SL-030 surface resistance meter

Product details

1. This compact and pocket-sized test meter can measure surface impedance and resistance to ground. It has a wide range from 103 ohms to 1012 ohms, with an accuracy of ±1/2 range.

2, sl-030 adopts the astm standard d-257 parallel electrode sensing method, which can easily and repeatedly measure various conductive, electrostatic discharge, and insulating surfaces.

Product function description

Instructions:

To measure the surface impedance, place the meter on the surface to be measured, press and hold the red measurement (test) button, the continuously lit light-emitting diode (led) indicates the magnitude of the measured surface impedance.

Measure resistance to ground:

1. Insert the ground wire into the ground socket, so as to insulate the right side detection electrode of the meter (on the same side as the socket). Connect the alligator clip to your ground.

2. Place the meter on the surface to be measured, press and hold the test button, the continuously illuminated led indicates the magnitude of the resistance to ground. The unit of this measurement is ohms.

Calibration cycle sl-030 surface impedance meter calibration method:

*The sl-030 surface impedance meter needs to be calibrated every twelve months.

*Using a decimal resistance box, connect the standard measuring resistance across the two parallel electrodes of the sl-030 meter to check whether the displayed impedance value is correct.

Surface impedance meter calibration steps

1,030 surface resistance tester uses 1% ultra-thin film resistors and high-speed amplifier circuits, and its calibration steps are based on the linear circuit technology of the product.

2. The conversion point of the impedance value is 1/2 logarithm, which is 3.16×10n, and the linear value of the conversion point is ±10% of the mean value perunit of each measurement file.

3. Measuring instrument: Decimal resistance box, the resistance of the test electrode resistance box needs to be 1×103 ohm to 999×106 megaohm or 109. When measuring the resistance value greater than 109, cad technology (cadgeneraated techniques) is used, because 9 volts are used. Voltage drive is difficult to verify the resistance value is greater than 999 × 106 resistance.

4. Connect the two electrodes of the resistance box to the two parallel electrodes of the sv-2080, adjust the resistance to the 1k position, the 103 light-emitting diode (led) of the meter should be on, and the calibration of other gears can be deduced by analogy, and measure the impedance conversion When you click, press the switch while continuously adjusting the impedance value of the impedance bridge, and observe the impedance value when the next LED light is always on (the value at this time is the conversion impedance value).
