Parameters:

Pointers Material:Nickel silver strips

Pointer color:orange

The direction of the pointer swing : left to right

Pointer length :  19.5± 1 mm from the center axis to the needle end

Pointer width :  0.45 ± 0.05 mm

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 300uA ± 10% (full scale position)

internal impedance :800Ω ± 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 influenza

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.

Features:

Tests on each interval of five se conds to ten times the full scale current input overload, the action is repeated nine times for

each time of 0.5 seconds.After this test, 7-14 to maintain normal.

Vibration test meter packaged in the vibration plate 1,000 times per minute, up and down 4mm shock In each direction for

10 minutes. After this test 7-14 to maintain normal impact test meter packaged 30-cm height of fall in 3cm thick wooden

board, XYZ three-direction test.After this test, 7-14 to maintain normal reliability test the current input of 100,000 calibration

points within the limits of current sense is still the standard environmental impact test temperature of 50 ° C, humidity 85%,

for 100 hours, after this test 7-14 to maintain normal.Terminal pull test :terminals must withstand one kilogram tension,

sustained 60 seconds will not be affected.

Package:

2pcs P-40SA Power Amplifier VU Panel Meter

1pc TS-VU003 drive board(This driver board can be directly connected to the output of the amplifier, the output voltage is adjustable, so the connection with the backlight level meter can not add resistance, more convenient)
