2pc P-97 Audio Volume Unit indicator Peak AMP DB Level Meter w/1pc Driver Board

Description

2pc P-97 Audio Volume Unit indicator Peak AMP DB Level Meter w/1pc Driver Board
Parameters:
Pointer material: Nickel silver strips
Pointer color: orange
Pointer swing direction: from left to right
Pointer length: from the central axis to the needle end 54 ± 1 mm
Pointer width: 0.45 ± 0.05 mm
Meter use direction: vertical
Electrical performance:
1. Standard test conditions: temperature 20 ° C, humidity 70%, for the test results are not different, can also be tested under normal temperature and humidity
2. Current sensitivity: the pointer is from the zero scale to the maximum scale (full scale position) Sensitivity 1000 uA ± 10 %
3. Internal impedance: 100Ω ± 10%
4. Insulation resistance: 500V DC plus 50M ohm or more for the outer box and electrical circuit of the meter. The insulation resistance of the meter case and the electrical circuit is tested by the 500V DC voltage.
5. Zero position: The standard position of the meter is used. The position where the front end of the pointer is combined with the center of the zero scale is the tolerance of the reference pointer and the zero scale overlap is ±1mm.
6. Equilibrium: The allowable error range of the meter when the standard position is tilted 90 degrees back and forth ±1mm
7. Sticker: Instantly add three times of over-current to the full-scale current and slowly reduce it to a reading of 1/2 of the current sensitivity. At this point, the pointer will return to the scale of 1/3 of the scale.
8. Friction: When the current is added to the meter and slowly increased or decreased to a certain value, the error range of the indication point is ±1mm.
9. Brake: Instantly add the current value of the scale 2/3, within one second from the start to the time required for the pointer to indicate the position
Special test:
1. Overload test Ten times the full scale current input every five seconds, this action is repeated nine times. Each time is 0.5 seconds, after which 7-14 items remain normal.
2. Vibration test: After the meter is packaged, it will be subjected to 1,000 times per minute and 4 mm vibration on the vibrating plate for 10 minutes in each direction. After the test, 7-14 items remain normal.
3. Impact test: After the meter is packaged, it will fall from the height of 30 cm to the 3cm thick board, X.Y.Z. three-way test, after which 7-14 items remain normal.
4. Reliability test: After 100,000 calibration point current input, the current sensitivity limit is still within the standard
5. Environmental impact test: temperature 50 ° C, humidity 85%, for 100 hours, 7-14 items remain normal after this test
6. Terminal pull test: The terminal must withstand 1 kg of pulling force for 60 seconds without being affected.
Other:
1. Operating temperature limit: -10 ° C to +60 ° C RH 35 to 85%
2. Storage temperature limit: -20 ° C to +60 ° C RH 35 to 85%
Do not place the meter in direct sunlight and store the meter in the box to prevent foreign matter from entering the meter.
3. Soldering conditions Put the terminal about 3 mm into the tin plate at 230 °C for 3.5 seconds.
4. Soldering temperature The temperature of the hand-held soldering gun is 350 °C, the terminal is in contact for 3.5 seconds, and the front end of the terminal is about 3 mm in contact with the soldering gun.
5. Anti-static: Test with the dry nylon cloth on the surface of the transparent cover in the same direction three times. The difference of the pointer on the scribe is less than 1/3 of the length of the scale, and the position returns to zero after three seconds.
6. Lamp specifications: 2 blue LED backlights (20mA at 2.9 - 3.2V) can be changed to 12V for free
