Description
2pcs TN-105 Classic McIntosh Lake Blue High Precision VU Meter DB Table Discharge Flat Table Pre-Stage Audio Amplifier Power Meter
Note:
● This is a Water Lake Blue VU Metersuitable for large chassis. After the size is increased, the new model is more suitable for the chassis with a panel width of 430mm. The dial still continues the classic Maijingtu style!
Parameters:
● Pointer material: Zinc White Copper● Pointer color: Black● Pointer swing direction: from left to right● Pointer length: 54 ± 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,it can also be tested under normal temperature and humidity.● Current sensitivity: The pointer is in the zero scale to the maximum scale (full scale position). The sensitivity is 1000 uA ± 10%.● Internal impedance: 500 Ω ± 10%.● Insulation resistance: 500V DC plus 50M ohm or more is used for the outer box of the meter and the electrical circuit. The insulation resistance of the meter shell 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 united is the reference pointer and the zero scale.● Balance: The allowable error range of the meter when the standard position is tilted back and forth by 90 degrees 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 time indicated by the pointer.
Special test:
● Overload test Input ten times the full-scale current every five seconds. This action is repeated nine times. Each time is 0.5 seconds, and the test remains normal.● Vibration test: After packaging, the meter will vibrate 1,000 times up and down 4mm per minute on the vibration plate for 10 minutes in each direction. This test remains 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 mus
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: Put the terminal about 3 mm into a tin plate at a temperature of 230 ° C for 3.5 seconds. The test remains 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: use dry nylon cloth to test three times in the same direction on the surface of the transparent cover● Lamp specifications: four white LEDs 2.8-3.0V (we can change the backlight voltage to 12V for you for free, if you need, please contact, thank you)
After the voltage divider is connected in series, the backlight voltage is changed to 12V, as shown in the figure:
● Note: the square pad is the positive electrode, and the round pad is the negative electrode.
