Description
2pcs P-55SI VU Meter + 1pcs Driver Board High Precision Head DB meter Amplifier Audio Level Meter with Backlight
Parameters：
● Pointer material:Nickel Silver Strips● Pointer Color: Black● Pointer swing direction: from left to right● Pointer length: 28 ± 1 mm from the center axis to the needle end● Pointer width: 0.45 ± 0.05 mm● Electric meter use direction: Vertical
Electrical performance:
● Standard test conditions: temperature 20 ℃, humidity 70%, if there is no difference in the test results, the test can also be performed at normal temperature and humidity.● Current sensitivity:Pointer from zero scale to maximum scale (full scale position) Sensitivity 250 uA ± 10 %● Internal impedance: 650 Ω ± 10 %.● Insulation resistance: 500V DC plus 50M ohm or more for the outer box of the meter and the electrical circuit. The insulation resistance of the meter housing and the electrical circuit is tested by 500V DC voltage.● Zero position: the standard position of the meter is used, and the point where the front of the pointer and the center of the zero scale are unified is the reference pointer and the zero scale overlap. The tolerance is ± 1mm.● Balance: The allowable error range of the meter when the standard position is tilted 90 degrees forward and backward is ± 1mm.● The pointer sticks: When the full-scale current triples the overcurrent in an instant and slowly reduces to the current sensitivity reading of 1/2, the pointer will return to the scale of 1/3 of the scale.● Friction: When the current is added to the meter and slowly increased or decreased to a certain value, the error range of the indicated point is ± 1mm.● Braking: instantly add 2/3 of the current value of the scale plate, within one second from the start to the position indicated by the pointerverticalˈvərtikəl.
Special Test:
● Overload test: input ten times the full-scale current every five seconds, the action is repeated nine times. Each time is 0.5 seconds, after this test remains normal● Vibration test: After the meter is packaged, perform 1,000 vibrations up and down 4mm per minute on the vibration plate for 10 minutes in each direction. After this test, 7-14 items remain normal.● Impact test: After the packaging of the electric meter, it is dropped from a height of 30 cm on a 3cm thick wooden board. The X.Y.Z. three-direction test is maintained after this test.● Reliability test: After 100,000 calibration point current inputs, the current sensitivity limit is still within the standard.● Environmental impact test: temperature 50 ℃, humidity 85%, lasts 100 hours, after this test remains normal.● Terminal pull test: The terminal must withstand 1 kg of pull for 60 seconds without being affected.
The Others:
● Operating temperature limit: -10 ℃ to + 60 ℃ RH 35 to 85%● Storage temperature limit: -20 ℃ to + 60 ℃ RH 35 to 85%● Do not put the meter under direct sunlight, and store the meter in the packing box to prevent foreign matter from entering the meter.● Soldering conditions Place the terminal about 3 mm in a tin plate at a temperature of 230 ° C for 3.5 seconds, and keep it normal after this test.● Solder temperature: Hold the soldering gun temperature at 350 ℃, contact the terminal for 3.5 seconds, and the front end of the terminal is about 3mm in contact with the soldering gun. This test remains normal.● Anti-static: dry nylon cloth is tested three times in the same direction on the surface of the transparent cover, and the difference between the pointers on the score is less than 1/3 of the scale length, and the position returns to zero after three seconds.● Bulb specifications: 3pcs yellow LED PCBs in parallel 1.8-2.0V 60mA (We can change the backlight voltage to 12V for free.
