ST030B
Product Overview
ST-30B surface resistance tester follows ESD standard test method.
Ten 103 -1012 Ohms/sg LED on the instrument light up one of the test values just by placing it on the surface of
the object to be measured and pressing the red button.
During the test, the surface conductivity, surface electrostatic dissipation and surface insulation of the object can
be quickly tested through the two electrodes of the tester.
Product Features
1. The test voltage in the machine is automatically switched between DC10 volts and DC100 volts, which
improves the accuracy of the test results.
2. With high measurement accuracy, simple operation and convenient carrying, it is an ideal choice for measuring
surface resistivity.
3. With battery voltage under-voltage indication function. When the battery voltage is lower than 6.8 volts, the
battery indicator lights up.
4. Using the temperature and humidity module which works independently, it shows the current
temperature and humidity. The module consumes very little power and the battery of the module can last for about
one year.

Use the Method
Press the TOUCH button, and the red lights corresponding to "℃", "RH%", "LOW" and "INSULATIVE" will
light up. After pressing the TOUCH button for a few seconds, the instrument measures the surface resistance value
of the object, and one of the ten 103-1012 Ohms/sq LEDs of the instrument lights up, and the LED lamp indicates
the surface resistance value of the current object. Measure surface resistance: As shown below
