Note：

● The internationally renowned brand ALLEN & HEATH, a professional electro-acoustic equipment manufacturer, the number of original meter heads is not much, don't miss the goods! ● Due to the restriction of the foreign trade agreement, the dial is not equipped with the original LOGO, the others are exactly the same, and the manufacturer is not allowed to circulate the header with its own LOGO in the market at will! ● The dial is reserved for the installation position of the PEAK lamp (peak indicator). There are two ways to choose from the external PEAK lamp and the internal PEAK lamp: ①External PEAK lamp circuit: if the meter has the PEAK lamp function, you need to provide your own supporting circuit; ②Built-in PEAK lamp circuit: The PEAK lamp circuit is attached to the meter head, and it can work by connecting the VU meter driver board of our shop.Link is https:/item/4000996156724.html

Parameters:

● Pointer material: Nickel silver strips ● Pointer color: black ● Pointer swing direction: from left to right ● Pointer length: 30 ± 1 mm from the central 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%, for the case of no difference in test results,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) Sensitivity 280uA ± 10% ● Internal impedance: 600ohm ± 15% ● 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. 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. ● 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, and the time required from the start to the position indicated by the pointer is within one second.

Special test:

● Overload test: input ten times of full-scale current every five seconds, this action is repeated nine times. Each time is 0.5 seconds ● 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. ● 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 ● Reliability test: After 100,000 correction 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 7-14 items remain 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: Put the terminal about 3 mm into a tin plate at a temperature of 230 ℃ for 3.5 seconds ● Soldering temperature: the temperature of the hand soldering gun is 350 ℃, contact the terminal for 3.5 seconds, and the front end of the terminal is about 3mm in contact with the soldering gun ● 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 ● Lamp specification: Lamp 12V 55mA
