  • Visible / exposed wires and correct connection to plug
  • Signs of overheating / trapped cables

Equipment Inspection

  • Physical inspection of equipment eg level, draftshield
  • Keypad functionality check: tare, on /off, print function and output
  • Display functionality check: display segments / equipment stability check
  • Check for interference with the pan


  • Remove pan and check for debris
  • Clean pan and spill guard
  • External surfaces and casings of the equipment

Balances and scales are not perfect measuring instruments. It is possible (for a number of different reasons) that they could stop weighing accurately. When this occurs an adjustment must be performed to correct the error. How these adjustments are performed varies considerably from manufacturer to manufacturer and even range to range. European Instruments Ltd has the technical knowledge and equipment required to perform the following adjustments as required:

  • Span
  • Linearity
  • Eccentricity
  • Internal calibration overwrite
