Descriptions：

* Standard test conditions temperature: 20 ℃, humidity 70%. Can also be tested at normal temperature and humidity.

* The influenza degree pointer on the zero scale at the maximum scale sensitivity of 300 uA ± 10% (full scale value) Internal impedance: 800 Ω ± 10%.

* Insulation impedance meter outside the box plus circuit with 500 V DC plus 50 M ohm meter case.

* Electrical insulation impedance of the circuit is 500 V DC. Pointer to overlap with the zero tolerance of ± 1 mm when using a standard position and tilt 90 degrees to allow an error range of ± 1 mm.

* Pointer to measure the current moment plus three times the scale current and slowly reduce to the measured value of the electrical influence degree 1/2,

* Pointer returns to the scale plate within the 1/3 friction meter coupled with the current, and slowly increase or decrease to a certain value, indicating the error range of ± 1 mm for a second or less needed.

Packages:

2pcs TN-90A VU instrument panel

1pc TS-VU003 VU Panel Meter Driver Board(This driver board can be directly connected to the output of the amplifier, the output voltage is adjustable, so the connection with the backlight level meter can not add resistance, more convenient)
