When sharpness is tested, force is applied to the test media by the edge of the blade. The force increases until the test media severs. When the media severs the force decreases. The BESS tester displays the amount of force applied to the media at the moment it severs. In other words, the maximum amount of force required to sever the test media.
The BESS tester is extremely accurate. Force of impact of a falling object exceeds the resting weight of the impacting object. If an object is dropped onto the pressure plate of a BESS tester, the force of impact is displayed, not the resting weight of the object. Attempting to place a weight on the tester by hand without influencing the tester is almost impossible. If the object is released above the pressure plate, even by a tiny distance, so that it falls onto the pressure plate the displayed force will vary from the resting weight of the object. If the object is pressed onto the pressure plate, the displayed weight will vary from the resting weight of the object due to the influence of your hand.
Attempting to place a weight on the tester by hand without influencing the tester is almost impossible. Your observations are normal and expected. Sharpness testing is different from simply weighing an object.
Let me know if that does not make sense or if you have further questions.
