Flir’s AccuTip™ Technology
You may not have heard of AccuTip™ technology because it is brand new in the CM4X ClampMeter Family. Small gauge wire measurements have never been more accurate. The CM46 leads them into the tenth of a digit where their numbers count for something. Plus MAX/MIN/AVG recording, that comes standard, no pencil and paper required.
