2pcs P-40SA VU meter DB Amp Level Header Level Audio Meter With Blue LED Backlight
Feature:
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.
Special test:
Tests on each interval of five seconds 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.
Others:
Temperature limits for using:-10 ℃ to +60 ℃ RH 35 to 85%
Temperature limits for Storage:-20 ℃ to +60 ℃ RH 35 to 85%
-----Do not use the meter in direct sunlight, and put the meter in the box to avoid foreign matter into the meter internal.
Soldering Condition terminal about 3 mm placed in the temperature of 230 ℃ tin plate, placed 3.5 seconds.
After this test, 7-14 to maintain normal,
Hand-held
soldering gun to solder temperature 350 ℃, the terminal contact for 3.5
seconds, the terminal front-end of about 3mm contact with the solder
gun.
After this test, 7-14 to maintain normal,
anti-static test in
the same direction three times, to characterize the difference between
the pointer in the length of the scale in a transparent cover surface to
dry nylon 1/3 back to the zero position.
