SL-030 Surface Resistance Tester Product Details
SL-030 surface resistance tester measures the anti-static ability of anti-static products by measuring the resistance of the surface of anti-static products. The instrument complies with ASTM standard D-257 test method, and passes two parallel copper electrodes at the bottom of the tester. Quickly test the resistance of the surface of the object, just place it on the surface of the object to be measured and press the red button. Ten 103-1012 LEDs on the instrument will light one of the test values, and the illuminated LED will be the measured object. Surface resistance.
1. This compact pocket-sized test meter can measure surface impedance and measure ground resistance. The range is from 103 ohms/□ to 1012 ohms/□ with an accuracy of ±1/2 range. 2. SL-030 adopts ASTM standard D-257 parallel electrode sensing method, which can easily and repeatedly measure various conductive, electrostatic discharge and insulated surfaces. Product function description How to use: To measure the surface impedance, place the watch on the surface to be tested, press and hold the red TEST button, and the continuously lit light-emitting diode (LED) indicates the magnitude of the measured surface impedance. 103 = 1 k ohm green LED 104 = 10 k ohm green LED 105 = 100 k ohm green LED 106 = 1 mega ohm yellow LED 107 = 10 mega ohm yellow LED 108 = 100 mega ohm yellow LED 109 = 1000 mega ohm yellow LED 1010 =10000 mega ohm yellow LED 1011=100000 mega ohm yellow LED 1012=1000000 mega ohm red LED 1012=insulated red LED measures ground resistance:
1. Insert the grounding wire into the grounding socket so that the right side detection electrode of the watch is insulated (on the same side as the socket), and the alligator is clamped to the ground.
2. Place the watch on the surface to be tested, press and hold the TEST button, and the LED that continuously emits indicates the magnitude of the resistance to ground. The unit of this measurement is ohms.
Calibration Period SL-030 Surface Impedance Meter Calibration Method: * The SL-030 Surface Impedance Meter should be calibrated every twelve months. * Using a decimal resistance box, connect the standard measuring resistor between the two parallel electrodes of the SL-030 meter to verify that the impedance value displayed is correct. Product technical parameters Power supply: 9 volt PP3 alkaline battery Measurement voltage: 9 volts 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 state) Measurement Degree: 10 order of magnitude transition point: 1/2 logarithm (3.16 × 10n) Transition point accuracy: ± 1/2 accuracy: ± 10% Repeatability: ± 5% Weight: 170 g Size: 130 × 70 × 25 (Millimeter Unit) Surface Impedance Table Calibration Procedure 1. The SL-030 surface resistance tester uses a 1% ultra-thin film resistor and a high-speed amplifier circuit. The calibration procedure is based on the linear circuit technology of the product. 2. The conversion point of the impedance value is 1/2 level logarithm, 3.16×10n, and the linear value of the conversion point is ±10% of the mean value per unit of measurement (mean value perunit). 3. Measuring instrument: Decimal resistance box, the resistance of the test electrode resistance box needs to be 1×103 ohm to 999×106 mega ohm or 109. When measuring more than 109 resistance, CAD technology (cadGeneraated techniques) is used because 9 volts is used. Voltage driving is difficult to verify a resistor with an impedance greater than 999 × 106. 4. Connect the two electrodes of the resistance box to the two parallel electrodes of the SV-2080, adjust the resistance to 1K position, the light-emitting diode (LED) of the table should be bright, the calibration of other files and so on, measure the impedance conversion At the point, press the switch while continuously adjusting the impedance value of the impedance bridge, and observe the impedance value when the next LED is always on (the value at this time is the converted impedance value).
SL-039A wristband online monitor mainly monitors whether the wristband is worn, too loose or disconnected instrument will alarm, thus ensuring the reliability of the human body's static electricity released to the earth through the wrist strap. It can be used by two stations (staff) at the same time. Size: 130X70X25mm Weight: 0.1kg Working pressure: 9V
