continually, so there may be slight differences between your
purchase equipment and its instruction manual. You can find the
changes in the appendix. Sorry for the inconvenience. If you have
further questions, welcome to contact with our service department.
The input/output terminals and the test column may bring voltage,
when you plug/draw the test wire or power outlet, they will cause
electric spark. PLEASE CAUTION RISK OF ELECTRICAL SHOCK!

Page 6: Overview
I. Overview Automatic interfacial tension tester, in accordance with GB6541-86 "Petroleum products oil to water interfacial tension measurement method" (circle method) standard requirements, measure the surface tension of various liquids (liquid-gas interface) and the interface between mineral oil and water Tension (liquid-liquid interface). -
Page 7: Working Principle
III. working principle The working principle of the instrument is to apply the high-frequency induction micro-displacement automatic balance measurement system to the torsion balance, that is, when the force acting on the platinum ring changes, the balance bar connected with the platinum ring is in the two eddy current probes Displacement occurs in the two eddy current probes, causing the differential transformer to lose balance, and the input signal of the differential amplifier in the circuit also loses balance. -
Page 8: Installation And Level Adjustment
Figure 1 V. installation and level adjustment Place the host on a stable platform with no wind flow, as shown in Figure 2, unscrew the two fixing screws on the back of the instrument, remove the upper top plate, and install the control magnet, ring frame rod, and platinum as shown in Figure 3. -
Page 9: Instrument Operation
Figure 3 Instrument Operation After turning on the power, turn on the power switch. The instrument enters the following startup interface. Press any key or automatically switch to the main menu page after 5 seconds. - Page 10 Sample test: enter the sample test interface to perform sample test. Pure water calibration: enter the pure water calibration interface and perform a pure water calibration test. Parameter setting: Enter the parameter setting interface to set related parameters. Historical record: Enter the historical record interface to view historical data. Weight calibration: Enter the weight calibration interface.
