• Metal Hose: Flexible conduit for the probe.
• LED Illumination Lamp: Provides light for testing in dark areas.
• Display Screen: LCD screen showing measurement results and indicators.
• Function Switch Key (F): Used to switch between different brake fluid types (DOT3, DOT4, DOT5.1).
• Power Button: Turns the device on and off.
• Data Hold/Lighting Key (H/C): Toggles data hold function and LED illumination.
• Detection Head: The part of the probe that is immersed in the brake fluid for testing.

4. Setup and Battery Installation

The HT5009 requires two 1.5V AAA batteries (not included) for operation.

1. Locate the battery compartment cover on the back of the device.
2. Slide or unclip the cover to open the compartment.
3. Insert two 1.5V AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Close the battery compartment cover securely.

5. Operating Instructions

5.1 Power On/Off

• Press the Power Button to turn the device on.
• The device will automatically power off after a period of inactivity to conserve battery.

5.2 Selecting Brake Fluid Type

• After powering on, press the Function Switch Key (F) to cycle through the brake fluid types: DOT3, DOT4, and DOT5.1.
• Ensure the selected type on the display matches the brake fluid you are testing.

5.3 Performing a Test

1. Ensure the brake fluid reservoir cap is removed and the fluid level is accessible.
2. Carefully immerse the metal detection head of the probe into the brake fluid. Ensure the probe is fully submerged for accurate readings.
3. Hold the probe in the fluid for approximately 3 seconds.
4. Observe the display for the water content percentage and the color-coded backlight indication.
5. Remove the probe from the fluid and clean it thoroughly after testing.

5.4 Interpreting Results (Three-Color Backlight Indication)

The HT5009 provides clear visual feedback through its three-color backlit display and auditory alarms:

• Green Backlight (0-2% water content): Indicates that the brake fluid is in good condition and still usable.
• Yellow Backlight (2-3% water content) with Slow Beep: Indicates that the brake fluid is starting to degrade and should be considered for replacement soon.
• Red Backlight (>3% water content) with Fast Beep: Indicates an urgent need to replace the brake fluid immediately.

5.5 Data Hold and Illumination

• Press the Data Hold/Lighting Key (H/C) briefly to hold the current reading on the display. Press again to release.
• Press and hold the Data Hold/Lighting Key (H/C) to turn the LED illumination lamp on or off.

6. Maintenance

Proper maintenance ensures the longevity and accuracy of your HT5009 Brake Fluid Tester.

• Probe Cleaning: After each use, especially when testing different types of brake fluid, thoroughly clean the detection head with a clean, dry cloth. Residual fluid can affect subsequent readings.
• Storage: Store the device in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure consistent performance.
• Calibration Resistor Socket: The device includes a built-in calibration resistor socket. By inserting the probe into this socket, you can simulate different measurement environments to verify the accuracy of the detector. Refer to the specific calibration procedure if provided in a separate advanced manual or by the manufacturer.
