Introduction to the use of heavy hammer surface resistance tester
What is a heavy hammer surface resistance tester? The heavy hammer surface resistance tester is an electrostatic resistance tester with low energy consumption, which can measure the surface resistance, surface resistivity, volume resistance, and ground resistance of objects. Its measurement accuracy is high, speed is fast, and it is easy to use. It is especially suitable for demanding laboratories and automatic detection lines. Next, Runfengyuan will give a specific introduction on the use of the weight-type surface resistance tester.
The weight-type surface resistance tester measures the surface resistance of the anti-static product to detect the anti-static ability of the anti-static product. First, make sure that the surface to be tested is clean and pollution-free before the measurement.
How to use the hammer type surface resistance tester:
1. Surface impedance measurement:
The parallel probe impedance measurement method is a measurement method that conforms to the EOS/ESD-S11.11-1993 standard. It is a fast method for measuring the resistance of a flat uniform material. This method is also suitable for the measurement of multilayer materials, but the temperature and humidity conditions during the measurement must be noted in the impedance report.
1. Place the watch on the surface of the object to be measured.
2. Turn the switch to the desired voltage position (10V or 100V)
3. Continue to press the measurement button with a pressure of about 5 pounds. At this time, the LCD screen will display the measured surface impedance, temperature and relative humidity. The entire measurement process takes about fifteen seconds.
·The unit of surface impedance is ohm/□
·Temperature unit is per shot
·The relative humidity unit is percentage
In each measurement, after pressing the measurement button, the ACL-800 meter will continuously display the trimming measurement value, and within about forty-five seconds after releasing the button, the last measurement value is displayed.
4. Concentric ring probe impedance measurement method
Insert the connecting plug into the two 3.5 mm jacks of the meter, and connect the banana plug with 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 weighted surface resistance tester will display the correct temperature and relative humidity on the LCD screen, and the correct surface impedance value will be displayed on the LCD screen. The reading above is multiplied by 10, and the unit is ohm/□. For example: the display on the crystal screen is 3.5×10 4 ohm/□; the actual impedance value is 3.5×10 5 ohm/□.
2. Surface resistance measurement
This measurement method is in accordance with the EOS/ESD-S4.1 measurement requirements to measure the resistance between two points independent of the ground. The measurement results obtained by this measurement method and the processing of the measured object, between two 5-pound probes The distance and other factors are related, therefore, the correct measurement procedure should be selected, and the test should be performed under the same required measurement conditions each time.
1. Insert the connecting plug into the two 3.5 mm jacks of the meter, and connect the banana plug with the two 5-pound probes.
2. Place the two probes on the surface of the object to be measured in accordance with the measurement procedure.
3. Select the required voltage value (10 volts or 100 volts) for the weight surface resistance tester
4. Press the switch until the selected voltage value (10V or 100V) is displayed, continue to press the switch until the measured resistance (in ohms), the relative humidity and temperature are displayed on the LCD screen.
3. Surface-to-ground resistance measurement
This measurement method is used to measure the surface resistance between a point on the surface of the object and another grounding point on the surface. The measurement method conforms to the EOS/ESDS4.1 measurement standard.
1. Insert one end of the two wires into the two 3.5mm jacks of the watch, and then connect one of them to the alligator clip, and the other to a 5-pound disc probe.
2. Connect the alligator clip to the known grounding point, and place the disc probe on the surface of the object to be measured according to the measurement requirements.
3. Press the measuring button of the heavy hammer surface resistance tester until the resistance (in ohms), relative humidity, and temperature are displayed on the display. The measurement results conform to EIA, EOS/ESD, ANSI, IEC-93, CECC, ASTM Measurement standards. To ensure high-precision measurement results when measuring high-impedance materials, care must be taken not to overlap the two leads, and do not touch the probe, lead and the object under test with your hands.
