Test Block
1. Turn the power off.
2. Lower the cup stand and turn the torque arm clamp up and away.
3. Swing the torque arm back to allow removal of the test block.
4. Remove and thoroughly rinse the test block with deionized water.
5. Remove the cup and discard the test uid.
6. Remove the retaining nut and test ring.
7. Use acetone, deionized water, and a brush to clean the entire test area,
including the test ring, test block, and block holder. To prevent rust,
ensure that the entire unit is clean and dry. If the machine is to be stored
for a long period of time, coat all components with oil.
The EP Lubricity Tester is intended to remain stationary on a laboratory
bench. If it must be transported, the torque arm should be removed from the
unit, and not simply tightened down. If it is being shipped, it must be encased
inside a wooden crate with the unit bolted to the bottom of the crate. This
machine is heavy (56 pounds) and if dropped the frame may warp, which
may result in a total replacement of the unit.
After reaching the desired rpm, recheck the test block to make sure it is still
inside the holder. Sometimes the vibration of the machine will cause the block
to fall out of the Test Block Holder (#111-00-38), ending up in the bottom of
the cup. If the technician does not notice the block is out of the holder and the
torque arm is depressed the test block holder may become damaged.
