High Precision VU Panel Meter Header DB Level w/ Backlight
Parameters:
*Size: see the product picture;
*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 33±1mm
*Pointer width: 0.45 ± 0.05 mm
*Meter use direction: vertical
*Internal impedance: 650 Ω ± 15%
*Current sensitivity: sensitivity 500uA ± 10%

1. Test experiment bulb: 12V dim yellow bubble
2. Soldering conditions: Place the terminal about 3mm into the tin plate at 230°C for 3.5 seconds.
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.
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
