Features:
The EM480B Audio Impedance Tester is a versatile and portable device designed for accurate measurement of speaker system impedance at 1kHz. Ideal for both home theater and commercial sound systems, it features three test ranges (20Ω / 200Ω / 2000Ω) to cater to different testing needs. This uv light meter ensures precise readings with its convenient battery operation and additional functionalities.
- True measurement of speaker systems actual impedance at 1kHz.
- Three test ranges (20Ω / 200Ω / 2000Ω) for diverse testing applications.
- Portable and convenient battery operation.
- Low battery indication to avoid unexpected power loss.
- Data hold function to freeze readings for easy recording.
- Timer function that holds measurements for about 30 seconds after the TEST button is pressed.
- Auto power-off feature after about 15 minutes of non-use to conserve battery life.
The EM480B can also perform insulation resistance testing with adjustable test voltages (250V, 500V, 1000V), as well as AC voltage, resistance less than 200Ω, and continuity testing. It is commonly used for testing transformers, motors, cables, switches, electrical appliances, and insulation resistance.
