Fluid Fit, Method and Result Questions
Which brake fluids can AS501 test?
Select the matching mode for DOT 3, DOT 4, DOT 5, DOT 5.1, ENV 4 or ENV 6 before placing the clean probe in the fluid.
Bir sınav ne kadar sürer?
The manufacturer’s procedure states that the result appears after about 10 seconds.
Does the reading replace a boiling-point test?
No. AS501 screens moisture/grade through its supported method; follow the vehicle or fluid maker’s service procedure when a boiling-point test or another confirmation is required.
How should the probe be handled between tests?
Clean the probe after each sample and avoid transferring residue between different fluid types.
