Fiber Optic Test Equipment Calibration FAQ's

Why Should I Calibrate?
Test equipment items are highly crucial to your company because they check and measure the work you produce. They measure the quality of your services, and in the end, they are responsible for the success and profitability of your business and reputation.


How Often Do I Calibrate?
Manufacturers' specifications will indicate how often to calibrate their tools, but critical measurements may require different intervals. Most equipment in the fiber optic industry generally has an annual requirement.


Is It A Requirement That I Calibrate?
Regular calibration of instruments is necessary because the accuracy of their measurements starts to drop over time. You have to make sure the instruments don't get out of calibration. You will observe that the accuracy of major components of instruments will start to shift over time. However, this shift is minor and won't affect the measurements if you maintain a good calibration schedule because calibrating your equipment will find and correct the changes.


If I Use My Test Equipment Very Little Do I Still Need To Calibrate?

The cost of calibrating a new piece of test equipment is nothing compared to the risks an inaccurate measurement can have on your operations. Even if you rarely use the item, the environment can make subtle changes to the inside components creating a change from factory specs.

 

Is It OK To Subject Equipment To Extreme Cold Or Heat?
Extreme temperatures, whether cold or hot, affect both fiber optic technicians and their test equipment. Job sites may be thermally regulated, but technicians need to remember optical test equipment should not be left in vehicles. Leaving equipment in a vehicle overnight exacerbates many issues. Test measurements are impacted by thermal changes in the test instruments themselves. Thus, bringing test instruments stored overnight in a vehicle into a testing environment of a different temperature can contribute to measurement errors. Test equipment can take an hour or more to fully adjust and stabilize to a new ambient temperature. Hot and cold weather must be considered. To improve your odds of getting accurate measurements, use setup time to your advantage. Bringing fiber optic or electronic test gear onto the job site must be a priority. Take the equipment out of the carrying cases immediately and spread test instruments out to let them begin adjusting to the new temperature and continue with the job setup.



I Dropped My Equipment, Should I Have It Calibrated?
If your instrument took a tumble, such as a solid physical impact it is highly recommended that you send that item out for calibration. With such an impact it is likely something internal has shifted or moved out of spec.



Why Should I Use FIS?
Our FIS American Standards Lab is certified and audited annually under ISO 9001-2008/2015 quality standards. Our calibrations are regulated to NIST traceable standards. Under these standards, our calibrations meet or exceed US calibration requirements for verification calibrations.  All calibrations include a NIST calibration/verification certificate and test reports including as received and as returned results. FIS has some of the best lead times in the industry. Have a special request? Please contact us. We will do our best to accommodate you.



Don't put off the calibration of your test equipment. It will almost certainly cost you money. A piece of test equipment that is inaccurate can give you false results. False results can cost you. Getting a false reading on a link could mean you are passing a failing link or worse yet failing a passing link.
