1 Introducon
The CT007-M microR meter is a very sensitive gamma
radiation detector intended for measuring low levels of
radiation or for locating sources. The CT007-M is a small
and light instrument with a small sensor housing on the
back of the unit. The CT007-M can be used independently
as a stand-alone device, or it can be wirelessly connected to
the GammaGuard smartphone App using Bluetooth Low
Energy.
When the CT007-M is connected to the GammaGuard
app, readings are displayed on the smartphone. This allows
measurements to be taken in locations not in direct line of
sight of the device display. A telescoping handle is
available for probing at a distance. The smartphone can be
mounted to the handle, enabling one-handed operation. The
Smartphone provides a large display with access to a
feature-rich GammaGuard app. The Bluetooth connection
has a range of approximately 40 meters. The telescoping
handle can be extended with an ordinary painter’s pole. The
GammaGuard app allows you to save data to a file on the
smartphone and upload to other platforms. Earphones
connected to the smartphone can be used to improve the
ability to hear beeps or alarms in noisy environments.

3 Basic Operaon
Basic operation of the CT007-M is as follows:
1. Power unit on by long pressing (2 to 9 seconds) the
button on the front face plate.
After a few seconds, the indicator light will illuminate for
one second and the display will start showing the readings.
2. The CT007-M detector is now operating! By short
pressing (up to 2 seconds), step through the screens for
different measurement unit readings.
The detector will now automatically start radiation
detection. The OLED screen has 4 screen displays:
1) Count Rate (CPM, CPS)
2) Dose Rate (µSv/h or mRem/h)
3) Total Counts and Total Dose (C, µSv or mRem)
4) Device Information (name, mac address, version
number & battery percentage)
5) Screen Off to save battery. The detector is still
operating while the screen is off.
Individual screens, except the blank screen, can be disabled
from the app.

4 App Usage
The CT007-M can be wirelessly connected to
GammaGuard, via Bluetooth Low Energy to:
View detailed and interpreted detector data
Switch measurement display modes between count
rate (CPM, CPS) and dose rate (µSv/h, mRem/h)
Set alarms for elevated levels
Change device settings, such as the conversion factor,
enabling device count tone or device alarm
Log your data with GPS coordinates
Update your detector firmware
GammaGuard is available for both Android and iOS
system.
For iOS users, search the App Store and install the
“GammaGuard 2.0” app. It has to be 2.0 to work with the
newer devices.
For Android, search the Play Store and install the
“GammaGuard” app. Don’t use the “Legacy” version, it
does not work with the newer devices.

The Interpret screen interprets the current dose rate for
non-technical users.
The MODE switch, located in the top right of the status bar,
allows you to switch between the Dose Rate (µSv/h,
mRem/h) and Count Rate (CPS, CPM). The selected
operational units are applied to the other displays
Tapping the menu icon ≡ on the top left corner, brings up
the GammaGuard app menu, seen as the left figure in
Figure 4.4. You can chose options including “App Settings”
and “Device Settings” (CT007-M). Updated device settings
are in effect until the batteries are removed from the device.

5 Changing Baeries
The CT007-M uses two AA batteries. Follow these steps to
replace the batteries:
1) Unscrew the battery door screw;
2) Open the battery door;
3) Replace two AA batteries;
4) Close the battery door, make sure the hinge catches;
5) Drive the battery door screw back in while holding
the door closed with your thumb.
Note: It is good practice to remove the batteries if the
device is to be stored for more than two (2) months.

6 Other Useful Informaon
6.1 Data Logging
By checking “Data Recording” in settings, measurement
data will be saved on the smartphone and can be graphed
and exported. The data will be logged each “Recording
Frequency”.
6.2 Data Share by Email
If you would like to share the data, from the Archive menu,
identify the data you wish to share. Select “Export,”
followed by the preferred data type, and the ‘share’ option.
Then select “Export” to proceed. You will be prompted to
save the data locally as a file, then your method to share. If
you select “email”, your email app will open and the saved
file will appear as an attachment. (This assumes that you
have previously configured your email application.)

6.3 (Oponal) External Accessory Kits
A telescoping handle is provided for access at a distance.
The smartphone can be clipped to the handle, enabling one-
handed operation. The Smartphone provides a large display
with access to a feature-rich menu.
Figure 6.1 Telescope Handle
To attach the CT007-M to the telescope handle, attach the
attachment screw into the threaded hole on the front face of
the detector. Then turn the tightening wheel to tighten the
screw by driving the screw into the threaded hole. Figure
6.2 illustrates the attachment screw and the tightening
