used. If time and circumstances permit, expend a
detonator to determine arming time. Conduct test as
close to operational conditions as possible.
2. Assemble kit as instructed in ( b ) 1
through 7 below.
3. Leave base plug (shipping plug) in
place.
4. Install delay pellet to be tested. Replace
protective cover.
5. Submerge and secure detonator in
desired position.
6. Remove carboard protective cover and
safety pin. Start timing.
7. After half the suggested delay time has
elapsed, apply pressure to diaphragm, using eraser
end of pencil to determine if firing pin will snap.
Repeat this procedure every 30 seconds.
8. The arming time determined above is
only approximate even if test was done in exact
position that operational detonator will occupy.
