Calibration

WHY DO I NEED TO CALIBRATE MY SCALES?

Calibration is the process of testing the scale, to ensure the level of accuracy you require.

This is done in a laboratory setting, where results are dependent upon exact weights, Scale Calibration is of particular importance.

An inaccurate scale could significantly hurt your business.

In processing and manufacturing, incorrect measurements could result in product quality issues, scrapped batches, or even a product recall.

HOW OFTEN DO YOU NEED TO CALIBRATE?

How often you calibrate your scales depends on a few different factors — manufacturer’s recommendations, how often you use the scales, the environment they’re in, and how essential an exact weight is to your business.

Some are calibrated once per month, others are only calibrated once per year, while some are even checked daily for accuracy.

Old weighing systems included dials and springs, pivots, counterbalances, or levers, which required constant maintenance.

Today’s weighing systems are a little different.  They consist of an electronic instrument and strain gauge–based transducers or load cells that move only a fraction of a millimeter with weight applied, should not require constant recalibration.

SCALE ERRORS

Random scale errors can occur when:

a) the piping is not working 100% or when a bag, ladder, or pallet leans against the scale.

b) When dirt, material, debris or dust has built up beneath the platform scale

c) load cells when pressure has changed in other than a horizontal hose from the dead to the live side of the scale

d) when an electrical connection is faulty

e) when moisture is present in the junction box

f) when flexures are broken or bent

g) when low-cost or poorly designed weighing components are used
