Multimeter Calibration

Multifunction testers also known as MFTs or installation testers are similar to multimeters in terms of functionality yet multifunction testers expand upon the common multimeter by carrying out testing across a much wider spectrum and also include unique testing procedures that you won’t find on common multimeters.

What are multifunction testers used for?

Multifunction testers verify the safety of electrical installations in domestic, commercial and industrial applications. This electrical installation testing ensures that fixed wiring is safe and correctly installed, meeting the requirements of the 17th edition electrical wiring regulations.

Who uses them?

Electricians will use a multifunction tester to stay in line with 17th edition rules and regulations to carry out their test procedures in a timely and efficient manner.

What types of tests are carried out using a multifunction tester?

  • Insulation resistance tests
  • Wiring checks
  • Earth continuity tests
  • Automatic RCDs tests
  • Measure loop impedance and line impedance
  • PSCC (prospective short circuit current) tests to determine required circuit breakers and fuses
  • Socket polarity tests
  • Phase sequence/ rotation checks

Why use a multifunction tester?

Because multifunction testers have the ability to carry out multiple tests without the need to frequently switch between testers when performing an operation, multifunction testers are extremely useful to have inside the toolbox.

Are there different types of multi-function testers available?

Multifunction testers are termed divided up into two categories – downloadable, and non-downloadable. Downloadable multifunction testers are designed to data log using internal memory, allowing users to store test data, communicate data to a PC and use software packages to report, trend and graph the data.

Non-downloadable multifunction testers are generally cheaper in price as they include no internal memory structure, and are designed for simple testing with no memory storage. Instead users must write down results gained.

Do multifunction testers require calibration?

Service and calibration of electrical test equipment is recommended at least once a year. To ensure accuracy and specifications are met, a calibration programme is essential.

Added to the benefits of having equipment looked after by an experienced company in electrical test equipment, Hitek also boasts UKAS capability for electrical testing along with competitive pricing and turnaround times.

Hitek technicians are highly trained and competent to perform calibration services across the UK from the Mobile Calibration Laboratory which goes direct to premises and provides effective on-site calibration.

Onsite service for multifunction testers is available and is proving popular with companies that can’t afford product downtime. Onsite calibration allows equipment to be tested and returned back into service on the same day.

Hitek offer calibration of single function insulation, multi-function, insulation, loop and RCD testers from top manufacturers including Fluke, Megger (MTK, MFT & PPK ranges), Martindale (2500 Part P Testing Kit), Di-Log, Kewtech and ATP.

Hitek also offer a 100 mile radius collection and delivery service to and from the calibration laboratory in Horsham, West Sussex.
