Chauvin Arnoux F203 [P01120923] 1000V AC/DC TRMS Clamp Meter. The Chauvin Arnoux F203 Clamp Meter with Carrying Case boasts an adapter function which allows you to take a range of non-electronic measurements, including temperatures up to 1,000 degrees C, and light levels. As well as this, the F203 can also measure resistance levels within a current. The digital clamp meter is capable of automatically detecting whether you are measuring an AC or DC current, and will change its setting accordingly, although there is a manual override function for this feature. The digital clamp-on meter can measure up to 1000 volts in both AC and DC formats, and will beep if continuity is detected. The 6,000-count LCD screen will display a single result after measurements have been taken, although it is possible to manually access minimum and maximum recordings. The screen also has a backlight, meaning it is easily visible, regardless of the lighting or the angle at which you hold it. The meter will also measure in-rush currents. The F203 weighs just 340g and measures 78 x 222 x 42 millimetres, making it an extremely portable piece of equipment. The device also comes with a carry case, meaning you can store, protect and transport the Chauvin Arnoux F203 Clamp Meter with Carrying Case with ease. The device is battery powered, and has an automatic power off feature if left unattended, which will preserve battery life. The F203 has been designed to be used in one hand. Buttons are all located on the front of the device, and each of the buttons has only one function to avoid confusion. The jaws of the clamp are activated through the use of the trigger on the left side of the body.
