Sensor Lock
The SENSOR LOCK function locks each sensor individually and prohibits the user from
switching sensors on the locked channels. This may be password-protected. The sensor
lock is set to ON or OFF. After selecting ON, a screen is displayed showing the sensor
channel number, serial number, and the message ‘NOW LOCKED’. When the sensor
lock is ON, the thermo-hygrometer measures only on that channel using the sensor that
was attached when sensor lock was set ON. This can be used to prevent inadvertent
attachment of an uncalibrated sensor or one that is not in the desired location. It uses the
sensor serial number to identify the sensor. To exchange a different sensor, the sensor
lock must be set to OFF.
