FIGURE 3.1-7. The parallelogram is stabilized with one hand while
the dashpot rod is unscrewed with the other.
10. Clean the inside of the instrument.
11. Inspect all flexures (leaf springs). There are two pair—one horizontal and
one vertical at each fulcrum of the parallelogram (see Figure 3.1-2).
12. Replace the ones that are damaged (broken, bent, kinked or cracked).
13. Check if all screws holding the flexures are tight. The measurement
accuracy, resolution, and stability of the instrument depend on the
parallelogram mechanism being properly secured.
3.2 Internal Enclosure and Load Cell
1. Unpack the enclosure, but leave the load cell taped to the top until the
enclosure is firmly attached to the base.
2. Re-install the two bolts that held the punch mechanism, but remove all
washers. Do not tighten the two bolts at this point; leave a gap of
approximately 1/8” under the bolt head to allow clearance for the
enclosure bracket to slide freely under the bolt head (Figure 3.2-1).
