This Audio impedance meter is essential for reliable installation of background music and paging systems in residences, offices buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional Volt/Ohm meters, which measure DC resistance, this unit utilizes an internal 1kHz oscillator to measure true impedance.

• Impedance matching volume controls, switchers, transformers and passive crossovers
• Measures up to 20kΩ
• Can be utilized with 25V/50V/70V/100V speaker line transformers in commercial installs (see manual)
• Large digital display features 1" characters for easy viewing
• Rotary selector provides 200Ω, 2kΩ & 20kΩ scales
• Rugged, double insulated case is CATIII rated for use up to 200V
• Requires 8x AA batteries (not included)
• Supplied with test leads, carry case and owners manual
• Dimensions (WxHxD): 178 x 82 x 77mm
