Measurement of the current input, power and starting current for a refrigeration system using the testo 770-3 clamp meter.

In a short video, Andreas Dahms (Graduate refrigeration and air conditioning engineer (Dipl.-Ing. für Kälte- und Klimaanlagen), will show you how easy and safe it is to take measurements on a refrigeration system using the testo 770-3 clamp meter.

The testo 770-3 is an effective clamp meter offering the following advantages:

  • Easy, safe measurement of the current, even on electrical cables packed close together without needing to touch them thanks to the innovative clamping mechanism
  • Measurement of current input, starting current (inrush) and motor outputs, including the power factor (cos pi)
  • Improved TRMS method
  • Auto AC/DC
  • Large two-line display
  • Document and send measuring values via Bluetooth and testo Smart App on your smartphone
