General description Current source High-precision ohm meters with an adjustable test current of up to 600 A. For stationary and portable use in switching stations or industrial environments. One current output and three voltage measurement inputs allow the resistance to be measured at three measurement points simultaneously. Used in combination with an ACTAS test system, static and dynamic determination of the main contact resistances is possible.
