P-134 VU Meter DB Sound Level Meter Backlight Same Style For Accuphase Speaker Fit Power Amplifier

P-134 VU Meter DB Sound Level Meter Backlight Same Style For Accuphase Speaker Fit Power Amplifier

Description:
The new high-precision P-134 large-size VU meter boasts dial style based on the classic style for Accuphase. After power on, the hollow fonts on the pure white homogenizing board are crystal clear and very beautiful!

Appearance and structure:
1. Movable part: moving coil type
2. Appearance size: check details below
3. Degree board: check details below
4. Pointer material: Nickel silver strips. Pointer color: white. Pointer swing direction: from left to right. Pointer length: from central axis to needle end 70±1mm. Pointer width: 0.45±0.05 mm
5. The direction of use of the electric meter: vertical

Electrical performance:
6. Standard test conditions: 20℃, humidity 70%. As long as there is no difference in the test results, the test can also be carried out at room temperature and humidity
7. Current sensitivity: the pointer is at the zero scale to the maximum scale (full scale position), the sensitivity is 1000uA±10%
8. Internal impedance: 100Ω± 10%
9. Insulation resistance: 500V DC plus 50M ohm or more for the outer box of the meter and the electrical circuit. The insulation resistance of the meter case and the electrical circuit is tested with a 500V DC voltage.
10. Zero position: The meter uses the standard posture, and the place where the front end of the pointer and the center of the zero scale are combined is the reference. The overlap tolerance of the pointer and the zero scale is ±1mm
11. Balance: the allowable error range of the meter is ±1mm when the standard position is tilted forward and backward by 90 degrees
12. Pointer sticking: Instantly add the full-scale current three times the overcurrent, and slowly decrease to the reading of the current sensitivity 1/2, at this time the pointer will return to the 1/3 scale range of the scale board
13. Friction: When adding current to the meter, and slowly increasing or decreasing to a certain value, the error range of the indication point is ±1mm
14. Braking: Instantly add 2/3 of the current value of the scale plate, within one second from the start to the pointer position

Special test:
15. Overload test: Input ten times the full scale current every five seconds. This action is repeated nine times. Each time is 0.5 seconds. After this test, items 7-14 remain normal
16. Vibration test: After the electric meter is packaged, it performs 1,000 up and down 4mm vibrations per minute on the vibrating plate, 10 minutes in each direction. After this test, the 7-14 items remain normal
17. Impact test: After being packaged, the meter is dropped from a height of 30 cm on a 3cm thick wooden board, tested in X.Y.Z. three directions. After this test, the 7-14 items remain normal
18. Reliability test: After 100,000 calibration point current input, the current sensitivity limit is still within the standard
19. Environmental impact test: 50℃, humidity 85%, lasting 100 hours, after this test 7-14 items remain normal
20. Terminal pull test: The terminal must withstand a pull of 1 kg for 60 seconds without being affected

Others:
21. Operating temperature limit: -10℃ to＋60℃, RH 35% to 85%
22. Storage temperature limit: -20℃ to＋60℃, RH 35% to 85% (Not place the meter under direct sunlight, and store the meter in the packing box to prevent objects from entering the inside of the meter)
23. Soldering condition: Put the terminal about 3 mm into a tin plate at 230℃ for 3.5 seconds. After this test, items 7-14 remain normal. Soldering temperature: Hold solder gun at 350℃, and touch the terminal for 3.5 seconds , The front end of the terminal is about 3mm in contact with the solder gun. After this test, 7-14 items remain normal
24. Anti-static: Use a dry nylon cloth to test three times in the same direction on the surface of the transparent cover. The difference of the pointer on the marking is less than 1/3 of the length of the scale, and it will return to the zero position after three seconds.
25. Bulb specifications: 4 white LED backlights, connected in parallel to the PCB (80mA at 3.0-3.2V) (Note: backlight voltage can be changed to 12V for free, please contact us if needed)

Package Included:
- 1 x Set of VU Meter
