1.1 SERVICE FACILITIES
The service area should be a stable environment.
The bench area should be clean and should contain an antistatic mat with a personnel grounding clip to
protect internal circuit boards. The ideal electrical power source for the scales should be a dedicated line
to avoid sudden fluctuations or voltage drops caused by external equipment drawing heavy current.
The service area for the scales should be away from direct sunlight, overhead heating or air conditioning
ducts, magnetic fields such as motors or large transformers or near vibrating sources such as machinery,
motors or vibrating equipment.
The power outlet should be grounded for safety. Sufficient space should be provided around the scale as
not to be affected by other equipment. This will ensure that the scale is operated under ideal conditions.
