AUTOOL AS505 · Transmission Fluid Transmittance Tester
Inspect ATF Condition with Optical Context
Screen transmission-fluid transparency and temperature before deciding the next maintenance step. AS505 uses a flexible 800 mm probe to reach service points and shows transmittance, an analog bar, fluid temperature, and status guidance on one backlit display. The optical reading is service context rather than a stand-alone replacement decision.

서비스 워크플로
Reach, Read and Clean the Probe
Install Batteries And Power On
Open the rear battery cover, install 4 × 1.5V AAA batteries with correct polarity, then long press the power key for more than 2 seconds.
Wipe The Probe Clean
Before each measurement, wipe the probe tip clean so old oil or dirt does not affect the transmittance reading.
Check Temperature Condition
Make sure the engine temperature is below 60°C. Press the temperature key if you need to switch between °C and °F.
프로브를 물속에 잠기게 하세요
Place the testing probe into the transmission fluid. Keep the probe properly immersed during measurement.
Press Test And Read Result
Press the test button. The interface displays the transmission fluid transmittance and current fluid temperature.
Simple Sampling Procedure
Clean the probe, immerse it in the transmission fluid, then start the test and read the result.
안전한 사용
Confirm Fluid Fit Before Testing
Engine Below 60°C
Before testing, make sure the engine temperature is below 60°C. This helps keep the measurement process within the recommended operating condition.
Suggested Test Interval
It is recommended to check transmission fluid condition every 5,000-10,000 km, especially before deciding whether transmission fluid service is needed.
Clean The Probe First
Wipe the test probe clean before each measurement. Residual oil, dirt, or contamination on the probe may affect the reading.
결과를 활용하여 다음 점검 계획을 세우세요
Use the condition score to screen and compare a clean, representative transmission-fluid sample; use the specified tests when viscosity, wear metals, contaminants, or remaining service life must be assessed.

유체 적합, 방법 및 결과 관련 질문
무엇을합니까 AUTOOL AS505 테스트?
AS505 tests automotive transmission fluid transmittance and displays transmission fluid temperature. It helps users assess fluid clarity, possible contamination, deposits, and whether service attention may be needed.
Is AS505 An ATF Exchanger Or A Fluid Tester?
AS505 is a transmission fluid tester. It is used to check transmission fluid transmittance and temperature. It does not exchange, flush, drain, or refill transmission fluid.
How Often Should I Test Transmission Fluid With AS505?
It is recommended to test transmission fluid once every 5,000-10,000 km. Testing frequency can also depend on vehicle mileage, driving conditions, transmission behavior, and maintenance schedule.
How Do I Use The AS505?
Install batteries, power on the tester, wipe the probe clean, confirm the engine temperature is below 60°C, submerge the probe into transmission fluid, press the test button, and read the transmittance and temperature result on the LCD.
What Do OK, Warning, And Suggested Replacement Mean?
OK indicates transmittance is between 100% and 50%. Warning indicates transmittance is between 50% and 30%. Suggested replacement appears when transmittance is below 30%. Use these results as a service reference together with vehicle condition and workshop judgment.
Can AS505 Test Engine Oil, Brake Fluid, Or Power Steering Fluid?
AS505 is designed for automotive transmission fluid testing. For engine oil transmittance, choose AS503. For brake fluid water content, choose AS501 or AS502. For brake fluid boiling point, choose AS506. For power steering fluid transmittance, choose AS507.
What Temperature Conditions Should I Follow?
The tester operating temperature is -10°C-60°C. The transmission fluid temperature display supports 0-85°C / 0-185°F. Before measurement, the engine temperature should be below 60°C.
What Power Supply Does AS505 Use?
AS505 uses 6V power from 4 × 1.5V batteries. Open the rear battery cover, install the batteries with correct polarity, and close the cover securely before use.
What Is Included In The AS505 Package?
Package contents: AS505 main unit with built-in probe, retail box, and user manual.
Why Should The Probe Be Wiped Clean Before Testing?
The optical probe reads fluid transmittance. Oil residue, dirt, or contamination left on the probe may affect measurement feedback, so the probe should be wiped clean before each measurement.
