The Design

Measure Dip and Dip Direction or Dip and Strike with a single button press at any angle or orientation using the Reutech Digital Compass (RDC). This handheld device enables quick and easy measurement of geological features, and uniquely tagged measurements are stored on the unit for convenient transfer to PC via Bluetooth as and when required.

Simplicity

The RDC offers the opportunity to achieve much more in a far shorter time span, enabling mapping of multiple structures in a fraction of the time spent using conventional means. The elimination of tedious tasks such as levelling a unit or ensuring the unit does not move before reading the measurement guarantees a seamless experience when using the device. An intuitive menu provides a single button interface. Taking measurements and activating, cycling through, or selecting menu items is all achieved by either a long or short button press.

Once all measurements have been taken, the data is rapidly transferred via Bluetooth to a PC application for viewing.

Software

Connect wirelessly to the RDC to configure or download measurements via a user-friendly Windows 10 application. The application displays device information, individual measurements and enables addition of a user defined true or magnetic north correction factor to measurements taken. Download stored results to CSV format for processing in third party geotechnical software.

Frequently Asked Questions​ (FAQ)

A standard CR2450 battery is used.

The lifetime is dependent on the measurement and Bluetooth usage, which makes the lifetime of the battery difficult to specify.

It is important to keep these functions to a minimum when not taking measurements or downloading data.
There is a quarter turn battery cover on the rear portion of the device.
Clock-wise to close and anti clock-wise to open.
Do not over turn or the locking mechanism will be damaged.
Once open press the battery retaining clip to the side away from the battery to release it.
Insert the new battery making sure it is clipped onto place correctly before closing the cover.
Remove the battery to reset the device.
To download data enable Bluetooth on the RDC.
Connect to the RDC via Bluetooth on the Manager PC application first. Follow the procedure in the manual to read and save the data stored on the device.
Each measurement is numbered and has a date/time stamp. When this data is saved to the PC it is in a comma delimited CSV format.
Both options are available but not at the same time.
The user is able to set the magnetic declination via the Manager PC application.
A value of 0 (zero) indicates no magnetic declination.
On the device menu go to Calibrate under the Settings menu and do a long press on the red Push button to enter the calibration procedure.
Hold the device in your hand and move it around in a figure of eight movement for a minute or two to generate the calibration data.
Once the device has sufficient data it will perform the calculation and exit the calibration menu.
The accuracy of any measurement is dependent on external magnetic influences.
This could be from metallic objects in the vicinity and includes wrist watches and cell phones.
This is no different for an analog or digital compass of any type.
The user should achieve better than ±2⁰ accuracy with minimal external interference.
Remove the battery to reset the device.
The stored data on the device can be cleared from the device via the menu or via the Manager PC application.
The device offers three measurement options:
  1. Dip and Dip Direction – the default setting.
  2. Dip and Strike – the alternative setting.
  3. Compass – the device operates as a compass.
This setting is available in the menu under Mode, Display.
The user can enter the magnetic declination in the software, and when the data is saved it is corrected.
We use industrial rated components at certified to -40 °C.
It is affected in the same way an analogue compass is. The analogue compass needle will move but the perceived movement will not be as noticeable as small changes are difficult to see. On the RDC unit, the numbers will be changing dynamically which is much more visible to the observer.
The base of the unit is the reference, and the body can be at any orientation, typically the most comfortable position for measuring is used in each situation.
There is no need to use the PC’s Bluetooth menu for this.
To pair you first need to enable BLE on the device.
Run the Manager PC application and click on BLE Connection and follow the steps.
Once the device is connected to the Manager the icon on the device will change and the Manager will show the connection status and device information.
No need, this is done by the device and Manager PC application.
Enter the menu on the device and navigate to the Bluetooth menu option.
Select BLE On and then execute with a long press.
A radio icon will appear on the device display.
Once the Manager PC application has connected the icon will change to the standard Bluetooth icon.
The data is exported as a CSV file from the Manager PC application.
The menu is accessed by a LONG press on the Red pushbutton once it has been woken up.
A LONG press either enters the Menu option or confirms the option selection.
A SHORT press cycles through the menu options.
The warranty is 1 year against latent defects.
