Bcowtte 2 x P-134 VU Meter Drive Splatine VU Meter Audio Background Lighting Analogue Digital Power Meter

Features of VU meter: Standard test conditions Temperature: 20 degrees Celsius, humidity 70%. Can also be tested in normal temperature and humidity. The influenza degree on the zero scale to the maximum scale sensitivity of 1000 ± 10% (position at full scale); internal impedance: 800 ohms ± 10%; insulation impedance meter outside the circuit with 500 V DC plus 50 M Ohm meter housing VU meter special test: in tests at any interval from five seconds to ten times the overload of the current input in full, the action is repeated nine times of 0.5 seconds. After this test, 7 to 14 to maintain the normal reading 1000 times per minute in the vibration plate, 4 mm push 10 minutes in the direction up and down. The electrical insulation of the circuit impedance is a 500V test of the insulation value. Overlaps with the zero scale tolerance of ± 1 mm balanced gauge using a standard position and tilts 90 degrees to allow the error range of ± 1 mm; to mount the current moment plus three times the full scale current and slowly reduce to the value of the electrical influenza grade 1/2 reading, The returns to the scale plate within the 1/3 scale friction meter coupled with the current and slowly rises or decreases to a certain value that shows the error point range of ± 1 mm. According to this test 7-14 to maintain a normal impact test meter, packed 30 cm drop height 3 cm thick wooden board, three-direction test. According to this test 7-14 to maintain the normal reliability test, the current input of 100,000 calibration points. Within the limits of the current sense, the standard temperature for the environment is still of 50°C, humidity 85% for 100 hours, after this test 7-14, to maintain normal value
