2. Electrical performance
Standard test conditions: temperature 20C*, humidity 70%. If there is no difference in test results, it can also be carried out in normal temperature and normal humidity environment
1 current sensitivity
The DC current required by the pointer from the zero scale to the position shown on the scale plate
2 maximum current sense cycles
The DC current required by the pointer from the zero scale to the full scale position of the scale plate
Standard: 1mA ± 10%
3 Internal DC resistance Standard: 1002 ± 10%
4 Insulation resistance
Test its insulation value with 500V DC voltage, the insulation resistance of the electric shell and the electric circuit
Standard 50MΩ or more
5 friction
After adding the sensitivity current to the electric insert, slowly reduce it to zero, the error between the pointer indicating position and the center of the zero scale is ±1mm
6 zero position
The electric bit is in the standard position, the center of the zero scale is the benchmark, and the offset between the position of the pointer and the center of the zero scale is ±1mm
7 Balanced
When the electric inlay is inclined forward and backward by 90 degrees relative to the standard position, the deviation between the position of the pointer and the center of the zero scale is ±1mm
8 pointer stick
Instantaneous overcurrent that is three times the full-scale current. After 7 seconds, it gradually reduces to 1/2 of the full-scale current, which means one-half of the full scale at this time. within range
1/2 range
9 pointer swing
The maximum current is added within 5 seconds in a linear manner, and then reduced to zero in a linear manner within 5 seconds. Abnormal conditions such as no stop of the hand swing
