What Is Calibration & Why It Matters

Calibration is the process of checking and adjusting a blood pressure monitor to ensure it provides accurate, reliable readings. Over time, even the most trusted monitors can produce inaccurate results due to regular wear or environmental factors.

Accurate blood pressure readings are vital for diagnosing and managing health conditions. All Rossmax devices are calibrated before leaving the Rossmax factory and therefore do not require calibration before use.

How often should you calibrate your BP monitor?

Rossmax Blood Pressure monitors are designed to be used for many years. The need for calibration will vary depending on the frequency of use of the device.

For example, a bp monitor which is used 3 times a day will not require calibration for at least 2 years from the date of first use. Devices used by medical professionals will typically have a higher frequency of use and therefore need to be calibrated more frequently.

The recommendation is annual calibration for such devices. Taga Medical, as a proud distributor of the Rossmax brand, can assist with a certificate once the device is calibrated.

Signs Your Device May Need Calibration:

  • ‘CA’ message displays on the blood pressure monitor screen
  • Inconsistent readings

Which devices can be calibrated?

Rossmax automatic and manual (aneroid) blood pressure monitors can be calibrated. Other Rossmax devices such as scales, thermometers and pulse oximeters cannot be calibrated.
