Ground and Isolations

Audio impedance meter, meter and insulation resistance tester

• The audio impedance meter allows testing of home speaker systems, auditoriums and public address systems to estimate the necessary power in an installation for the suitable election of the amplifier.
• The meters have two types earth with spades or without spades.
• The insulation tester performs insulation test voltage with a constant charging current of 1 mA, with different scales for strength and insulation resistance.
