Description
100% brand new and high quality
Features:
Model:TS-DB90R
Pointer material: zinc white copper
● Pointer color: black
● Pointer swing direction: from left to right
● Pointer length: from the central axis to the needle end 44 ± 1mm
● Pointer width: 0.45 ± 0.05 mm
● Meter use direction: vertical
● Internal impedance: 650 Ω ± 10%
● Current sensitivity: sensitivity 960uA ± 8%
● Operating / Storage temperature: -10 ° C to + 60 ° C RH 35 to 85%
● Test experiment bulb: 12V dim yellow bubble
● Soldering conditions: Place the terminal about 3mm into the tin plate at 230 ° C for 3.5 seconds. After the test, the 7-14 items remain normal.
● Soldering temperature: The temperature of the hand-held soldering guns 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 guns. After the test, the 7-14 items remain normal.
● Anti-static: Test with the dry nylon cloth on the surface of the transparent cover in the same direction three times. The difference between the markings on the scale is less than 1/3 of the scale length, and the zero return position after three seconds.
Electrical performance:
● Standard test conditions: temperature 20 ℃, humidity 70%, if there is no difference in the test results, the test can also be performed at normal temperature and humidity.
● Current sensitivity: the pointer is in the zero scale to the maximum scale (full scale position) Sensitivity 960uA ± 8%.
● Internal impedance: 650 Ω ± 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.
● 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, within one second from the start to the position indicated by the pointer
verticalˈvərtikəl.
Special Test:
● Overload test Input ten times the full-scale current every five seconds, and this action is repeated nine times. Each time is 0.5 seconds, and the test remains normal.
● Vibration test: After the meter is packaged, vibration is carried out on the vibration plate 1,000 times per minute up and down 4mm, 10 minutes per 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 30 cm on a 3cm thick wooden board. The X.Y.Z. three-direction test is normal.
● Reliability test: After 100,000 times of current input to the calibration point, the current sensitivity limit is still within the standard Environmental impact test Temperature 50 ℃, humidity 85%, lasts 100 hours, after this test remains normal.
● Terminal pull test The terminal must withstand a 1 kg pull for 60 seconds without being affected.
Note:
Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!
