1. Place the load frame on a lab bench or other suitable mounting
location and inset the load holding screw into the block at the
channel end from the bottom, so that the ball end of the screw will
make contact with the bottom of the lever arm when changing to the
next higher load. Attach the weight hanger with the pin provided.
There are three (3) ratio positions for this hanger (9:1, 10:1 and 11:1).
The chart that follows on the next page is set up for the 10:1 ratio
with a 2.5” diameter sample. Be sure you have sufficient clearance
for the weight hanger with weights before securing the base to the
tabletop using the (2) anchor bolts supplied.
2. Attach the dial indicator support rod to the right of the base. Next,
attach the dial indicator holder to the support rod. Finally, attach the
dial indicator to the holder.
3. Screw the counter weight threaded rod into the rear of the lever arm,
about 1” and tighten the jam nut. Adjust the counter-weight until the
lever balances at a level position with the top loading arm vertical
and tighten the nut. You might want to consider adjusting the weight
until there is a seating load on the sample (ASTM D2435 for details)
