General High-precision ohm meter with an adjustable test current of up to 200 A. description The measuring device is equipped with a rechargeable battery for portable use in switching stations and industrial environments. Two current outputs and two voltage measurement inputs allow the resistance to be measured at two measurement points simultaneously. Used in combination with an ACTAS test system, static and dynamic determination of the main contact resistances is possible on 2 main contact chambers per pole.
