during sustained use.
c. A slight slippage was noticed in the drum dividing each
rotation into 100 parts.
d. Too much margin for error in ascertaining the; proper alignment
of the plane of the reticule with that of the phottograph.
e. The micrometer screw drive knob is very stiffi--precluding
very fine measurements.
f. The half inch movement limitation and the awkward procedure
necessary to cause the present bisecting line to travel from one
object to another could be improved.
g. The instruction booklet accompanying the geariis very poorly
written, and would be improved by the addition ofia keyed photograph
or line drawing of the instrument illustrating eabh of the operational
parts.

receiving the use we had anticipated. Although in general the Model II
shows improvement over the Model I, the IAD requirement, for this type
mensuration equipment is not sufficient to justify further developments
or procurement at this time.
ii. As always, the IAD appreciates the opportunit of evaluating
developmental items submitted to it by the Plans & Development Staff, and
As you are aware, the IAD presently has several of the
rojected Scale Micrometers, Model I. These unit are not presently
the efforts of the P&DS on IAD's behalf.
