You need your test equipment to provide good and usable results from your testing. Test equipment can be used for a process as simple as determining the presence or absence of electric voltage or as complex as automatically testing and diagnosing faults in sophisticated radar and wireless communication equipment. In the same way that your electronic equipment needs testing, your test equipment needs calibration.

Calibration is a comparison between measurements: one of known magnitude or correctness (a standard) and another unit under test (your test equipment). Calibration also includes the process of adjusting the test equipment to comply with the standard. Without calibration things will go wrong:
Test equipment is used to check the proper operation of the device under test, however, what if the test equipment itself is not accurate. You should expect that upon purchasing new test equipment, it has undergone calibration from the manufacturer, and a certificate is attached to prove this process. The same thing goes for used test equipment.
A calibrated machine is a proof that your test equipment is well-maintained and undergoes regular servicing; this will increase the confidence that you and your customers will have in the test equipment and its results. Calibration needs to be performed regularly to make sure that the test equipment performs within accepted standards.
Calibration helps assure the quality of your test equipment during operation, you avoid downtime that will disrupt your regular operations, and hence, avoiding missed schedules or commitments. The same with maintenance, regular calibration is able to expose any potential issues before they become big problems.
You risk the safety of people directly or indirectly using your test equipment. For instance, if uncalibrated test equipment was used to check the acceptable temperature in a food storage facility, it may cause food spoilage (and eventually food poisoning) or have workers operate in uncontrolled temperatures of the facility.
Wasted time and effort
An uncalibrated piece of test equipment can result in poor quality and rejected products or services. You waste time, money and resources to produce the incorrect results. This creates a situation that requires additional efforts to reproduce the needed testing for the product or service to meet the acceptable standards.
Your customers depend on your products and services, and they are expecting that you provide a consistent outcome of good and reliable results. When a product or service does not meet its intended use or is considered inferior, customers will look for a replacement and you lose your reputation for quality.
Poor quality, rework and unsatisfied customers all add up to financial detriment. When test equipment is regularly calibrated you avoid the cost of equipment failure causing downtime and inaccurate results causing reliability issues.
To improve the quality of the calibration and have the output accepted by organizations, the calibration must be traceable to international standards. The National Institute of Standards and Technology (NIST) is a non-regulatory federal agency that has calibration services designed to help manufacturers and users of precision instruments achieve the highest possible level of quality and productivity for measurement equipment.
Technical Diagnostic Services (TDS) offers Test Equipment Calibration; it guarantees reliable NIST-traceable calibration services. TDS’ calibration and verification services include performance verification and adjustments to ensure the equipments’ performance and accuracy meet the manufacturers’ specifications and comply with the highest possible quality standards.
It’s important to have your test equipment undergo regular maintenance service and re-calibration. Whether you are using test equipment for your client’s facilities or acquiring test equipment for your own business, calibration is an essential process that should not be ignored.
