Appendix C. How To Select Scope Mounting System - ATN PS-22 Operator's Manual

HOw TO SELECT SCOPE MOUNTING SYSTEM
REqUIRED FOR YOUR DAYTIME SCOPE
By selecting the appropriate Scope mounting System (with In-
serts) you can mount the pS-22 onto a daytime scope with an
objective tube diameter from 25 to 62 mm. at the table 2-1 Scope
mounting System sizes (#1-6) and Insert sizes for different scope
examples are provided.
If your specific daytime scope is not listed in table 2-1, before
mounting procedure you have to select the proper Scope mount-
ing System (and Insert) required.
to do this, perform the following actions:
1. Determine your daytime scope objective tube diameter (ex-
ternal - not diameter of the glass lens) with a millimeter ruler
(with a trammel for more accurate results) as shown in figure
C-1.
2. Select from the table 2-1 the Insert size closest (larger) to
the value measured (Insert size is also specified at an Insert
body). Do the selection in Insert group that corresponds to the
same Scope mounting System (for example, Scope mounting
System #2).
3. the Scope mounting System you need is the one that corre-
sponds to Insert size select-
ed at the table 2-1.
For example, if your scope ob-
jective tube diameter is equal to
46 mm then you should select
Insert with size of 46,7 mm and
corresponding Scope mounting
Systems #3 from the table 2-1.
