still be saved; however, readings may be inaccurate (> ±10 %).
The sensor has FAILED the response/reliability test; the sensor requires urgent
replacement before being deployed. Span value WILL NOT be saved; return to
the service centre for repair.
If N/A appears on the LCD, there may be a sensor/hardware issue causing
readings to fail. If the error persists, return for service. (ERROR 3 may also
indicate this issue).
