How do you properly use an electronic balance?
Feb 07, 2025|
View:530Weighing technology has been an indispensable part of scientific experiments and industrial production since ancient times. From the early mechanical balances to modern electronic balances, there has been a qualitative leap in the accuracy and convenience of weighing tools. Nowadays, electronic balances, with their high precision, rapid response, and versatility, are widely used in fields such as laboratories, pharmaceuticals, and food testing. However, many users often cause measurement errors or equipment damage due to improper operation during use. So, How do you properly use an electronic balance? This article will provide you with comprehensive guidance, covering preparation work, operation steps, maintenance, and answers to common questions.
Proper steps for the operation of the electronic balances
Conditions to be ensured before usage of electronic balance.
When preparing for new situations, testing their environment and equipment.
The Environmental Requirements: Set the balance on a flat, stable table and avoid vibration, air currents, and temperature difference. Temperature: 20-25°C, Humidity: 50%-60%
Warm-up and Calibration:After powering on equipment, leave to warm up for 15–30 minutes. Calibration is performed after the equipment stabilizes. For internal or external calibration, use standard weights (such as 100g or 200g).
Cleaning the weighing pan: Use a soft brush or alcohol swab to clean the weighing pan to prevent residues from affecting the measurement results.
Standardized Steps and Precautions: Weighing Operation
The accuracy of an electronic balance will be ensured correctly operate.
Sample Placement:Avoid impact or tilt when placing the sample in the weighing pan. Used weighing paper or containers can be used for powder or liquid samples.
Stable Reading: Wait for the value displayed on the screen to stabilize (generally 2-5 seconds) and take the final reading. Monitor for environmental interference or sample state if the value remains variable.
Tare Function:Place the container first, then press the key of "Tare", and then add the sample to weigh the net weight.
Special Functions: Maximizing the Performance of the Electronic Balance
Modern electronic balances are usually equipped with a variety of advanced functions to meet complex measurement needs:
Unit Conversion: Switch between units such as grams (g), milligrams (mg), ounces (oz), etc., as required to ensure that the data meets the experimental requirements.
Statistical Calculation: Some models support statistical functions such as average value and standard deviation, which are suitable for repetitive experiments.
Animal Weighing Mode: For live samples, enable the dynamic mode to capture the stable weight during movement.
Maintenance: The Key to Prolonging Equipment Life
To ensure the long-term and stable operation of an electronic balance, regular maintenance is unavoidable:
Daily Cleaning: After using the balance, use wet cloth to clean the weighing pan and the housing to prevent dust or corrosive substances from accumulating.
Moisture-proof and Shock-proof: Please put the balance into a dry environment, and do not place it in harsh vibration or impact.
Regular Calibration: If the usage frequency is high, increase the calibration frequency at 1 month regular calibration.
Battery Management: If the sensing device is powered by a battery, ensure that you regularly check the battery level and replace it in time, otherwise it will affect the accuracy due to insufficient power.
Common Problems and Solutions
Display not responding or flickering
Possible Reasons: Poor connection of power supply or Battey power is weak or internal circuit failureSolution: Inspect the power cord or change the battery. If the issue continues, consult an expert to evaluate the situation.
Unstable measurement results
Possible Reasons: environmental vibration or air-flow interference that stabilizes the system, or sample moisture absorption.
Solution: Weigh it elsewhere, turn the fan off, or a moistureproof container.
Calibration failure or excessive error
Possible Reasons: Damaged standard weights, uncleaned weighing pan, or equipment aging.
Solution: Weigh the weights, clean the weighing pan, or send it for repair and inspection.
Conclusion: Accurate Measurement Starts with Correct Use
How do you properly use an electronic balance? By standardizing operations, performing regular maintenance, and rationally using advanced functions, you can maximize the performance of the electronic balance and ensure that every measurement is accurate and reliable.
