LFY-406S Yarn Conductivity (Resistance) Tester

Main purpose 
This instrument can be used to measure the unit resistance of yarns made by blending or compounding conductive fibers with other fibers. The yarns are connected as parallel resistors of equal resistance value, and the resistance value of the parallel resistors is measured to calculate the unit resistance of the yarn, which is used to represent the conductive performance of the yarn. 
Main technical indicators

It adopts a highly integrated 3 1/2-digit digital display. 
2. Measuring range: 1×10³Ω ～ 9.999×10¹⁴Ω 
3. The internal test voltage can be switched between DC 50V and DC 100V. 
4. Timer: 0.01 to 99.99 seconds or adjustable in minutes and hours settings; 
5. Working environment temperature: (20 ± 5) °C, humidity: (35 ± 5)% RH 
6. When the instrument is operating under a stable voltage and without any signal input, the zero point drift should be less than ±5% within a period of 1 to 8 hours. 
7. Basic error of the instrument in measuring the standard resistor: (1×10³Ω ～ 1×10¹¹) ≤ ±5%; greater than 1×10¹¹ ≤ ±10%; 
8. Sample for testing: (250 ± 1) mm × (220 ± 1) mm × (2 ± 1) mm 
9. The width of the clamping plate of the sample holder should be no less than 30mm, and the length should be greater than 220mm. 
10. Includes a shielding box, test sample board, test sample holder, electrode wires, and standard resistance box.
