Why Calibrate a GMT-232?

A DMC GMT-232 instrument is designed to terminate wire splices. It is important that a DMC GMT-232 is constantly working properly. But what happens when this tool becomes unreliable? It is critical that the DMC GMT-232 is calibrated periodically to meet industry standards.

If your GMT-232 isn’t properly calibrated you’re going to lose function in three major areas.

  1.  Ratchet adjustment
    A calibrated GMT-232 applies a compression force of a minimum of 40 pounds, 1.25 inches from the end of the handles. Without calibration, the GMT-232 will not apply this type of pressure, causing the jaws not to close before the the ratchet releases the handles.
  2. Jaw closing
    If the jaws are not fully closing, a “go” gage will not fit in the space between the indenter and its corresponding cavity. The gage must freely pass between the jaw halves, and this just isn’t possible if the GMT-232 isn’t calibrated.
  3. Secure ratchet
    A properly calibrated ratchet is secured to prevent unauthorized adjustment. Without calibration this function will not perform properly on the GMT-232.

A good way to help keep calibration times to the minimum is by inspecting your GMT-232 daily. You should be cleaning all the dust and dirt off the instrument and storing the tool with the handles closed. No matter how well you take care of your GMT-232 though, daily use will unalign the instrument and it will need to be recalibrated.

Overall, periodically calibrating your DMC GMT-232 is the best choice when working within a standard. e2b calibration is an ISO/IEC 17025 accredited calibration and repair laboratory providing a full scope of services (traceable to NIST) for most popular calibration, test, and measurement instruments.
