General information and warnings
1.2.3 Precautions
Here are some things which may cause inaccuracy in your scale operation:
l
Change in temperature. If the temperature changes more than a few
degrees, you must recalibrate the scale. Allow the scale to warm up for 20-30
minutes prior to use.
l
Changes in scale location or an unlevel work surface.
l
Uncentered weights on the scale platen.
l
Jarring of the scale during operation.
l
Weight accuracy is critical. Keep weights clean and carefully stored. If
dropped or damaged, have weights inspected against known standards.
l
Static electricity can cause the scale display to drift. If static buildup is
evident, wipe the scale with an antistatic sheet or use antistatic spray. Spray
on a clean soft cloth first. Do not allow spray to get into the mechanism.
l
If powder should get inside the unit, stop operation immediately and do not
use the scale until it has been serviced.
l
Do not press on the scale platen with your hand. You can damage the
loadcell. This is a precision instrument.
1.2.4 Records
Keep complete records of reloads. Apply a descriptive label to each box showing the
date produced, the primer, powder and bullet used. Never attempt to guess at the
identity of your ammunition.
