ATEC FieldSense FS60 5G Personal RF Monitor

fieldSENSE60 Product Information

The fieldSENSE60 is a portable device designed for measuring and logging the strength of radiofrequency (RF) fields. It is equipped with incident exposure indicator LEDs, a low battery indicator, a power on/off button, and an audio recording indicator. The device is also equipped with a fall detection and alarm system and a timer that automatically switches off the unit after eight hours to conserve battery life. The device is designed to log exposure data from all sources present within the operating frequency and exposure dynamic range and store them as the Maximum, E and H percentages with the associated date and time thereof. The fieldSENSE60 is constructed with an impact- resistant polycarbonate base layer and a heavy-duty shock-absorbing elastomer outer layer for durability. It is also equipped with scratch and scuff- resistant lens to protect the device’s display. The fieldSENSE60 can also capture voice notes which are paired with the measured data.

Usage Instructions

Prior to entering an area where transmitting antennas could be present be sure to switch your fieldSENSE60 on.

1. Switch the fieldSENSE60 on by pressing and holding the Power button for approximately 1 second.
2. The LEDs illuminate in sequence followed by a BEEP. Once on, the power indicator will flash.
3. Should the battery level be low, the low battery indicator will illuminate. Replace the batteries with AAA alkaline batteries.
4. Should the exposure level rise above 50% an audible alarm is sounded.
5. When close to or exceeding 100% of the exposure limit, the necessary precautions need to be taken.
6. Once switched on, the field strength data logger will record all field values measured every second. These are accessible via the PC application available from www.fieldsense.com.
7. Once the fieldSENSE60 is on, the fall detection & alarm system is armed and in the event of a fall being detected an alarm will sound which can only be cleared by switching the device off and on again.
8. To ensure that the device is not inadvertently left switched on causing unnecessary drain on the batteries a timer will switch the unit off after 8 hours.
9. The reported and recorded values are a percentage of the  associated exposure guideline power density, either referenced to the E or H field.
10. Data points are stored at up to once every second in a changing field. In static field conditions or below the device noise floor less points are stored to conserve memory.
11. A 6-minute average is also calculated and stored.

The fieldSENSE60 can also capture voice notes which are paired with the measured data. Once the device is on, double-tap the power button, and the Audio recording LED will illuminate.

INTRODUCTION

The fieldSENSE60 is the latest in the FieldSENSE range of Personal RF Monitors which are field proven to work as hard as you, regardless of the conditions. The extended upper frequency range of the FS60 ensures that you are warned of inadvertent RF overexposure, now also when working on mmWave SG systems. The fieldSENSE60 probe architecture is specially designed for both near-field and far-field conditions through the use of a combined E & H field probe utilizing 6 separate orthogonal probes. Now with the extended frequency range of 50 MHz up to 60 GHz. The shaped response ensures that multiple sources of concurrent radiation are individually assessed and weighed against the safe working limits and then combined giving you the total exposure in percentage of the occupational limits.

THIS DEVICE IS ONLY TO BE USED BY RF TRAINED PERSONNEL WITH A COMPLETE UNDERSTANDING OF THE RISKS INVOLVED WITH WORKING WITH RF AND KNOW THE NECESSARY PRECAUTIONS TO BE TAKEN. FURTHERMORE, ONLY USE THIS DEVICE WITHIN THE LIMITS OF THE DESIGN SPECIFICATIONS, AND ENSURE THAT IT IS NOT DAMAGED PRIOR TO USAGE.

RF MONITOR OPERATION

• Prior to entering an area where transmitting antennas could be present be sure to switch your fieldSENSE60 on.

• Switch the fieldSENSE60 on by pressing and holding the Power button for approximately 1 second.

• The LEDs illuminate in sequence followed by a BEEP. Once on, the power indicator will flash.

• Should the battery level be low, the low battery indicator will illuminate. Replace the batteries with AAA alkaline batteries.

