MEASURE MODE
When approaching a base station site, the RF technician may use the fieldSENSE in "measure" mode to ensure that he/she is not overexposed. In "Measure" mode the field strength is measured continuously. A level indicator bar provides visual feedback of the exposure levels as the instrument is moved around. The user can pinpoint sources of RF radiation and confirm that specific base station sectors have been shut down, or are transmitting reduced power levels so that can it be considered safe to approach and complete a required task.

MONITOR MODE
After confirming that relevant sectors have been powered down, the fieldSENSE can be switched to 'monitor' mode and mounted in a suitable position and orientation. The fieldSENSE continuously monitors the RF radiation levels and will alert the worker in the case of significant exposure changes. The worker is alerted by both an audio alarm and a visual alarm on the level indicator bar.

USER INTERFACE AND OPERATION
A single button toggles between user modes and power-on/off. The display and processing of measured data is limited to that which is required to make informed on-site decisions and take the necessary precautions. The device features a durable design intended for everyday use, and is compact enough to fit easily into the pocket of the user. The rubbery outer sleeve offers improved grip and protects the fieldSENSE against mechanical shock and impact. A lanyard can be used to secure the fieldSENSE around the wrist of the user and thus minimise the risk of dropping the device. A standard tripod socket at the bottom can be used to mount the fieldSENSE on a tripod when used in monitor mode.
