Sergey Pasechnikov spent 5 years in the US army where he worked as a specialist in equipment testing, surveying and diagnostics, gaining his first experience in electronic metrology. He then decided to work in a private dimensional laboratory, which later joined the Trescal Group in 2011. Sergey has become a recognised expert in the dimensional field. He has trained numerous technicians and shared his experience with other laboratories in the USA. According to him, “dimensional calibration of equipment requires a real understanding of physical phenomena, and a certain mental agility specific to engineering”. His work philosophy is based on the idea that any task can be done better, more quickly and more easily if you understand it and master all the tricks of the trade.
