Surface resistance tester ACL-380

Surface resistance tester (USA) Model: ACL-380 Instrument: This compact mini detection table can measure the surface impedance, and can measure ground resistance, wide measuring range from 103 ohms / □ to 1012 ohms / □ accuracy of ± 1/2 range. acl-380 uses astm standard d-257 parallel electrodes sensing method, it can easily and repeatedly measuring a variety of conduction, electrostatic discharge type, insulation type surface. Use: To measure the surface impedance, measured on the surface of the table, hold down the red measurement (test) button for shining a light emitting diode (led) the indication of the magnitude of the surface impedance measurements. 103 = 1 Kohm Green led 104 = 10 kilohms Green led 105 = 100 kilohms Green led 106 = 1 megohm yellow led 107 = 10 megohms yellow led 108 = 100 megohms yellow led 109 = 1000 megohms yellow led 1010 = 10000 megohm yellow led 1011 = 100000 megohms yellow led 1012 = 1000000 megohm red led> 1012 = red led measuring insulation resistance of the ground wire to ground into a grounded (ground) socket, so that the right side of the detection electrode insulation sheets ( and outlet on the same side). The alligator clip connected to your ground. The table on the test surface, hold down the measurement (test) button, and continue to light the led indicate the magnitude of the resistance on the ground. This measurement value in ohms. Parameters: Power supply: 9 volt alkaline battery pp3 measuring voltage: 9 V Temperature range: Operating temperature 5 degrees C to 49 degrees C Storage Temperature: -15 degrees Celsius to 60 degrees Celsius Relative Humidity: 0% to 90% (non-condensing) Measurement of : magnitude transition point 10: 1/2 level logarithmic (3.16 × 10n) transition point accuracy: ± 1/2 Accuracy: ± 10% Repeatability: ± 5% Weight: 170 g Dimensions: 130 × 70 × 25 ( millimeters) acl-380 surface impedance meter calibration method calibration cycle: to be calibrated every twelve months acl-380 surface impedance meter. Using decimal resistance box, the standard measurement resistor across between two parallel electrodes acl-385 meter to test its display of impedance values ??are correct. acl-380 surface impedance meter calibration step acl-380 used in the table is 1% ultra thin film resistors and high-speed amplification circuit calibration procedure is based on the product of linear technology carried out. Conversion point impedance value is 1/2 level on which number 3.16 × 10n, linear conversion value of each point in the value of the gear (meanvalueperunit) measurement ± 10%. Measuring equipment: decade resistance box, resistance box test electrode resistance requires 1 × 103 999 × 106 mega ohms to 109 ohms or using cad technology (cadgeneratedtechniques) when measured resistance is greater than 109, since it is a 9-volt drive difficult to verify the impedance value is greater than 999 × 106 resistive. The two electrodes are connected to the resistance box acl-380 two parallel electrodes, the resistance 1k transferred position table 103 light-emitting diodes (led) should be bright, calibration, and so on other stalls, measuring impedance conversion point Press the switch, while continuously adjusting the impedance value of the impedance bridge, and observe the resistance value (in this case the value of the conversion impedance values) file led lights lit next time.
