Cautions.
1. Calibrate the scale with wearing weights when first used, changes in latitude and longitude will affect its accuracy.
2. The scale must be placed on a very stable level platform, even small vibrations can affect the readings, sometimes significantly.
3. Do not load the scale with more than the maximum capacity weight.
4. Avoid shaking, dropping or otherwise jolting the balance. This is a precision instrument and must be handled with extreme care.
