R F P e r s o n a l Mo n i t o r Personal & Area Monitors US Patents 6,154,178 5,600,307 5,168,265 International Patent Pending • 100 kHz to 100 GHz • Shaped Frequency Response Matched to Your Standard • Data Logger Records Continuously – more than 30,000 data points • Five High-Intensity LED Level Indicators • Tri-Sensor Handles All Types of Fields • Two Adjustable Audio Alarms • Adjustable Vibrator Alarm • Long Battery Life • Patented Design DESCRIPTION The new Nardalert XT family of RF personal monitors is designed to satisfy the needs of virtually all individuals who use an RF personal monitor. Models are available that closely conform to all major worldwide standards. The adjustable alarm feature allows one alarm to be set at a level equal to the upper tier of two-tier standards, such as "Occupational" or "Controlled" limits, while the second alarm can be set to the lower tier, such as the "Action" or "General Population" limits. The ultra-broadband sensors cover almost the entire usable RF spectrum in a single monitor. The unique tri-sensor design handles every possible signal format, from complex multi-signal communication environments to military platforms with both communications and radar signals. The five flashing high-intensity LED level indicators can be seen while wearing the monitor, even outdoors in the sun. There are four different ways to wear the monitor – pocket clip, belt clip, soft case with belt clip (optional) and soft case for climber’s harness (optional). The audio alarm has two distinct sounds that are associated with the two different alarm thresholds. Both alarm thresholds can be adjusted using the optional Interface Kit.

The user can select an audio alarm, a vibrator alarm, both audio and vibrator, or an optional remote vibrator. The remote vibrator can be used in areas with high ambient noise when the user is wearing heavy clothing that would prevent the detection of the internal vibrator. The data logger is always on. The logging interval can be adjusted using the optional Interface Kit. At the default setting, the average field strength is logged every five seconds with the data logger retaining more than 40 hours of information before it starts to write over the oldest data. Either one or both of the...

There are four series of Nardalert XT RF monitors. Within each series, the specifications are essentially identical except for the sensor “shaping.” Each specific standard or guidance requires some differences in the sensor design and calibration. The four Nardalert XT series are: 8860 Series: This is the full-featured, Nardalert XT series that includes all the user-adjustable parameters plus the ability to log more than 30,000 data points automatically whenever the monitor is turned on. The data-logger feature can be used to analyze personnel exposures in order to improve operations. Or it...

Data Logged data is downloaded. Once it is downloaded you can: Analyze it on screen with a variety of tools. For example, even though the data is collected in terms of five-second average exposure (default setting), the User’s Software allows you to smooth the data and average it over longer periods of time Create reports Export the data to other programs such as word processors, spreadsheets, or data bases The cursor can indicate value, data point and time Header defines data that is being viewed Monitor model and serial number that logged the data Model 8865 Interface Kit The Model 8865...

Notes: a Accuracy specified as the mean of the radial and vertical orientations (10 to 1600 MHz) and mean of the vertical and horizontal orientations (1600 MHz to 50 GHz) b Remote vibrator, P/N 11110100, is available as an option. It operates from its own battery. c Percent of Standard percentages are in terms of equivalent plane-wave power density relative to the Standard or Guidance. d The Interface Kit is required to make adjustments to the monitor settings and/or to download logged data. e 8862 Series monitors do not include memory.
