Calibration Frequently Asked Questions
The calibration of all models is password-protected. This helps prevent unauthorized access to the calibration mode or any accidental changes. The calibration password and manuals can be downloaded from this website. The questions frequently asked about calibration are listed below to help guide you with the most common issues.

How often do I need to calibrate my force gauge or torque tester?
Although the included Nextech calibration certification is valid for one year, under normal use it is recommended that you calibrate the gauge at least every 2 years. However, some organizations have required quality standards that govern the level of calibration assurance as well as the period between calibrations. This is usually an annual process.
Important note: If, within the diagnostics menu page, an increased Current Offset is observed compared to the “original offset”, normally between 2-5% variance. Or if the force gauge has sustained an Overload while powered on or off, the gauge should be considered to be out of tolerance and should be inspected before re-use.
What is the password to re-calibrate the gauge?

I need a NIST Traceable calibration certificate from a certified lab, can I send the gauge to Nextech Sales service to do it?
Although we use NIST-traceable equipment in our calibration process, our service center is not a NIST-certified calibration lab. Therefore, we suggest that you send the gauge directly to the certified calibration lab of your choice. This will reduce your shipping costs and the total time involved.
The shipping costs involved in sending in a gauge for calibration are very high. Is there any lower-cost option?
The need for calibration highly depends on the required levels of accuracy, reliability, documentation, and analytical importance of test results. For example, a hobbyist will likely have different needs in these areas than an organization involved in aerospace manufacturing.
If there is no real need, you can delay the calibration. Nextech Sales occasionally offers a rebate program to exchange your old gauge with a new one. It will often cost about the same, or in some cases less than sending the gauge in for calibration, and you get a new, calibrated unit with a full one-year warranty.
Where can I send the gauge for calibration?
Some organizations are required to have a certificate of calibration, with accepted traceable standards, that are recognized within their country. For these cases, you will need to send the gauge to a nationally certified lab that can perform this process. Suitable labs can be found by searching the internet.
What should I do if my gauge/tester fails calibration?
Calibrating a gauge can be costly. If the device has been properly cared for and is in good working order, it can be easily recalibrated to meet our manufacturer’s specifications. However, your gauge should be repaired or replaced to avoid the additional expense of a failed calibration if it has sustained damage, has been overloaded, or if the offset variance exceeds 2-5%.
To avoid any possible “hidden costs” at third-party labs, we strongly suggest that you speak with your calibration lab in advance about this process. Request an itemized price quote for all chargeable services.
Example:
- Is the quoted price “all-inclusive”, and what is the cost if they cannot complete the calibration?
- If the gauge is “out of tolerance”, is there an extra charge for adjusting the gauge’s calibration?
It is also recommended to replace the battery before the calibration process, so you may want to consider this in advance.
