Principle and characteristics of surface resistance tester with heavy weight

The heavy weight surface resistance tester is a compact, lightweight, low energy consumption electrostatic resistance tester, which can measure the surface resistance, surface resistivity, volume resistance, ground resistance of objects. The heavy weight surface resistance tester has high measuring accuracy, fast speed and easy to use. It is especially suitable for use in laboratories and automatic detection lines with high requirements. The new line break alarm function, that is, the open circuit alarm, can know whether the instrument is working in the normal test state. The new alarm function is open circuit alarm. Test, the test range is wide, the application field is not limited.

The heavy weight surface resistance tester measures the resistance of the surface of the antistatic product to detect the antistatic ability of the product. Before measuring, ensure that the surface to be measured is clean and pollution-free. Ionic wind bar

Surface resistance: (SurfaceResistivity)

1. Parallel Probe ResistivityMethod (Parallel Probe ResistivityMethod)

The parallel probe impedance measurement method is a measurement method according to the EOS/ESD-S11.11-1993 standard, which is a fast method to measure the resistance value of planar uniform materials. This method is also suitable for the measurement of multilayer materials, but the temperature and humidity conditions at the time of measurement must be indicated in the impedance value report.

A. Place the table on the surface of the object to be measured.

B, switch to the desired voltage position (10 volts or 100 volts)

C, at about 5 pounds of pressure to continuously press the measurement button, at this time the LCD screen will display the measured surface impedance, temperature and relative humidity values, the whole measurement process is about 15 seconds. · Surface impedance in ohms /□ · Temperature in photography · Relative humidity in percentage In each measurement, after the measurement button is pressed, the ACL-800 meter will continuously display the dressing measurement value, and the last measurement value will be displayed for approximately 45 seconds after the button is released.

2, Concentric Ring Probe Resistivitymethod (Concentric Ring Probe Resistivitymethod is optional) Insert the connection plug into the two 3.5 mm jacks of the meter and connect the banana plug to the concentric ring probe (optional). After placing the probe on the surface of the object to be tested and pressing the button for about 15 seconds, the correct temperature and relative humidity will be displayed on the LCD screen, and the correct surface impedance value is the reading on the LCD screen multiplied by 10, in ohms /□. For example, the display on the crystal screen is 3.5× 104 ohms /□; The actual impedance is 3.5× 105 ohms /□.

Surface ResistanceMeasurement (point-to-point) (Surface Resistance Easurement (RTT))

This measurement method is in accordance with the EOS/ESD-S4.1 measurement requirements to measure the resistance between two points independent of ground. The measurement results obtained by this measurement method are related to the handling of the object to be measured, the distance between the two 5-pound probes, etc. Therefore, the correct measurement procedure should be selected and the test should be carried out under the same required measurement conditions every time.

A. Insert the connection plug into the two 3.5mm jacks of the meter and connect the banana plug to the two 5-pound weight probes.

B. Place the two probes on the surface of the object to be measured according to the measurement procedures.

C, weight type surface resistance tester select the required voltage value (10 volts or 100 volts)

D, press the switch until the selected voltage value is displayed (10 volts or 100 volts), continue to press the switch until the measured resistance (in ohms), relative humidity and temperature are displayed on the LCD screen.

(Surface-To-Ground Resistance Measurement(RTG)) (Surface-to-ground Resistance Measurement(RTG))

This measurement method is used to measure the surface resistance between a point on the surface of an object and another ground point on the surface, and the measurement method conforms to the EOS/ESDS4.1 measurement standard.

A. Insert one end of the two wires into each of the two 3.5 mm jacks of the watch, then connect one to the alligator clip and the other to A 5-pound disk probe.

B. Connect the crocodile clip to the known ground point, and place the disc-shaped probe on the surface of the object to be measured according to the measurement requirements.

C, heavy weight surface resistance tester press the measurement button until the resistance (unit is ohm), relative humidity, temperature values are displayed on the display screen, the measurement results meet EIA, EOS/ESD, ANSI, IEC-93,CECC,ASTM measurement standards, for the measurement of high impedance materials to ensure the measurement of high precision measurement results. Be careful not to overlap the two leads, and do not touch the probe, the lead and the measured object with your hand.
