1 Introduction
The MiniRad-DX is a handheld security and inspection device that detects emissions from
radioactive material. The MiniRad-DX system can operate as a stand-alone detector or as the
roving detection part of a larger MiniRad-DX and Rad-DX network for monitoring a building or
facility.
The MiniRad-DX is not intended to be used as a personal dosimeter.
The MiniRad-DX is not certified for explosive atmospheres.

4 Software Options
Two different software applications are available to monitor and configure MiniRad-DX
radiation detectors.
4.1 DX-View Software
The DX-View is a PC-based software application used for configuring and monitoring your
MiniRad-DX and Rad-DX radiation detectors. The DX-View software is also used to view and
download data from one or more devices. Using this software, you can set radiation alarm
levels, view a real-time graph, download historical data and more. For more information, please
refer to the DX-View manual at http://www.dtectsystems.com/downloads.html.
4.2 DX-Dashboard and DX-Dashboard Setup Tool
The DX-Dashboard is a web server application, which can be used to monitor and control a
Rad-DX network remotely. It runs on either the D-tect Cloud Server or on the DX Network
Assistant (if installed at your facility). Using the DX-Dashboard, you can access your Rad-DX
network using any web-enabled device (smartphones, tablets, PCs). The DX-Dashboard Setup
Tool is needed to initially configure devices in the Rad-DX family to connect to
the DX Cloud Server. For more information about this software, go to
http://www.dtectsystems.com/downloads.html and download the DX-Dashboard manual.
Note: In order for MiniRad-DX devices to communicate on the DX-Dashboard software, one
Rad-DX device in the network needs to be connected to your network via Wi-Fi or Ethernet.
5 Maximizing Battery Life
The MiniRad-DX battery can last up to 130 hours with the mesh radio turned off, the GPS
capability turned off, and displays set to sleep after one minute. Turning up screen brightness,
keeping displays on longer, turning on the mesh radio and turning on GPS will require more
frequent recharging. Monitor the battery icon in the upper left corner of the front display to
determine when it is time to recharge the MiniRad-DX.
6 Recharging the MiniRad-DX
The MiniRad-DX is recharged through a USB connection. Either a USB port on a PC or a USB
wall charger can be used to recharge the MiniRad-DX.

8 Operation
The MiniRad-DX can operate in a stand-alone mode with information displayed directly on the
device’s front and top screens. Options for the MiniRad-DX, such as screen brightness, screen
sleep timers, and radiation units, can be set up using the following process:
1. The Home Screen will appear on the LCD screen after pressing the power button.
Figure 3: LCD Front Screen: Dose Rate and Graph
2. Pushing the upper right (power) button on the keypad again will open up the menu screen.
3. To toggle through the different screens, use the directional buttons on the keypad and the
upper left button go back to the main menu.

8.1 Communication Icons
The appearance of any network connection icon indicates that the device is currently connected
and active through the referenced connection.
Battery: The battery icon is split into 5 segments. Each segment represents 20% of the total
capacity of the battery. This icon will change to a battery symbol with a lightning bolt when the
MiniRad-DX is plugged into a USB port. This indicates that the device is charging. When 20%
or less of the battery is remaining the icon will change to red indicating a low battery.
Mesh Network: The mesh network symbol indicates that the MiniRad-DX is connected to a
greater network of devices in the Rad-DX product line.
USB: The USB icon indicates that the MiniRad-DX is communicating directly with the DX-
View configuration software.
GPS: The GPS symbol indicates that your MiniRad-DX has determined its location. GPS must
be turned on to acquire a location.
Time: The current time can be displayed in the 12 hour or 24 hour format.

8.2 Graph Screen
The lower window on the Home screen displays the detected radiation levels in a convenient
graph timeline of 90 seconds.
The numerical dose rate and the graph window display a dose rate with a 15 second average
background filter. The background filter may be adjusted by using the DX-View software.
The graph shows a 1 second average for 30 seconds for the first 30 seconds once the device is
first powered on.

8.6.1 Accumulative Dose
In order to view the total dose, the Mini Rad-DX device needs to be configured with the DX-View
software. See the DX-View Manual version 3 or later for more information.
The Mini Rad-DX measures accumulative dose levels for each device and displays it on the
home screen.
Figure 10: Home Screen with Accumulative Dose
In order to view the settings which have been configured with DX-View, first press the menu button and
then use the circular button to navigate to the Alerts menu. Then navigate to the “Alarm Threshold” label
and push right or left to switch between “Alarm Thresholds” and “Total Dose Levels”.

When the accumulate dose exceeds the settings an alarm will occur causing the device to vibrate and
sound the audio alarms, if configured to do so. Also, the Total Dose Alert notice will appear on the
screen of the device. Press the top right button to acknowledge the alarm. The Mini Rad-DX will stop
alarming, but the Total Dose Caution message will continue to appear on the screen.
Resetting the Total Dose Alarm can be done by pressing the Reset Dose button on the device in the
Alerts/Alarm Thresholds menu.
8.6.2 Alarm Options
The different levels of alarm thresholds are reported in the Alerts Menu. As the radiation level
increases and the device measures above each limit, the frequency of the alarming will increase
and the alarm level will display in the upper left corner of the dose rate screen.
Figure 13: Home Screen with Alarm Triggered
8.6.3 Setting Alarm Levels
Alarm levels can be set on the MiniRad-DX using either the DX-View or DX-Dashboard
software. Both are secured by password and prevent unauthorized modification of the alarm
levels.

8.7.2 Sleep Modes
There are 4 options for setting sleep timers for each screen. The timers for the two screens can be
set independently of one another. The options are as follows: 30 seconds, 1 minute, 5 minutes, or
never. Enabling sleep modes allows for the device to function longer between charges.
For example, say that a security guard is carrying a MiniRad-DX with them on their rounds
through the building. Typical use would have them wearing the device on their belt. To preserve
battery life, the front screen could be set to 1 minute of inactivity before shutting off and the top
screen could be set to never sleep. This allows for continuous status monitoring through the top
screen and turning on the front screen only whn further information is needed.
Regardless of the sleep settings, the MiniRad-DX will alarm and the displays will wake if
radiation above the set threshold is encountered.

9 Effective Center of Detector
The target symbol on the back label of the MiniRad-DX represents the most sensitive portion of
the detector, which is also referred to as the effective center of detection. Always point the back
of the detector toward the material or item you are measuring or scanning.
