Snap Gauge | Adds to 990-PG1 Training System for Hands-On Learning

Model Name: Snap Gauge

Model Number: 99-PG2

Learning Topics

Amatrol’s Snap Gauge training (99-PG2) is a highly-precise gauge used throughout many types of industries. The 99-PG2 includes a digital snap gauge and a master part turned to precisely 0.500”. Adding it to the Portable Precision Gauging Learning System (990-PG1), the Snap Gauge training gives learners expanded knowledge of advanced industrial measuring devices. It also fits securely into the 990-PG1’s portable case and integrates seamlessly into the training.

A snap gauge uses adjustable anvils to precisely measure a cylindrical part’s diameter against a master part to which it is calibrated. Using the 990-PG1’s interactive multimedia curriculum, learners will become familiar with the components, function, and operation of a snap gauge, as well as how to take precise measurements and assess positive and negative variance to determine whether parts are within acceptable tolerance levels.

How Do You Use a Snap Gauge?

Proper operation of a snap gauge is essential to ensure accurate measurements. Assuming it has already been mastered, there are five steps to perform a measurement using a snap gauge:

  1. Grasp the Gauge by the Insulated Handle – It is important to remember to hold the gauge by the insulated handle since it is designed to reduce the heat transfer from the hand to the instrument.
  2. Place the Part Against the Fixed Anvil –  Since the fixed anvil provides the reference surface, the part should first be placed against this anvil. By doing this, you assure more accurate and consistent measurements.
  3. Pivot the Gauge Forward – To properly engage the part in the gauge, pivot the gauge forward while continuing to hold the part against the fixed anvil. When the pressure on the upper anvil (due to the spring tension) is overcome, the part will snap into place against the backstop.
  4. Make Sure the Part is Square Against the Backstop – In order to get accurate readings, the part must be held squarely against the anvils and the backstop. If the part is square against the backstop, the part is properly oriented.
  5. Obtain a Measurement Reading from the Indicator – Once the part is properly oriented, you can take a reading by observing the display of the indicator. Most of the time, the indicator will display the value of the variance between the tested part and the master. You can use the reading to determine if the part feature is within the desired tolerance.
