1. Movable part: movable coil type
2. Pointer materials: Nickel Silver Strips
3. Pointer color: Black
4. Direction of pointer swing: From left to right
5. Pointer length: 30+/-1mm from the center axis to the end of the needle
6. Pointer width: 0.45 +/- 0.05mm
7. Direction of use: Vertical
8. Operating temperature limit: -10 degree C to + 60 degree C RH 35 to 85%
9. Storage temperature limit: -20 degree C to + 60 degree C RH 35 to 85%
10. Solder condition: Put the terminal about 3 mm into a tin plate with a temperature of 230 degree C. The placement time is 3.5 seconds. After this test, 7-14 items remain normal.
11. Solder temperature: hold the solder gun at 350a?? for 3.5 seconds, and the front end of the terminal is about 3mm in contact with the solder gun. After this test, items 7-14 remain normal.
12. Anti-static: use dry nylon cloth to test the transparent cover surface in the same direction for three times. Mark the pointer difference below 1/3 of the scale length, and return to zero after three seconds.
13. Light bulb specification: DC12V 12W
Note: Do not put the meter in direct sunlight, and store the meter in the packing box to prevent foreign matter from entering the meter
Electrical Performance
1. Standard test conditions: temperature 20 degree C, humidity 70%, no difference in test results, it can also be tested under normal temperature and humidity.
2. Electric influenza degree: Pointer sensitivity 1mA+/- 5% from zero scale to uppper scale (full scale position)
3. Internal impedance: 50ohm+/- 5%
4. Insulation impedance: above 500V DC plus 50M OHm for the charging circuit of the meter outer box. Insulation impedance between the casing of the meter and the charging circuit is tested at 500V DC voltage.
5. Zero position: the meter is in a standard position. The place where the front end of the pointer is integrated with the zero scale center is the reference. The permissible error of the overlap between the pointer and the zero scale is +/-1mm.
6. Equalization: Permissible error range ??±1mm when the standard position of the meter is tilted 90 degrees before and after use.
7. Stick pointer: instantly add three times the full scale current over current, slowly reduce to 1/2 of the electric flu reading, then the pointer will return to 1/3 of the scale.
8. Friction: The error range of indicating point ??±1mm when the electric current is added to the meter and slowly increased or decreased to a certain value.
9. Braking: Instantly add 2/3 of the current of the dial plate, within one second from the beginning to the position indicated by the pointer.
Special Test
1. Over load test: input ten times the full scale current every five seconds, repeat this action for nine times. Each time is 0.5 seconds, 7 to 14 items remain normal after this test.
2. Vibration test: After the meter is packaged, it is shaken up and down by 4mm every 1,000 times per minute on the vibration plate, 10 minutes in each direction. After this test, 7-14 items remain normal.
3. Impact test: The meter fell from a height of 30cm to a 3cm thick board after being packaged, and the test was conducted in three directions,X.Y.Z, 7-14 items remained normal after this test.
4. Reliability test: Electrofluence limit remains within standard after 100,000 correction point current inputs.
5. Environmental impact test: Temperature 50a??, humidity 85%, lasting 100 hours, after this test 7-14 items remain normal.
6. Terminal tension test: the terminal must bear 1 kg tension, lasting for 60 seconds.
