We use a calibrated Chattilon Digital Force Gauge and an Easton Digital Grain Scale
Using both experiments and grain scale
modelling, the SEISMIC project will in turn directly test boundary element models for large scale fault slip.
Section 1 on measurement contains sub-sections on local scale measurements, diffraction at grain scale
and multistate diffraction, diffraction gradients and instrumental developments, mechanical relaxation methods, and acoustics and electromagnetics methods.
In some cases the weight can double and only a grain scale
could tell the difference.
One handy little grain scale
designed for reloading ammunition but also well suited to archery is the Mini-Digital Reloading Scale from MTM Case-Gard ($40).
Weight: Vane-unit weight was measured using an Easton Digital Grain Scale
, calibrated according to manufacturer specifications.
Then, using an electronic grain scale
and a spine tester, I measure and record the weight, straightness, and static spine of each.
Some shooters even weigh charges on a grain scale
(as opposed to volumetric measuring)--I once went to the trouble myself, but subsequent conversations with competition shooters convinced me the practice was unnecessary.
Visually you won't notice much difference, but you'll notice a difference on the grain scale
This happened because I didn't have a grain scale
, and once you epoxy the inserts, you are stuck with the weight.
Mathews also brought a shooting machine, a chronograph, and an electronic grain scale
to the ATA show.
Today his collection includes egg scales, grain scales
