What Is Calibration? The Basics of Calibration

If one of your employees or clients asked you, “What is Calibration?”, would you be able to give them an informed answer? Whatever industrial setting you’re working in, understanding calibration and the requirements of calibration is critical to the safe operation of your equipment and your employees.

You are only as good as the tools you work with. It is essential to understand what is calibration and how certified inspections can ensure your equipment’s longevity. Although you can calibrate and service your tools, it is not advisable to calibrate your own testing equipment without the necessary materials and accreditations. Testing equipment must be in line with manufacturing and industry standards across its whole lifetime. You need to be able to trust your own equipment before you can safely carry out any type of electrical or industrial work.

Power Parameters is Australia’s leading specialists when it comes to equipment calibration. Our testing and repair services provide our clients with the assurance of accurate, efficient and safe to use equipment tested against the highest standards. We can test and calibrate an extended range of products including power supply equipment, electrical testing and measurement tools, power testing gear and more. If you need reliable and precise equipment, Power Parameters are here to help guarantee outstanding performance.

As such, we’re here to break down the question of “what is calibration?”, so that you, your employees, your clients and your colleagues can better understand the importance of calibration and what’s involved in the process.


What is Calibration Testing Defined As?

To provide a calibration definition, it is the process of determining the relationship between an instrument’s measurement method against its output of values.

What is Calibration’s Role in Ensuring Correct Function?

All equipment degrades over time; there is no denying it. The equipment’s internal technology and its frequency of use will determine a specific product’s degradation rate. An electronic device consisting of resistors, capacitors and solid-state components often degrade due to heat, cold and radiation exposure. Mechanical or hydraulic components also suffer from exposure to temperature as well as oxidisation and exposure to chemicals. The deterioration of these components and devices also reduces their measurement accuracy and will eventually exceed acceptable tolerances.

Calibration is vital as it will compensate for this degradation to ensure the equipment’s efficient and correct function. A circumstance will eventuate where calibration cannot keep an instrument within tolerance and repairs, and replacement may be required. Eventually, a new piece of equipment will need to be purchased. In the meantime, regular calibration of industrial equipment is key to ensuring the correct and accurate performance of such equipment.


What Is Calibration Testing? 

At Power Parameters, we operate with one of Australia’s leading NATA Accredited calibration laboratory, specific for calibration testing.

Once the equipment has been received by us and taken to our specialist laboratory, the first step is to conduct a calibration test. This is typically done by measuring samples with known values to determine the accuracy of the instrument. Multiple samples with different values will be used to test the product’s accuracy across its operating range.

The more samples you use in the process results in a higher level of precision. At Power Parameters, we use an appropriate number of samples to ensure precise calibration whilst delivering a reasonable and fair price for this process.

How Is Calibration Conducted?

Once initial calibration testing has begun, the technician will adjust the instrument being tested to align with the base values. This establishes points of reference within the equipment’s’ system of measurement to provide precise readings across its range of operation.

How Calibration Is Performed for Different Tools

We are experts in calibration definitions, and although calibration methods and needs vary between products, the goal of the process is always the same. It is essential to calibrate an instrument to reduce errors and ensure reliable measurements in occupations where precision is vital.

At Power Parameters, we specialise in the calibration of:

DC & Low-Frequency Electrical Metrology

  • Electrical instrument calibrators: DC and AC current, DC and AC voltage, resistance
  • Electrical measurement and test equipment: Ammeters, current clamps, ohm meters, AC and DC voltmeters
  • Electrical Standards: Voltage standard cells and EMF reference devices; conductance boxes, precision resistors and resistance boxes; AC/DC transfer instruments

Temperature Metrology

  • Base metal thermocouples

Time, Frequency And Waveform Metrology

  • Frequency meters and analysers; counters; tachometers; stroboscopes

How Often Do I Need to Calibrate My Instruments?

Calibration needs to be conducted periodically in line with manufacturer and industry standards. A calibration schedule must be maintained to ensure correct function. Other instances where calibration may be required include:

  • The commencement of a significant measuring project – If you are about to undertake a substantial body of work that requires highly accurate measurements it can be a good idea to calibrate the selected tools for the job to ensure they are up to scratch.
  • The conclusion of a significant measuring project – It could be useful to send the same equipment back for testing and calibration to confirm the accuracy of your results for that project.
  • After an accident/critical event – If an incident occurs that affects your equipment’s operation and precision, it is advised you check its accuracy. Examples include a physical impact, system overload or short.
  • After Repairs – If your equipment has required the replacement of parts or undergone significant repair, it is also advisable to perform the calibration.

Although some may view calibration as an expensive and tedious process, the importance of accurate data is second to none. Many hours of time and effort can go to waste if incorrect measurements are identified, a well-maintained calibration schedule has the potential to save you from many hours of lost work. 

What Does Calibrating an Instrument Mean?

What is calibration in maintaining the accuracy of industrial, power, electrical and temperature equipment? Calibration is essential. Our processes will check your equipment against regularly accredited NATA standards to ensure operation within manufacturing specifications. Both of these bodies will detail acceptable tolerances for these products to ensure acceptable standards across the board.

Calibrations conducted by a certified technician provide you with the guarantee that your equipment is running efficiently and is safe to use. Our number one priority is that the equipment we service is precise, and our customers are safe when working with them.

When booking equipment for calibration, it is essential to choose qualified technicians for calibration services. If the equipment is incorrectly calibrated, it could display in inaccurate readings. As a result, your work could suffer or become potentially dangerous.
