Surface Resistance Tester Model: S9HW-ACL380 (ACL385 alternative) library number: M249433 


 S9HW-ACL380 surface resistance tester 

 Can measure the surface impedance can be measured on the ground resistance, wide range, from 103 ohms / □ to 1012 ohms / □, an accuracy of ± 1 / 2 range 

 S9HW-ACL380 using ASTM Standard D-257 parallel to the electrode sensing method can be simple, repeated measurements 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, continuous bright light-emitting diode (LED) that indicate the magnitude of the measured surface impedance measurement of ground resistance: the ground wire into the ground (Ground) outlet, so that the insulation of the table to the right detection electrodes (with the outlet on the same side). The alligator clip to ground line. Measured on the surface of the table, hold down the measurement (TEST) button, the LED light indicates the continued resistance to ground value of the order of magnitude. The measured values ??are in ohms. 

 S9HW-ACL380 surface impedance meter calibration period calibration method: to be calibrated every twelve months S9HW-ACL380 surface impedance table. The use of decade resistor box, the standard measure resistance across the S9HW-ACL380 table between two parallel electrodes to test its resistance value is displayed correctly. Parameters: Power supply: 9 volt PP3 alkaline battery; measuring voltage: 9 V; Temperature Range: Operating temperature 5 degrees Celsius to 49 degrees Celsius Storage temperature: -15 degrees Celsius to 60 degrees Celsius; Relative Humidity: 0% to 90% (non-condensing ); measuring degree: 10 orders of magnitude; transition point: 1 / 2 log (3.16 × 10n) transition point accuracy: ± 1 / 2 level; Accuracy: ± 10%; Repeatability: ± 5%; Weight: 170 g ; size: 130 × 70 × 25 (mm units) 

 S9HW-ACL380 surface impedance meter calibration steps: S9HW-ACL380 table uses 1% of the ultra-thin film resistors and high-speed amplifier circuit, the calibration procedure based on the product of the linear impedance circuit technology for the conversion point is 1 / 2 log that is, 3.16 × 10n, the linear conversion point is the median for each measurement file (mean value per unit) of ± 10%. Resistance requires resistance box 1 × 103 ohms to 999 × 106 trillion or 109 ohms, the resistance measurement is greater than 109 when the use of CAD technology (cad Generated techniques), as a 9-volt voltage drive hard to verify the impedance value is greater than 999 × 106 resistance. The resistance box is connected to two electrodes S9HW-ACL380 of two parallel electrodes, the resistance transferred to the 1K position, the table of 103 light-emitting diode (LED) should light, the calibration of other files and so on, measuring the impedance conversion point , press the switch while modulating the impedance of the impedance bridge, and observe the LED lights lit next file when the impedance (resistance value when the value of conversion).
