2x TR-35 VU Meter Head Power Amplifier DB Table Level Sound Pressure Internal Impedance for Test Temperature | Автомобили и

Features:
Test Temperature
Standard test conditions temperature: 20 ° C, 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 500 uA ± 10% (full scale position).
Internal Impedance
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 The zero position 10 meter using the standard position, one place probe front and zero- Scale center for the benchmark.
Error Range
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.
Mount the Current
Pointer to mount the current instant plus three times the full scale current, and slowly reduced to The the electric force 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.
