Data Synch
: (RX Only) Initiates data synchronization between the TX and RX, if they are in communication
range of each other
(less than 50’ and free of obstructions between) and should remain close while the
transfer takes place). Once the transfer is completed, both displays will automatically return to the Startup
screen. The time required for data synchronization depends on the number of measurements conducted
since the last synchronization. We recommend Data Synch to be conducted at least once every 10
measurements. Synchronization allows measurements to be validated. Table 2 lists the possible outcomes
for the measurement validation process and the measurement condition which causes the outcome.
