Phase rotation indicator. Phase rotation indicator with electronic turntable, frequency display and display of the nominal mains voltage. Phase rotation indicator that complies with safety regulations. Many users prefer the turntable based on the Ferraris principle, which involves a lot of mechanics. This requires a certain volume, which in turn would result in a large housing for the corresponding clearance and creepage distances. We have therefore chosen the electronic turntable for our phase rotation indicator METRAPHASE 1. With LEDs arranged in a circle, not only is the direction of rotation simulated, but the frequency of the mains in which the measurement is being taken is also displayed by LEDs that light up in different colors in this circle. The presence of the respective phase voltage is indicated as required by additional LEDs, as is the nominal voltage of the network.This new phase sequence indicator can be used as a three-pole and two-pole indicator.Power supply: 4 x Mignon cells IEC LR 6. 1 phase sequence indicator3 attachable measuring leads with touch-protected plugs 600 V CAT IV 10 A3 measuring probes for attaching to touch-protected plugs 1000 V CAT IV 1 A / 1000 V CAT II 32 A1 crocodile clip for attaching to touch-protected plugs 600 V CAT IV 19 A4 batteries1 operating manual1 transport case
