On the T24 HR setting the List Size to 6 allows the operator a fast responding Next key that cycles through the closest 6 modules to allow the operator to note any out of limit readings The operator checks the Data Tag displayed on the handheld as the Next key is pressed against the Data Tag painted on the modules affixed to the bridge The operator walks the length of the bridge and stops approximately every 6 meters and quickly scrolls through the small list size and records the readings of the 6 local modules The list dynamically repopulates as he walks along the length of the bridge During the walk modules are automatically woken by the handheld as they enter range and as the operator walks out of range the modules automatically return to sleep Scenario 2 The operator has 3 rooms to monitor Each room contains 10 acquisition modules These modules are always fully awake but operate at a transmission interval of 10 seconds There is another device that is logging the data from these modules so their sleep delay is set to zero to disable that function By setting the List Size to 10 the operator can enter the desired room and simply cycle through the 10 modules present in that room Because the acquisition modules only transmit at 10 second intervals it can take up to 10 seconds for a particular module to be available from the handheld The timeout on the handheld is set to 31 seconds The input to the acquisition modules is very slow to c
