Calibration Frequency Recommendations
1. Routine: It is recommended to have it calibrated by a professional institution every 1-2 years.
2. Special Circumstances: If the device has experienced severe vibration or drop, or if you notice abnormal fluctuations in measurement results, or if the readings are consistently too high or too low, calibration should be performed immediately.
3. High-Frequency Users: If you need to take measurements multiple times a day (e.g., for patients with hypertension), consult your doctor about shortening the calibration cycle (e.g., every six months).
Why is calibration necessary?
1. Decreased accuracy: Wear and tear on mechanical parts can cause measurements to deviate from the true value, potentially affecting your health assessment.
2. Regulatory requirements: As a medical device, regular calibration is a necessary procedure to ensure its accuracy and compliance with safety regulations.
How to perform calibration?
1. Do not disassemble it yourself: This may completely damage the device.
2. Seek professional service: Contact the device manufacturer, authorized service center, or have it professionally calibrated at a hospital's equipment department or metrology testing institution.
