Electrical performance
6 Standard test conditions Temperature 20°C, humidity 70%, if there is no difference in test results,
It can also be tested at normal temperature and humidity
7 Current sensitivity Pointer at zero scale to maximum scale (full scale position) Sensitivity 500 uA ± 10 %
8 Internal impedance 650 Ω ± 10 %
9 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 electrical circuit is tested with a DC voltage of 500V.
10 Zero position The meter uses the standard posture, and the point where the front end of the pointer and the center of the zero scale are unified is the reference
The allowable error of the overlap between the pointer and the zero scale is ±1mm
11 Balance The allowable error range of the meter is ±1mm when the standard position is tilted forward and backward by 90 degrees
12 Pointer sticking Instantly add three times the overcurrent of the full-scale current, and slowly reduce to the reading of 1/2 of the current sensitivity,
At this point, the pointer will return to the 1/3 scale range of the scale plate.
13 Friction When the current is added to the meter and gradually increases or decreases to a certain value, the error range of the indicating point is ±1mm
14 Brake 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
15 Overload test Input ten times the full-scale current every five seconds, this action is repeated nine times. Each time is 0.5 seconds
After this test, 7-14 items remain normal
16 Vibration test After packaging, the meter is subjected to 1,000 vibrations per minute up and down 4mm on the vibration plate.
10 minutes in each direction. After this test, 7-14 items remain normal
17 Shock test After the meter is packaged, drop it on a 3cm thick wooden board from a height of 30cm, X.Y.Z. three-direction test
After this test, 7-14 items remain normal
18 Reliability test After 100,000 times of calibration point current input, the current sensitivity limit is still within the standard
19 Environmental impact test Temperature 50°C, humidity 85%, lasting 100 hours, after this test 7-14 items remain normal
20 Terminal pull test The terminal must bear 1kg pulling force for 60 seconds without being affected
other
21 Operating temperature limit -10℃ to +60℃ RH 35 to 85%
22 Storage temperature limit -20℃ to +60℃ RH 35 to 85%
Do not place the meter in direct sunlight, and store the meter in a box to prevent foreign objects from entering the meter
23 Soldering conditions Place the terminal about 3 mm into a tin plate with a temperature of 230°C, and place it for 3.5 seconds
After this test, 7-14 items remain normal
Solder temperature Hold the solder gun at 350°C, touch the terminal for 3.5 seconds, the front end of the terminal is about 3mm in contact with the solder gun
After this test, 7-14 items remain normal
24 Anti-static Use dry nylon cloth to test the surface of the transparent cover three times in the same direction, and the difference between the pointers on the score is the length of the scale
1/3 or less, return to the zero position after three seconds
25 Bulb Specifications Lamp Cannon 12V 55mA
