Product description All-Sun EM480B Audio Impedance Tester EM408B is a precise measurement instrument that specially applied in measuring audio impedance.

Applied in many wide application, such as measuring the impedance of loud speaker, set of sounds system, home theater and commercial audio sytem.

Features: True measurement of speaker systems actual impedance at 1kHz Three test ranges (20Ω / 200Ω / 2000Ω) allow testing of home theater and commercial sound systems.

Convenient portable battery operation.

Low battery indication Data hold function Timer function for easier operation.

The timer can last about 30 seconds minutes after users press TEST button.

Auto power off: after about 15 minutes of non-use For insulation resistance test, you can change the test voltage among 250V,500V and 1000V.

it can also be used to test ACV, resistance which is less than 200Ω, and test for continuity.

You can use it to test transformer, motor, cable, switch, electrical appliance as well as to do insulation resistance test.
