What is EasyLevel

EasyLevel is not an instrument for precision measurement of angles but a tool for leveling caravans and motorhomes. EasyLevel defines a zero point against which it measures the angle, meaning it measures relative angles against a defined zero point.

How does it work

EasyLevel consists of several applications that communicate via Bluetooth/BLE with the sensor unit, which uses an angle/gyro component to measure tilt/gravity.

What is the accuracy/operating temperature range

The sensor's accuracy is approximately ±1 degree in the temperature range of -20°C to +40°C, and approximately ±0.5 degrees in the range of 0°C to +40°C (often better). The recommended operating temperature range for the sensor is 0°C to +40°C (mainly due to the battery's properties at sub-zero temperatures). The extreme temperature range is -20°C to +50°C (which may affect the battery and sensor performance).

Installation

1. Battery Installation

1. Unscrew the lid.
2. Slide insert a CR2450 battery (with the + marking visible/upwards).
3. Press down the battery until it clicks into place.
4. Screw the lid back on. To facilitate mounting on the vehicle, there are also arrows on the lid that must match the arrows on the circuit board.

2. Application Installation

1. Download and install the "EasyLevel RV" application from your preferred app store.
   This application is designed to be used specifically with motorhomes.
2. Start the application.
3. Accept EasyLevel RV's permission requests (these may vary), if not accepted the application cannot connect (BlueTooth) to the sensor.
4. A successful connection is indicated by a green sensor icon on the application main screen.

If there is an issue connecting to the sensor, please see the “troubleshooting” chapter for further steps.

The sensor is now paired to the application.
The sensor's tilt is illustrated by the movement of the vehicle in the application and shows the degree of tilt.

The sensor is now ready for installation in/on the vehicle. Note the arrows on the sensor indicating orientation. One (any) of the arrows must point forward for proper function!
To facilitate this, there are also arrows on the lid.

3. Vehicle Installation

To achieve the best possible functionality, the placement of the sensor is crucial.
Some factors that affect performance are:

• Sensor placement: Avoid placing the sensor (if possible) inside the caravan or under/inside/near large metal objects.
• The distance between the sensor and the Android/iOS device: The maximum distance is approximately 10 meters and is highly dependent on the Android/iOS device.
• The radio of the Android/iOS device: Different manufacturers have varying quality solutions, and the software on the Android/iOS device can also affect performance.

A possible placement is inside the overhead cabinet, is relatively close to the Android/iOS device and has no large metal objects nearby (if the cabinet is non-metal).

EasyLevel RV Application

The EasyLevel RV application is relatively simple to get started with and easy to use.

The application consists of a two different main screen views, which one to use can be selected in the settings menu.

Default main screen (bubble view)

Classic main screen 

Pressing the speaker icon (bottom left) turns the auditory feedback on or off. The volume can be adjusted in the settings.

Pressing the gear icon (bottom right) brings up the settings menu. See the next page for more information.

 If neither the front/back nor left/right are leveled, the wheel with the highest error will be indicated and height correction in cm (if enabled).

When both front/back and left/right are within the defined0 level, then all indicators will turn green.

Settings

·     Generic – Settings for language, views, angles ·     Sensor – Settings for the sensor and sensor placement ·     Resolution – Settings for degree resolution ·      View – Selection of main screen ·     0° Level Tolerance – Settings for 0° tolerance ·     0° Level Memory – Selection of 0° position to use ·     Set 0° Level – Settings for 0° level ·     Audio – Volume control for audio feedback ·     Height Correction – Settings for height correction view ·     Help – Help menu and safety instruction

Generic

Angle: ·       Relative degrees – Shows degrees based on defined 0 levels, preferred way to show degrees ·       Absolute degrees – Shows absolute degrees independent of defined 0 levels Language: ·       Language selection – The application selects the device language as default; if not found, English is selected. Here, this can be overridden and manually selected.

Sensor

Displays the current connected sensor address (only available in Android). Pressing the "New Sensor" button prepares the application to pair a new sensor. Note that if there is an already paired sensor, it will be disconnected.  Placement: It's important that the sensor is mounted with at least one of the arrows on the circuit board (also available on the lid) facing the forward. ·       Mounting with broadside facing forward ·       Mounting with side facing forward This is selected and indicated by a green marking. Advanced: ·       Gyro on/off - If you want a very quick response to tilt changes, the gyro should be on. If you want higher accuracy, the gyro should be off. Note that the gyro is significantly affected at low temperatures, so turning off the gyro at low temperatures can improve accuracy. The response will be slightly slower when the gyro is off.   ·       Scan Device Name – (Only available on android) If you have an old sensor (lid without arrows), older android version or having a lot of issues connecting then selecting this might improve the connection process, normally this is not needed

Resolution

The accuracy/resolution of the displayed angle on the main page can be set from 0.05° to 2.0°. Highest is ±0.05° and lowest is ±2.0°.   Note that higher resolution results in more noise/sensitivity in the angle display on the main page.

