[Scope of application]: Used to measure the resistance value with a certain density under a certain geometric shape, and then convert it into the specific resistance value of the fiber according to the filling degree of the fiber
[Related standards]: GB/T 14342-1993 "Synthetic short fiber specific resistance test method"
【technical parameter】:
1. Measuring range of fiber specific resistance: (reduced resistance value) 106~1013Ω, 15g of test sample each time.
2. The basic error of the instrument to the standard resistance measurement is ≤±20%.
3. The instrument should be used in an environment without corrosive gas and strong electromagnetic field interference.
4. The instrument should be calibrated under standard environmental conditions with a temperature of 20℃±2℃ and a relative humidity of 65±10%.
5. The working power supply is AC 220±10%, 50Hz.
6. The test voltage of the instrument is divided into two levels: 50V and 100V, the voltage deviation is less than ±0.5%, and the voltage stability is less than ±0.5%.
7. When the instrument is at a stable working voltage and no signal input, after 1 hour of power-on, the zero drift within 8 hours is not more than ±4% of the full scale.
8. The insulation resistance between the electrodes of the instrument test box is not less than 1012Ω.
