TS-R36W High Precision DB VU Level Meter Head 500uA Digital Audio Amplifier Board Indicator Power MeterFeature:A

Electrical performance:Standard test conditions: temperature 20 Celsius, 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 %

B

Internal impedance: 650 ohm ± 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

C

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

D

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

Specification:Pointer swing direction: From left to rightPointer length: 28±1mm from the central axis to the needle endPointer width: 0

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 30cm/11

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 Celsius, 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

Note:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures

Thank you!Please allow slightly measuring deviation due to manual measurement
