Performing Periodic inspections
It is recommended that repeatability inspections, corner load error inspections and instrumental error
inspections (performance inspections) are carried out periodically. Although these inspections may be
carried out independently, they can also be carried out in series, as explained below.
Precautions
• These performance inspections may be considered to be a yardstick for determining if the balance is operating normally.
• Carry out the performance inspections in a location free from sudden changes in room temperature.
• Place the weights inside the weighing chamber in advance to make sure the inspections are carried out without any
differences in temperature between the weighing chamber and the weights.
• Use elongated pincers to place and remove the weights, and do not put hands inside the weighing chamber.
