The Testboy TV 800 is a device for testing the contact resistance of a line or connection using a test current of 2 mA or selectable 200 mA, in accordance with EN 61557-4. A voltage test up to 300V AC/DC is also integrated, as well as calibration of the test leads. The integrated LED serves as a torch or as an optical signal during continuity testing. The existing non-contact voltage sensor on the back of the device is used to reliably find interruptions in lines.
