Sell WT 1 Set Vu Meter With Backlight Db Meter Power Meter 45mm Amplifier Volume With Driver Board best price

Instantaneously add the power value of the scale plate full scale value of 23, from the beginning to the index. The time required for the needle to stop swinging. Test the insulation value with 500 DC voltage, the insulation resistance of the meter case and the electrical circuit anti. When the meter rotates 45" in the front, back and clockwise and counterclockwise directions relative to the standard use position. The distance the pointer deviates from the center of the zero mark. Description: Name: Vu Meter Internal DC resistance: 650 ohm + -15%. Calibration position: + 5 Accuracy: Level 5 Continuous Current; 15% UA +- Backlight: LED * 3 Working Temperature: -22%-55 degrees Celsius VU meter backlight voltage: AC6V-12V Features: 1. The temperature is 20C and the humidity is 70%. If there is no difference in the test results, it can also be carried out at room temperature and humidity 2. The meter is in the standard use position, the center of the zero scale line is the reference, and the pointer 3. The DC resistance value of the two wires at the head of the meter. 4. After adding the full-scale power (current or voltage) to the meter, then slowly reduce to zero, the pointer The error between the indicated position and the center of the mechanical zero scale. 5. Input when the meter is in use--The constant power value makes the batch needle stay on the scale plate stably. One position, the difference between the actual power value entered at this time and the nominal value of the meter here is removed. The result obtained with the full scale nominal value. 6. Instantly add the over-charge (current or voltage) of the full-scale current three digits, and slowly after 7 seconds. Reduce to 12 of the full current. At this time, the batch needle may be produced due to different environmental temperature and humidity. There is a phenomenon of licking at the bottom of the raw material, but the batch of needles should be returned to the specified range.
