Timely handling of malfunctions in the Edm electronic balance is the key to ensuring data reliability
Date: 2025-11-17Read: 0
Edm electronic scales are widely used in the fields of pharmaceuticals, chemistry, materials, and quality inspection. It is sensitive to the environment, operation, and maintenance, and even a slight carelessness can lead to problems such as weighing drift, poor repeatability, abnormal display, or calibration failure. Scientific identification and timely handling of malfunctions in the Edm electronic balance are key to ensuring data reliability and equipment lifespan.
Problem 1: Unstable or continuously drifting weighing results
Reason: Airflow disturbance, temperature fluctuations, electrostatic interference, or insufficient preheating.
Countermeasure:
Ensure that the balance is placed on a shock-absorbing platform, close the windproof cover door, and stay away from the air conditioning vents and doors and windows;
Preheat the sensor for at least 30 minutes (1-2 hours for high-precision models) to ensure temperature balance;
For samples that are prone to static electricity (such as plastics and powders), use an ion fan to neutralize the charge;
Avoid direct contact with the weighing container and use tweezers or gloves for operation.
Problem 2: Poor repeatability (large deviation in weighing the same sample multiple times)
Reason: contamination of the scale pan, calibration failure, unadjusted level, or sample moisture absorption/volatilization.
Countermeasure:
Clean the scale pan and base, wipe them with a lint free cloth dipped in a small amount of ethanol, dry them, and then use them again;
Re execute internal or external calibration (using standard weights), especially after changes in environmental temperature and humidity;
Adjust the bottom of the balance horizontally to the center, ensuring even force distribution on all four feet;
For hygroscopic samples, use capped weighing bottles and shorten the opening time.
Question 3: Display error codes (such as "Err", "OL", "CAL")
Common code analysis:
OL "(Overload): If overloaded, remove the item immediately and do not forcefully weigh it;
Err "or" Stable "does not light up: sensor malfunction or internal component abnormality, if restarting is ineffective, contact after-sales service;
CAL flashing: Calibration needs to be performed. Follow the instructions to enter calibration mode and use the corresponding level of weight.
Question 4: Zero point cannot be reset or returns slowly
Reason: Residual foreign objects on the scale pan, magnetic shielding failure, or mechanical blockage.
Countermeasure:
Check if there are any debris stuck under the scale pan, gently lift the scale pan to clean it;
Confirm that the balance is not close to strong magnetic field equipment (such as centrifuges, motors);
Before executing the "skin removal" or "reset" function, ensure that there is no load.
