Troubleshooting: Disintegration Tester Display Not Activating

If you’ve encountered a situation where your disintegration tester’s display fails to activate after plugging in the device, you’re not alone. Many users initially mistake this for a technical malfunction, but there’s a key safety design behind it—let’s break down the cause and solution.

Why Isn’t the Display Activating?

This is not a defect—it’s a built-in safety feature to protect both the operator and the equipment. The disintegration tester is equipped with a water level sensor that restricts power to the display (and the device itself) until the test cups are filled with water to the specified level.

This design serves three critical purposes:

Prevents the heating element from burning out due to dry operation
Ensures consistent, accurate testing conditions (per pharmaceutical industry standards)
Safeguards laboratory staff from potential hazards associated with improper startup

Step-by-Step Fix to Activate the Display

Confirm the device is plugged into a grounded power outlet (check for secure connections).
Open the transparent cover of the water bath.
Fill the bath with purified water to the recommended level (The water level line indicates the water level is not in use; placing a beaker in the water level will raise the water level. There is a warning sign on the water tank.refer to your user manual for exact markings).
Once the sensor detects the correct water level, the display will automatically light up—your device is now ready for parameter setting and operation.

Key Technical Specifications (For Reference)

As a pharmaceutical testing instrument for tablets and capsules, here are the core specs of the disintegration tester:

Beaker Capacity: 1000ml
Speed Range: 30~32rpm
Basket Lifting Height: 55±1mm
Minimum Spacing: 25±2mm
Mesh Size: Standard 2mm
Temperature Range: RT-50℃ (Precision: ±0.3℃)
Timing Range: 1~900min (Precision: ±0.5min)
Continuous Working Time: >24h
Power Consumption: 600W
Power Supply: AC220V/110V±10%, 50/60Hz

Preventative Tips for Future Use

Always fill the water bath before powering on the device.
Regularly clean the water level sensor to remove mineral buildup or debris (avoids false detection).
Train laboratory staff on the startup sequence (follow the user manual closely).
Check water levels periodically during long-term testing to maintain optimal performance.

If the display still doesn’t activate after following these steps, contact our technical support team for further assistance—we’re here to ensure your testing process runs smoothly.
