- ¸ðµ¨ ¹øÈ£: 4pcs P-97 VU Meter
- ÃÖ´ë ä³Î´ç Àü·Â: Àü¿ø ¾øÀ½
- ºê·£µå À̸§: Olive Leaf
- Áõ¸í¼: NONE
- ±Ù¿ø: CN (Á¤Ç°)
Parameters: ¡Ü Pointer material: Nickel silver strips
¡Ü Pointer color: orange
¡Ü Pointer swing direction: from left to right
¡Ü Pointer length: from the central axis to the needle end 54 ¡¾ 1 mm
¡Ü Pointer width: 0.45 ¡¾ 0
Electrical performance£º ¡Ü Standard test conditions: temperature 20 ¡É, humidity 70%, if there is no difference in the test results,can also be tested under normal temperature and humidity
¡Ü Current sensitivity: the pointer is in the zero scale to the maximum scale (full scale position) Sensitivity 1000 uA ¡¾ 10%
¡Ü Internal impedance: 100¥Ø ¡¾ 10%
¡Ü 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.
¡Ü 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 integrated is the reference pointer and the zero scale.
¡Ü Balance: the allowable error range of the meter when the standard position is tilted 90 degrees forward and backward is ¡¾ 1mm
¡Ü 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
¡Ü 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 ¡¾ 1mm
¡Ü 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 pointer
Special test: ¡Ü Overload test: input ten times the full-scale current every five seconds, this action is repeated nine times. Each time is 0.5 seconds
¡Ü Vibration test: After the meter is packaged, it will shake 1,000 times up and down 4mm per minute on the vibration plate for 10 minutes in each direction.
¡Ü Impact test: After the meter is packaged, it falls from a height of 30 cm to a 3cm thick wooden board, X.Y.Z. three directions test
¡Ü Reliability test: after 100,000 calibration point current inputs, the current sensitivity limit is still within the standard
¡Ü Environmental impact test: temperature 50 ¡É, humidity 85%, lasts 100 hours, after this test remains normal
¡Ü Terminal pull test: The terminal must withstand 1 kg of pull for 60 seconds without being affected
The Other£º ¡Ü Operating temperature limit: -10 ¡É to + 60 ¡É RH 35 to 85%
¡Ü Storage temperature limit: -20 ¡É to + 60 ¡É RH 35 to 85%
¡Ü Do not put the meter under direct sunlight, and store the meter in the packing box to prevent foreign matter from entering the meter
¡Ü Soldering conditions: put the terminal about 3 mm into a tin plate at a temperature of 230 ¡É for 3.5 seconds
¡Ü Solder temperature: Hand soldering gun temperature 350 ¡É, contact the terminal for 3.5 seconds, the front end of the terminal is about 3mm in contact with the soldering gun
¡Ü Anti-static: Use dry nylon cloth to test three times in the same direction on the surface of the transparent cover.
¡Ü Lamp specification: 2 blue LED backlights (20mA at 2.9-3.2V), the backlight voltage can be changed to 12V for free, please note
Package include: 4pcs P-97 VU Meter
