VU meter

1. Voltage 500MV, Weight: 21 grams, excellent quality, cute appearance, stable and reliable performance.

2. Header resistance: 652 ohms ( 15B Multimeter )

3.The backlight of bulbs. Operating voltage: 6 ~ 12V AC or .

4. In the backlight brightness to meet the requirements under the conditions, lower operating voltage, can significantly prolong life.

Need to use current limiting resistor in series 100 ohms to 200 ohms, reduce the impact on the filament boot.
