Dlsisplay and warning signal
The actual field exposure level is indicated in six steps from 5% to 200% by LEDs. The percentages refer to the proportion of the power density limit value specified in a safety standard. If the field exposure level exceeds 50% of the limit value, the device vibrates and emits a loud alarm tone. There is also a bright light in the top part of the RadMan 2 that can be easily seen from various angles. The light flashes red in time with the alarm signal. A second, more persistent alarm sounds when the 100% threshold is exceeded, warning the user to leave the danger area.
Standard compliance
The permitted limit values specified in the standards vary according to the frequency. Weighting filters in the sensors of the RadMan 2 simulate the frequency response to ensure that the alarm thresholds for all radio frequency signals are always set correctly.
Usable in near field and far field conditions
The otherwise fixed relationship between the electric and magnetic fields does not apply in the near field region. Both types of field therefore need to be checked. RadMan 2 is eqiupped with both E field and H field sensors, so it provides reliable warning regardless of the distance from the radiation source.
Minimal body effect
Personal monitors are generally worn on the person. RadMan 2 is supplied fitted with a suitable attachment and RF absorber that allows it to be fixed easily to a harness or belt. The RF absorber reduces the signal reflections caused by the body which would otherwise affect the result displayed by the monitor. If needed, the RadMan 2 can be released from the attachment with one hand in order to determine the field exposure away from the body with an isotropic directional characteristic. An elastic security cord between the device and the attachment prevents the device from being dropped.
Integrated sensor test
The newly developed sensor test provides additional assurance. The correct function of each sensor is checked every time the RadMan 2 is switched on.
Recording results with the data recorder
The RadMan 2 saves the exposure values for the E field and H field continuously and adds a timestamp to each data set. The oldest data is replaced by the latest data when the ring memory is full. Up to 100,000 events can be detected and recorded.
PC software
The RadMan 2-TS software allows the contents of the RadMan 2 data recorder to be transferred to a PC via the USB interface. The maximum exposure values that have occurred as well as the averaged values can be displayed as a table or as a graph versus time using this software. It can also display live exposure level values and it can be used to configure the RadMan 2XT. The latest version is available for free download.
