Send us your ZEN50 for a firmware update and recalibration performed to traceable national standards.
Please select if you require a Certificate of Calibration or not, either way the calibration process is the same. The certificate includes results of a manual calibration verification.
If you are sending your unit to us from outside the UK, it is vital that the package is clearly marked with:
"Inward processing relief - Item returning to factory."
Our address is:
