Product Description

Pointers Material:Nickel silver strips
Pointer color:Orange
The direction of the pointer swing : left to right
Pointer length : 30± 1 mm from the center axis to the needle end
Pointer width : 0.45 ± 0.05 mm
Electrical properties:
standard test conditions temperature: 20 ℃, humidity 70% . Can also be tested under normal temperature and humidity
The influenza degree pointer at the zero scale to the maximum scale sensitivity of 500uA ± 10% (full scale position) internal impedance :650Ω ± 10%
Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell
Electrical insulation of the circuit impedance is 500V DC voltage test of the insulation value. Pointer to overlap with the zero-scale tolerance of ± 1mm balanced meter using a standard position and tilt 90 degrees to allow the error range of ± 1mm
pointer to mount the current instant plus three times the full scale current, and slowly reduced to the the electric influenza degree 1/2 reading,
The pointer will return to the scale plate within 1/3 scale friction meter coupled with the current, and slowly increase or decrease to a certain value, indicating the point of error range of ± 1mm, brake instantly plus scale plate 2/3 of the current value of the pointer indicates the location of the time required for a second or less.
Special test:
tests on each interval of five seconds to ten times the full scale current input overload, the action is repeated nine times for each time of 0.5 secondsAfter this test, 7-14 to maintain normal.
terminal pull test :terminals must withstand one kilogram tension, sustained 60 seconds will not be affected.
