TESCO recommends recalibrating your Hot Socket Gap Indicator every five years. You can perform the calibration yourself with our new Hot Socket Gap Indicator Calibration Fixture.

Easy to use and traceable, TESCO’s Hot Socket Gap Indicator Calibration Fixture (Catalog No. 302) can verify the calibration of your HSGI in three easy steps!

• Step 1: Turn on the force gauge and press ZERO to zero the device.
• Step 2: Place your TESCO HSGI into the slot and manually push the lever down until the force gauge stops against the HSGI.
• Step 3: Verify the measurement is between 7 and 9 PSI.

If it measures between 7 and 9 PSI, your HSGI has passed and you may place the provided calibration label on your HSGI.

If it is outside the range, TESCO can repair the unit by either replacing the spring or calibrating the unit back to the proper operating limits.

Or … Let TESCO Calibrate For You

You may also opt to have TESCO verify the calibration of your HSGI for you. Simply schedule a calibration with your TESCO representative and ship your HSGI unit(s) to TESCO. TESCO will place a sticker of verification for each unit that passes and ships back to you.

If your HSGI is not within the proper operating limits, TESCO will repair the unit by either replacing the spring or calibrating the unit back to the proper operating limits.
