The idea of a berühungslosen measurement and clearly signaling I liked.
But short test showed that appears in some cases in spite of the applied voltage of 230V no suspense!
At all wall outlets, no voltage is indicated, for example, at power strips already.
In fuse box voltage is spacious display, but at a single terminal in turn not,
unless you turn the tester 180 ° about its own axis.
Thus, the device is useless and dangerous. This view is confirmed by various descriptions of phase auditors on the Internet.
Secure test is carried out only by two-pole measurement.
The machine was blinking already up in the closed blister. Any disturbance leads to flash and is likely in transit have already been partially emptied the batteries used.
Fluke has not answered me an e-mail request.
