How to Calibrate Gauge Blocks

Gauge blocks are used every day in manufacturing to aid in the setup of machines, check product quality and calibrate measurement tools. They are simple to use and provide precise measurements between two objects. To function correctly, calibrate them periodically.

Gauge blocks can be calibrated using calipers
  1. Clean the gauge block using a chamois or soft cloth. Use mineral spirits if the block is really dirty.

  2. Measure the gauge block using a calibrated caliper. Verify that the reading on the caliper matches the specified dimension on the gauge block. If it does not, the gauge block is out of calibration and needs to be replaced.

  3. Measure the gauge block at different locations using the calipers. Ensure that all measurements on the caliper match the specified dimension. If any measurement is incorrect, the gauge block is out of calibration and needs to be replaced.

  4. Record the date of calibration, and determine the next date to calibrate the blocks. A typical cycle is every six months or every year

  5. Tip

    Calibrate your gauge blocks to traceable N.I.S.T standards
