The Care and Use of Height Gauges

British Standard Reference : BS1643 : 2008

Select the height gauge that best fits your requirement. Ensure that the type, measuring range,ย graduation and other specifications of the height gauge are appropriate for your application.

Do not apply excessive force to the sliding and locking mechanisms of the height gauge. Should youย be unfortunate and drop the height gauge, before reusing have the height gauge recalibration/repaired by an appropriate repair agent.

When using a scriber in conjunction with a height gauge, ensure that the scriber tip is not damaged.

Thoroughly clean the height gauge after use with a lint free paper or cloth ensuring the base and theย scriber are cleaned.

Check the slider movement for smoothness, there should be no free play or intermittent restrictionย of movement. Report all non conformances to an appropriate authority.

Thoroughly clean the surface plate or surface table prior to placing the height gauge upon it, theย height gauge and datum surface should be stabilised before use.

Adjust the zero line to the datum surface before use.

Avoid parallax errors by reading the scales directly from the front and square on.

During fine adjustment to a reference standard, ensure that the base remains stable on theย measuring media, least this causes damage to either the reference standard or the height gauge.

When storing height gauges for long periods of time, or when they need oiling, use a lint freeย paper or cloth dampened with a rust preventative oil and lightly wipe each section, ensure that theย oil is spread evenly over the surfaces.

Never leave or store the height gauge for long periods of time in a high humidity environment.

Never use a height gauge that has not been calibrated, if in doubt consult an appropriate authority.

Vernier Height Gauges

BS1643 : 2008

This standard covers vernier height gauges which include a scriber for marking heights. Metric heightย gauges measure heights up to a maximum of 1000mm using a main scale and vernier scale graduatedย to read to 0.02mm. Imperial height gauges measure heights up to a maximum of 48โ€ using a mainย scale and vernier scale graduated to read to 0.001โ€. It may be uneconomical for any company or institution to invest in equipment to the level required in order to calibrate vernier height gauges fullyย in accordance with the standard.

It is highly recommended that an appropriate authority such as a UKAS approved laboratory carriesย out a full calibration on vernier height gauges at least once a year. In between UKAS calibrations at aย frequency based on usage, vernier height gauges should be calibrated in-house. A typical in-houseย calibration would include a written procedure and an associated calibration record sheet, which wouldย contain as a minimum, the following listed information:

  • Serial number
  • Location
  • Procedure number
  • Flatness of base
  • Flatness of measuring jaw
  • Parallelism of measuring jaw to datum surface
  • Flatness of measuring faces of the scriber
  • Parallelism of measuring faces of the scriber
  • Accuracy of readings
  • Results
  • Measurement uncertainty
  • Sentence if appropriate
  • Date and calibrators signature
  • 12 Traceability to National Standards

It is necessary that any person carrying out such calibration work should have received appropriateย training and have shown the ability to be confident via a suitable training authority. Training recordsย should be held and maintained.
