VU Meter DB Level Header Amplifier Chassis Audio Preamp with Backlight T-90

Features: *Standard test conditions temperature: 20 ℃, humidity 70% . Can also be tested under normal temperature and humidity. *The influenza degree pointer at the zero scale to the maximum scale sensitivity of 960uA ± 8% (full scale position) internal impedance :650Ω ± 10% *Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell *Electrical insulation of the circuit impedance is 500V DC voltage test of the insulation value. Pointer to overlap with the zero-scale tolerance of ± 1mm balanced meter using a standard position and tilt 90 degrees to allow the error range of ± 1mm pointer to mount the current instant plus three times the full scale current, and slowly reduced to the the electric influenza degree 1/2 reading, *The pointer will return to the scale plate within 1/3 scale friction meter coupled with the current, and slowly increase or decrease to a certain value, indicating the point of error range of ± 1mm,brake instantly plus scale plate 2/3 of the current value of the pointer indicates the location of the time required for a second or less.
