Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

Use AS505 as a transmission fluid transmittance and temperature tester. Clean the probe, check the vehicle condition, and read the result indicators carefully before judging whether transmission fluid service may be needed.<\/p>\n <\/div>\n

\n
\n

Transmission Fluid Testing<\/h3>\n

AS505 is mainly used to test automotive transmission fluid transmittance and oil temperature. Reduced transmittance may be related to impurities, deposits, or metal contamination in the fluid.<\/p>\n <\/article>\n

\n

Suggested Test Interval<\/h3>\n

It is recommended to check transmission fluid condition every 5,000-10,000 km, especially before deciding whether transmission fluid service is needed.<\/p>\n <\/article>\n

\n

Clean The Probe First<\/h3>\n

Wipe the test probe clean before each measurement. Residual oil, dirt, or contamination on the probe may affect the reading.<\/p>\n <\/article>\n

\n

Engine Below 60\u00b0C<\/h3>\n

Before testing, make sure the engine temperature is below 60\u00b0C. This helps keep the measurement process within the recommended operating condition.<\/p>\n <\/article>\n

\n

6V Battery Power<\/h3>\n

The tester uses 4 \u00d7 1.5V AAA batteries for a 6V operating voltage. Install batteries with the correct polarity before powering on.<\/p>\n <\/article>\n

\n

Auto Power-Off<\/h3>\n

The tester automatically powers off after about 5 minutes of no activity. Long press the power key to turn the tester on or off manually.<\/p>\n <\/article>\n <\/div>\n
