Post-Amplifier VU Meter P-134 Audio Level DB Header Backlight
Parameters:
*Size: see the product picture;
*Pointer material: Nickel silver strips
*Pointer color: White
*Pointer swing direction: from left to right
*Pointer length: from the central axis to the needle end 70±1mm
*Pointer width: 0.45 ± 0.05 mm
*Meter use direction: vertical
*Current sensitivity: 1000uA ±10%
*Internal impedance: 100Ω ± 10%
*Use / storage temperature limit: -10 ° C to +60 ° C RH 35~85%
1.Test experiment bulb: 4pcs white LED backlight, parallel to PCB (80mA at 3.0 - 3.2V) backlight, voltage can be changed to 12V
2.Soldering conditions: Place the terminal about 3mm into the tin plate at 230°C for 3.5 seconds. After the test, the 7-14 items remain normal.
3.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. After the test, the 7-14 items remain normal.
4. Anti-static: Test with the dry nylon cloth on the surface of the transparent cover in the same direction three times. The difference between the markings on the scale is less than 1/3 of the scale length, and the zero return position after three seconds.
Characteristics:
1. 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.
2. Zero position: The electric meter uses the standard posture. The position where the front end of the pointer is combined with the center of the zero scale is the reference. The tolerance of the pointer and the zero scale overlap is ±1mm.
3. Equilibrium: The allowable error range of the meter when the standard position is tilted 90 degrees back and forth ±1mm
4. Sticker: Instantly add three times the over-current of the full-scale current and slowly reduce it to the reading of the current sensitivity of 1/2. At this time, the pointer will return to the scale of 1/3 of the scale.
5. 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.
6. 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
