Description: 1.This small pocket detection table can measure the surface impedance, and measurement of ground resistance, wide range, from 103 ohm/ to 1012 ohm/, accuracy of + 1/2 range. 2.030 adopts ASTM standard D-257 parallel electrode sensor method, can simply, repeatedly measure all kinds of transmitting, electrostatic discharge, insulating surface.
Technical parameter: Power:: 9V PP3 alkaline battery Test voltage:: 9V Temperature range:working temperature 5℃--49℃ Storage temperature:-15℃--60 ℃ Relative humidity: 0%--90% (not state of condensation) Measuring degrees: in the order magnitudes of ten Change point:1/2 Logarithmic degree (3.16* 10 n) Transition point accuracy: + 1/2 degree Accuracy: + 10 % Repeatability: + 5% Weight: 170g Dimensions: 130 * 70 * 25 (mm)
HOW TO USE: To measure the surface impedance, place the meter on the surface to be measured and hold down the red Test button. The continuously illuminated LED indicates the magnitude of the measured surface impedance.
103=1千Ohm green LED 104=10千Ohm green LED 105=100千Ohm green LED 106=1兆Ohm yellow LED 107=10兆Ohm yellow LED 108=100兆Ohm yellow LED 109=1000兆Ohm yellow LED 1010=10000兆Ohm yellow LED 1011=100000兆Ohm yellow LED 1012=1000000兆Ohm red LED 1012=insulation red LED
Measurement of resistance to earth:
1. Insert the Ground wire into the Ground socket, so as to insulate the detection electrode on the right side of the meter (on the same side with the socket). Clamp the alligator to your floor. 2. Place the meter on the surface to be measured, hold down the Test button, and the continuously glowing LED indicates the magnitude of the resistance value to the ground. The unit of measurement is ohms.
Calibration period SL-030 surface impedance meter calibration method: * Calibrate the SL-030 surface impedance meter every 12 months * Using a decade resistance box, connect the standard measurement resistor between two parallel electrodes of the SL-030 meter to verify that the displayed impedance value is correct.
Calibration procedure of surface impedance meter: 1, SL-030 surface resistance tester uses 1% ultra-thin film resistance and high-speed amplifier circuit, its calibration steps are based on the linear circuit technology of the product. 2. The conversion point of impedance value is 1/2 logarithm, that is, 3.16× 10N, and the linear value of the conversion point is ± 10% of the mean value perunit of each measurement gear. 3. Measuring instrument: Decade resistance box. The resistance of the test electrode resistance box should be 1×103 to 999×106 megohm or 109. CADGENERAATED techniques are used when the resistance value is greater than 109. 4, connect the resistance box of two electrodes to SV - 2080 on two parallel electrodes, dispatch resistance to 1 k, the table of 103 light-emitting diodes (leds) should be bright, other archives of calibration and so on, measure the impedance transformation point, press the switch and continuously adjust the impedance values of impedance bridge, and observation was made in a LED lights when normally on the impedance value (when the value for the transformation of impedance values).
