Zero/Cal Lockout

The Zero/Cal Lockout facility provides a mean of ensuring that a measurement
cannot be taken until the connected sensor has been zeroed and calibrated. If the
Zero/Cal Lockout facility is enabled and a sensor is connected which have not
been zeroed and calibrated, then the display window for the sensor will display
the message Please Zero and Cal.
