The Metraline RLO-Check is a digitally displaying low-resistance measuring device for the safe checking of line resistances up to 20Ω in electrical systems with nominal voltages of up to 500V.
Metraline RLO-Check is suitable for quick and safe checking of larger protective conductor, earthing and equipotential bonding conductors, as well as shielding and lightning protection systems.
The measured value is displayed on the red (poor) or blue (good) backlit digital display. In addition, a value <1Ω can be signaled with a buzzer.
