Surface Resistance Tester A detailed description of
Product Model: CS6683583
Product Name: Surface Resistance Tester
Product Information: 1,ACL380 this king of mini tester not only can test the surface impedance but also can test the ground resistance, the scaling range is wide, from 103Ω to 1012Ω, and the precision is ±1/2.
2,ACL380 surface resistance tester adopts the ASTM standard D-257 parallel electrode sensor method, which is convenient to test the conductive type, electron-static charge type and insulating type surface.
3.Usage: Put the tester on the surface of the object to test the surface resistance of the object, then press the red button of TEST ,the continuous shining LED will display the surface impedance level; The way test the grounding resistance: Plug the ground wire to the ground socket, by this way can insulate the test electrode of tester’s right part (the same side of the socket, then connect the alligator clip to the ground wire and put the test on the surface of the object, press the button of TEST, the the continuous shining LED will display the surface impedance level, the unit of the measured value is ohm.
Product Parameters:Power Supply: 9V PP3 alkaline battery; Measuring Voltage: Rated 9V; RH: 0％~90％(non-condensing); Precision:±10％; Repetitive Error: ±5％; Weight: 170g(60Z); Size: 127×76×26mm.
calibration method of the ACL-380 Surface Method: Calibration Interval: The calibration interval of the ACL-380 tester is annual, it adopts the decade resistance box, connect across the standard measuring voltage between the two parallel electrodes to test the impedance value. Parameters: Measuring Voltage:9V, temperature range: working humidity 5 ℃ to 49 ℃; Storage Temperature: -15 ℃ to 60℃; RH: 0％ to 90％(non-condensing state); Measuring Degree：10 orders of magnitudes; Transition point: 1/2 level logarithm; Precision of the transition point: ±1/2 level; Precision: ±10％; Repeatability: ±5％.
ACL-380 surface resistance tester calibration steps: The ACL-380 tester adopts 1% ultra-thin membrane resistance and high-speed amplifying circuit, the calibration of the calibration steps is based on the product’s linear technology. The linear value of the transition point is the ±10％ of the mid-value(mean value per unit) of each measurement file.
Measurement Instrument: Decade resistance box, the resistance of the test electrode resistance box requires voltage from 1×103 to 999×106Ω or 109Ω, when the resistance value is more than 109Ω, then it adopts the CAD technology (cad Generated techniques), for that 9V voltage drive is difficult to test the resistance value which is more than 999×106Ω. Connect the resistance box two electrodes between the two parallel electrodes, change the resistance in the IK position, the 103 LED tester will light, the other files of calibration is in the way. When testing the impedance transition point, press the switch and continuously adjust the impedance value of the impedance bridge, and observe the next file impedance value when the LED light brights out(This value is the transition impedance value).
