APPENDIX A
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 PS28 onto a daytime scope with an ob-
jective tube diameter from 47 to 58,7 mm. At the Table 2-1 Scope
Mounting System sizes (#1-2) 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 (exter-
nal - not diameter of the glass lens) with a metric ruler (with a tram-
mel for more accurate results) as shown in Figure B-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 ex-
ample, Scope Mounting System
#2).
3. The Scope Mounting System
you need is the one that corre-
sponds to Insert size selected at
the Table 2-1.
For example, if your scope ob-
jective tube diameter is equal to
56 mm then you should select
Insert with size of 56 mm and
corresponding Scope Mounting
0.5 mm
Systems #1 from the Table 2-1.
