Designing, testing, manufacturing, and servicing frequency converters or inverters requires the use of professional, accurate, and precise measuring instruments. The scope of tasks performed by measurement instruments in the production of converters and inverters is very broad – from working with printed circuit boards and low voltage, to operating with chokes and drives at high current and voltage levels. Many multimeters have calibration certificates and are regularly checked in specialized laboratories.

What measuring instruments are available at Z.E. Twerd? Above all, it is worth noting that these are durable and reliable instruments that have been used at the company for many years. The ones used in servicing are often taken to field locations where they face various, often harsh, environmental conditions such as high or low temperatures, humidity, impacts, and dust. All of this must be endured by the instruments used in the service department.

Years of experience working with different measuring devices have helped narrow down the currently used list at Z.E. Twerd to the most professional, accurate, and reliable instruments, which include:

  • ESL EMI Test Receiver by Rohde & Schwarz
  • Power Quality Analyzer by Chauvin Arnoux
  • Multimeters by Fluke, Brymen, Kyoritsu, Sanwa
  • Oscilloscopes by Tektronix, Owon, Agilent, Rigol
  • Electrical Safety Tester by GW Instek
