This performance procedure is intended for:

  • checking the instrument's specification.
  • incoming inspection to determine the ac­ceptability of newly purchased instruments and recently recalibrated instruments.
  • checking the necessity of recalibration af­ter the specified recalibration intervals.

It is not necessary to remove the instrument cover to perform this procedure.
