Keep the probe clean and use the displayed data together for a more reliable judgment.Use And Maintenance NotesAS507 is designed for power steering fluid testing.Do not mix-test different fluids without cleaning the probe.Clean the probe before and after each test.Use the displayed transmittance, OK / Warning / Replace status, and temperature together when judging fluid condition.The tester uses 4 AAA batteries; replace batteries when the battery level is low.Store the probe clean and dry after use.Questions And AnswersThese answers cover what AS507 tests, how results are judged, oil temperature display, probe design, battery requirements, operation, compatible fluid type, AS series differences, and warranty support.What Does AUTOOL AS507 Test? AS507 tests power steering fluid condition by evaluating transmittance and impurity level. It is designed to help users judge whether power steering fluid is in good condition, needs attention, or should be replaced.How Does AS507 Judge The Fluid Condition? AS507 uses a high-precision optical probe and big data algorithm analysis to evaluate fluid transmittance and impurity level. The screen shows transmittance, temperature, and status guidance such as OK, warning, or suggested replacement.Can AS507 Display Oil Temperature? Yes. AS507 includes a temperature sensor and can display temperature in °C or °F. The temperature measurement range is 0-85°C / 0-185°F.How Long Is The Probe? The flexible probe is 350mm long. The test cable length is 80cm, and the hose uses Teflon / PTFE material for oil resistance, oxidation resistance, and corrosion resistance.What Batteries Does AS507 Use? AS507 uses 4 AAA batteries and operates at 6V. Replace the batteries when the battery level is low.How Do I Use AS507?
