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.
The fieldSENSE Occupational is designed specifically for the mobile industry. It’s a cost effective solution ideal for all personnel working in the vicinity of transmitting cellular antennas.
The fieldSENSE Public is designed to protect non-RF workers from accidental RF overexposure. Property owners hosting BTS sites can now ensure that contractors like window washers, painters, and maintenance staff remain in a safe RF environment.
The fieldSENSE is certified to IEC 61000-6-4, IEC 6100-6-2, and IEC 60950-1. It measures in accordance with ICNIRP (1998), FCC (NCRP), OET65 (1997), Canada Safety Code 6 (2009), and IEEE C95.1 (2005). The fieldSENSE is calibration Certified by ACRBR.
