Getting Started

Sensitivity Adjustment

Full Liquid Calibration

1. Refer to Figure 1. Ensure the liquid level in the container is level with the center of the sensor.

2. Refer to Figure 2. Press the button or connect the MARK wire to the GND wire and hold for approximately 1 second, then release. The sensor's indicator light will flash rapidly (frequency 100Hz). The flashing will stop when calibration is complete, and the indicator light will illuminate (the sensor's switching point will be set below the actual detection value).

Empty Liquid Calibration

1. Refer to Figure 3. Place the sensor above the container.

2. Refer to Figure 2. Press the button or connect the MARK wire to the GND wire and hold for 5-6 seconds, then release. The sensor's indicator light will flash slowly (frequency 50Hz). The flashing will stop when calibration is complete, and the indicator light will turn off (the sensor's switching point will be set above the actual detection value).

Notes:
In most applications, full liquid calibration meets most detection requirements, especially in critical applications with significant changes in media type and temperature. Calibration with the liquid level approximately covering 50% of the sensor surface is advantageous. Empty liquid calibration is advantageous when there is a large amount of residual film, moisture, foam buildup in the container, or when the container wall thickness is greater than 15mm. It allows for empty liquid calibration even with accumulated material.

Sensor (or probe) contact surface and container outer wall gap requirements

The sensor (or probe) contact surface should ideally be firmly bonded to the container outer wall using AB or other Anaigu adhesives. If there are special requirements, the gap should be less than 0.5mm, or ideally, there should be no gap; otherwise, measurement accuracy may be affected

Installation Method

1. Screw Fixing Installation Method
   

2. Adhesive Installation Method
   The adhesive installation method is shown in the picture. The blank side can be directly adhered to the outer wall of the plastic container. Adhesive materials can include silicone sealant, 704 silicone, and waterproof 3M double-sided tape.

Precautions:

1. Do not use double-sided tape made of foam.
2. The container material must be insulating.
3. Use a material that is uniform in texture, free of air pockets, air bubbles, and does not absorb water, and whose dielectric constant does not easily change.
