BulletPoint : Input noise as low as 2 nV Ultra-low noise input stage BJT Gain of 10/20/50/100 200Hz~300kHz gain bandwidth Ultra-compact and portable
BulletPoint1 : 1. Operating temperature limit: -10 ° C to +60 ° C RH 35 to 85%
BulletPoint2 : 2. Storage temperature limit: -20 ° C to +60 ° C RH 35 to 85% Do not place the meter in direct sunlight and store the meter in the box to prevent foreign matter from entering the meter.
BulletPoint3 : 3. Soldering conditions: Place the terminal about 3 mm into the tin plate at 230 °C for 3.5 seconds. Soldering temperature The temperature of the hand-held soldering gun is 350 °C, the terminal is in contact for 3.5 seconds, and the front end of the terminal is about 3 mm in contact with the soldering gun.
BulletPoint4 : 4. Anti-static: Test with the dry nylon cloth on the surface of the transparent cover three times in the same direction. The difference between the markings on the scribe is less than 1/3 of the length of the scale, and the position is returned to zero after three seconds.

ProductDescription : VU METER Parameter: Pointer material: Nickel silver strips Pointer color: black Pointer swing direction: from left to right Pointer length: from the central axis to the needle end 110 ± 1 mm Pointer width: 0.45 ± 0.05 mm Meter use direction: vertical  Electrical performance: 1. Standard test conditions: temperature 20 ° C, humidity 70%, for the test results are not different, can also be tested under normal temperature and humidity 2. Current sensitivity: the pointer is from the zero scale to the maximum scale (full scale position) Sensitivity 1200 uA ± 10% 3. Internal impedance: 2KΩ ± 10% 4. Insulation resistance: 500V DC plus 50M ohm or more for the outer box and electrical circuit of the meter. The insulation resistance of the meter case and the electrical circuit is tested by the 500V DC voltage. 5. Zero position: The standard position of the meter is used. The position where the front end of the pointer is combined with the center of the zero scale is the tolerance of the reference pointer and the zero scale overlap is ±1mm. 6. Equilibrium: The allowable error range of the meter when the standard position is tilted 90 degrees back and forth ±1mm 7. Sticker: Instantly add three times of over-current to the full-scale current and slowly reduce it to a reading of 1/2 of the current sensitivity. At this point, the pointer will return to the scale of 1/3 of the scale. 8. Friction: When the current is added to the meter and slowly increased or decreased to a certain value, the error range of the indication point is ±1mm. 9. Brake: Instantly add the current value of the scale 2/3, within one second from the start to the time required for the pointer to indicate the position  Driver Board Introduction:  The MCU is used to process the audio signal, and the driver board is best for small and medium VU meters (not suitable for large VU meters), match for 0~5Vrms of input level signals. Multi-function setup option, suitable for various occasions.  Supports 3 types of power input, covering most of the power supply voltage, whether it is a household ordinary power supply or taking power from the amplifier itself, it is very easy. Provides 2 kinds of compression levels to choose from, 2x and 4x square compression,match for most of the audio input signal levels can be achieved in a large dynamic range . The driver board is the same as the principle of the professional VU driver IC. It can be matched with a professional meter to achieve accurate level display after calibrated to the 0dB position. Parameter:  1. Audio input: stereo audio (computer,MP3.etc., speaker output that does not support power amplifier)  2. Audio input level: <5Vrms  3. Operating Voltage:  4. 6-12VAC alternating current, 6-12VDC direct current, 200MA.  5. 5VDC,>1.5A.  6. Tungsten lamp backlight voltage: DC10V (adjustable brightness)  7. LED backlight voltage: 5V (adjustable brightness)  8. Pointer acceleration and deceleration damping function: support  9. The pointer fall speed adjustment: FAST/SLOW.  10. Audio compression function: supports 2 times and 4 times square compression.  11. Meter calibration function: support.  12. Size: 70*70mm.  13. Driver board output current: <50mA.
