First use
Remove plastic films from the screen and both sides of the alignment guides
and charge the device according to instructions below for two hours before
first use.
Charging the Device
To charge the device connect the charger [3] to a power outlet and connect the
USB cable to the sensor unit [1]. Only the supplied charger or a USB charger
with markings shown on figure [4] may be used for charging. Charging the
device makes you the operator of the device.
Attaching the Alignment Guide
Attach the alignment guide [2] by sliding it on the bottom of the sensor unit [1].
Buttons and Controls
Basic Operation
Power on the device by pressing the power button. The empty history view (left) or the latest measurements (right) are shown in the first view. Perform measurement using the following steps:
- Step 1 – Press the large turquoise button to enter measurement mode.
- Step 2 – Align the device with the first limb and then press the button again to start measurement. Ensure that the patient does not move during measurement.
- Step 3 – Align with the second limb and press the button to end measurement. The angle is calculated and shown on the display along with an arc that visualises the direction of the angle.
- Step 4 – Press the button again to view the measured angle together with the last four measurements. Press the power button to power off the device. If the device is not used for two minutes it will automatically shut down to save power
Angle Presentation Actual
Two angles are displayed for each measurement, the actual angle the device has been moved and the supplementary angle, which is 180º minus the actual angle. The actual angle is shown with larger numbers both in the history view and in the measurement view.
Measurement Guidelines
The EasyAngle measures rotations around the grip, as shown below. Only perform
measurements where the device is rotated accordingly. Do not perform more than
one full rotation of the device during measurement.
Delete measurement
Previous measurements can be deleted in the history view. Pressing the delete
button highlights the latest measurement, pressing the delete button again
confirms deletion. Pressing any other button cancels the deletion.
Error Modes
- Invalid Rotation – During a measurement, it is possible for the device to be oriented in an invalid direction (see Measurement Guidelines). When this happens, the display shows a spirit level where the bubble indicates how the device should be redirected to get back to a valid direction. The measurement is resumed when the bubble gets close enough to the center circle.
- Bump Warning – If the device is bumped or moved too fast during the measurement the acceleration error screen is shown and the measurement is aborted. Press the main button to restart the measurement.
- Measurement Timeout – If a measurement takes more than one minute it is aborted and the timeout screen is shown. Press the main button to restart the measurement.
Indicators
There are two indicators on the display, the battery indicator and the workflow indicator. The battery indicator has four levels, please charge the battery when the last level is displayed. The workflow indicator shows which step in the workflow is currently active, see the figures in Basic Operation.
Audio Signals
- Two Beeps – Invalid rotation during measurement.
- Two Long Beeps – Measurement timeout or bump warning.
- Single Beep – Powering on or returning from an invalid rotation.
- Single Low Pitch Beep – Button press.
- Single Long Beep – Powering off.
Hard Reset
Press and hold the power button for 30 seconds.
Care and Maintenance

Intended Use and Purpose
The EasyAngle is intended to facilitate assessment of anatomical joint angles.
The purpose of the EasyAngle is to facilitate assessments of the range of
motion (ROM) and actual angle, for example maximum extension, flexion,
adduction, abduction and rotation of any anatomical joints. This assessment
can be used for e.g. tracking of progress in a rehabilitation program or
investigation of severity of an injury.
