How To Use

How To Use

AS507 is designed for quick power steering fluid checks. Clean the probe, insert it into the fluid, start the test, and read transmittance, temperature, and condition status on the screen.

Wipe The Probe

Clean the test probe before measurement to avoid contamination from dust, previous test fluid, or residue.

Submerge The Probe

Insert the testing probe into the power steering fluid and make sure the probe is properly submerged.

Start The Test

Press the test button to start measurement. The tester analyzes fluid condition through optical detection.

Read The Result

The interface displays transmittance, temperature, and condition status such as OK, warning, or suggested replacement.
