The weight hanger (3) should be hung on the knife edge of the load lever (4) and the
weights added and rotated to different amounts so that the slots on the weights are
offset to prevent them from accidentally being knocked off the hanger. (See photo at
right) Place the hanger on the knife edge at the end of the large lever. Sufficient space
should be maintained for adding and removing of the weights at the rear of the tester.
(See following section for hanging weights for proper load
IMPORTANT PRECAUTION: The area underneath the weights should be free from
obstruction that would prevent the weights from descending freely during the test cycle
- even possibly beyond the bottom of the tester. An obstruction could cause an incor-
rect test load or even cause the hanger to come off the load lever which could allow
the weights to fall.
If the Newage floor cabinet is used with the tester, the ridge in the back of the cabinet
is low enough that the weights will not hit as long as the operator uses a test specimen
prior to initiating a test - but a test without raising the part to the indenter could still al-
low the hanger to be dislodged.
The air regulator must be threaded into place on the side of the tester. It is shipped
with a 3/8" barb fitting for connection to factory air. It is set for 60 psi. It extends to
the right of the tester as viewed by the operator, and care should be taken so that the
regulator is not exposed to damage during operation. The minimum air requirements
are 60 psi with .4 CFM.
The electrical power is normally 110V and 60Hz (except on units that have been adapt-
ed for other power supply requirements) The amperage requirement is very low - mil-
livolts for the electronics.
The indenter and an anvil must be installed - see following section
