TN-65 VU Panel Meters DB Level Header Detectors Chassis w Backlight

Parameters：

Pointers Material:Zinc white copper

Pointer color:Black

The direction of the pointer swing : left to right

Pointer length :  30± 1 mm from the center axis to the needle end

Pointer width :  0.45 ± 0.05 mm

Features：

*Standard test conditions temperature: 20 ℃, humidity 70% . Can also be tested under normal temperature and humidity

*The influenza degree pointer at the zero scale to the maximum scale sensitivity of 280uA ± 10% (full scale position) internal impedance :600Ω ± 10%

*Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell

*Electrical insulation of the circuit impedance is 500V DC voltage test of the insulation value. Pointer to overlap with the zero-scale tolerance of ± 1mm balanced meter using a standard position and tilt 90 degrees to allow the error range of ± 1mm

*pointer to mount the current instant plus three times the full scale current, and slowly reduced to the the electric influenz degree 1/2 reading,

*The pointer will return to the scale plate within 1/3 scale friction meter coupled with the current, and slowly increase or decrease to a certain value, indicating the point of error range of ± 1mm,brake instantly plus scale plate 2/3 of the current value of the pointer indicates the location of the time required for a second or less.