• Should the exposure level rise above 50% an audible alarm is sounded.
  ALWAYS ADHERE TO THE RELEVANT SAFETY REGULATIONS PERTAINING TO RF EXPOSURE IN THE COUNTRY OF USE

• When close to or exceeding 100% of the exposure limit, the necessary precautions need to be taken.

• Once switched on the field strength data logger will record all field values measured every second. These are accessible via the PC application available from www.fieldsense.com.

• Once the fieldSENSE60 is on, the fall detection & alarm system is armed and in the event of a fall being detected an alarm will sound which can only be cleared by switching the device off and on again.

• To ensure that the device is not inadvertently left switched on causing unnecessary drain on the batteries a timer will switch the unit off after 8 hours.

EXPOSURE LOGGING

Once the fieldSENSE60 is switched on the cumulative exposure from all sources present within the operating frequency and exposure dynamic range are stored as the Maximum, E and H percentages with the associated date and time thereof

• It is important to synchronize your device time to your local time by plugging it into a PC running the FieldSENSE app available from www.fieldsense.com.
• The reported and recorded values are a percentage of the associated exposure guideline power density, either referenced to the E or H field.
• Data points are stored at up to once every second in a changing field. In static field conditions or below the device noise floor less points are stored to conserve memory.
• A 6-minute average is also calculated and stored.
• Accessing these values and synchronizing the date/time of the device is achieved using the FieldSENSE app available from www.fieldsense.com.

VOICE NOTES

• The fieldSENSE60 can also capture voice notes which are paired with the measured data.
• Once the device is on, double tap the power button and the Audio recording LED will illuminate.
• Speak directly into the front of the device slowly and clearly for best performance.
• A single short press of the power button will end the audio recording session, but the RF monitor remains on.
• Voice notes can be downloaded from the fieldSENSE60 using the app available from www.fieldsense.com.

FALL DETECTION & ALARM

The fieldSENSE60 is equipped with a tri-axis accelerometer which is able to detect if the device experiences a fall.

• This is immediately activated when the device is on, and should the device detect a fall of approx. 2m it will sound the alarm.
• The alarm can only be cleared by switching the device off.
• This is to draw attention to a climber who may be in need of support.
• The alarm, if uncleared, will continue until the batteries are exhausted.

REPLACING THE BATTERIES
When the Low Battery Indicator begins to flash, replace the batteries.

• It is NOT possible to charge the device through the USB port, this is exclusively for access to data and voice logs.

• Open the elastomer flap at the bottom of the fieldSENSE60 revealing the battery lid screws (16).

• Remove the screws (16) and lid (14) and slide out the old batteries (15). Dispose of these correctly
  REMOVING THE BATTERIES FOR AN EXTENDED PERIOD OF TIME WILL CAUSE THE DEVICE TO LOSE TIME ON THE INTERNAL CLOCK. THIS IS CORRECTED BY PLUGGING IT INTO THE USB CONNECTION ON A PC RUNNING THE FIELDSENSE APP.

• Insert 2 x new AAA (LR03) batteries (15), paying attention to the polarity thereof.

• Replace the battery lid (14) and retighten the screws (16).

• Securely close the elastomer cover to ensure the dust & moisture seal remains intact.

HARNESS ATTACHMENT

Elastic strap

• Insert the one end of the elastomer strap through the strap harness attachment bars (8) as shown in (17).
• Pass the other end of the elastomer strap around the webbing on the harness you wish to attach it to.
• Feed the other end of the elastomer strap through the bars as above.
• Pull on both ends until securely fastened to the webbing.

Clip & coiled lanyard

• Attach the coiled lanyard to the lanyard attachment point (11) on the fieldSENSE60.
• Pass the other end of the coiled lanyard through the harness clip mechanism as shown in (19), pulling it back to clip in place as shown in (20).
• Set the rear clip section behind the webbing you wish to attach to and press the front clip section firmly into it until both ends clip (21).
• The fieldSENSE60 can now be pressed into the clip and easily removed as needed with a single handed operation.