View

Selection of main screen view, bubble spirit level view or classic view.

0° Level Tolerance

Under 0° Level Tolerance, the maximum/minimum tolerance for the 0° level is set. This determines how much the tilt can deviate from the defined 0° level before the indicators change from green to either red or blue, and if enabled, the audio feedback starts. ·       Left/Right: plus/minus degrees from defined 0° level left-right ·       Back/Front: plus/minus degrees from defined 0°level front-back  It is recommended not to have too narrow tolerance due to the nature and accuracy of the sensor. However, to get as much detail and keep the indicators on the main screen active as much as possible, the 0° level tolerance can be set to its lowest value of 0.05° and the resolution to ±0.05°. This will provide a very high-resolution configuration, with the indicators active as much as possible, and a very sensitive system

0° Level Memory

If needed, up to four 0° level positions can be stored and used as custom 0° levels.  This feature can be useful when, for example, you want to have several custom 0° levels, such as one for showering and one for normal use, or one for emptying the waste tank. The used memory position is marked in green. This feature is not mandatory to set up, and position 1 is the default used by the application.

Set 0° Level

Setting a user 0° level is recommended to compensate for any unevenness where the sensor is mounted and to account for sensor tolerances. Left/Right: ·       L+ = Adjusts the left side up ·       OK = Set the current tilt as the user 0° level ·       R+ = Adjusts the right side up ·       0.0° = Resets the custom-defined level to zero Back/Front: ·       B+ = Adjusts the back up ·       OK = Sets the current tilt as the user 0° level ·       F+ = Adjusts the front up ·       0.0° = Resets the custom-defined level to zero Note that the custom 0° level is saved when the dialog is closed pressing the red x at top right corner.

Keep in mind that if you install the sensor in an empty space and then fill it with equipment, the angle may be affected due to weight changes and bending of the substrate/floor.

The following procedure is recommended to setup a user 0° level:

1. Level the vehicle to your desired 0° level, i.e., at the desired tilt.
2. If wanted, select a 0° level memory position to use (0° Level Memory menu).
3. Set the current level by pressing "OK” (press a few times so it stabilizes).
4. The 0° offset tilt is displayed under the vehicle icon.
5. Close the dialog, now the user 0° level is stored

Audio

Volume control for audio feedback. The audio tones for front/back feedback and left/right feedback differs from each other to simply the setup Front/Back Volume: ·       Volume level for front/back correction. Left/Right Volume: ·       Volume level for left/right correction.

Height Correction

These correction numbers are only for guidance and may vary depending on factors such as tire pressure, the accuracy of the sensors and installation. The accuracy is ±0.5 cm regardless of the chosen resolution. 

Show Correction: ·       Enables the display of correction in centimeters on the main screen. Enter Track Width (front): ·       The distance between the front wheels (wheel center) in centimeters. Enter Track Width (back): ·       The distance between the rear wheels (wheel center) in centimeters. Enter Wheelbase: ·       The distance between the front wheel axle and the rear wheel axel in centimeters.

The height correction should be based on the greater of the front or rear track widths for left/right adjustments. In certain cases, equalizing the front and rear track widths may enhance the setup.

Setup Guide

The procedure below is for the EasyLevel application but it’s the same principes for the EasyLevel RV application.

1. Define 0-level

It is advisable to set up the 0-level before camping / new installation to compensate for uneven mounting surfaces and sensor inaccuracies. Follow the instructions under "Set 0 Level" in the manual to establish a 0-level.

2. At camping site

Start the EasyLevel RV application on your phone a little before reaching the setup location, as it may take some time for the connection between the phone and the sensor to establish. The driver/operator can immediately see the tilt of the caravan/motorhome during setup and easily make corrections. A guide showing how much to raise or to lower is also displayed (if the distance has been defined in the application).

3. Setup the vehicle

Use EasyLevel RV to facilitate the setup and indicate how/where adjustments are needed.

Troubleshooting

Important: Before following this guide, document any 0-level position settings and/or height corrections if they have been made!

Troubleshooting Steps:

1. Remove the battery from the sensor
2. Wait 5 minutes to ensure the sensor is completely discharged.
3. Uninstall the EasyLevel RV application from your smartphone.
4. Check that the battery is new and in good condition.
5. Insert the battery properly into the sensor.
6. Download and start the EasyLevel RV application on your smartphone. Note that it can take up to 60 seconds to establish a connection. The smartphone should be placed near the sensor during the first connection.
7. For some Android smartphones or when using an older sensor, if the problem persists after step 6, go to 'Settings' -> 'Sensor' -> 'Advanced' and select the option for a different connection method (scan device name). Then close and restart the application.

If the connection problem persists:

8. Close the EasyLevel RV application on your smartphone.
9. Download a Bluetooth scanning tool “BLE scanner” from Google Play or Apple App Store:
   • Android BLE Scanner
   • Apple BLE Scanner
10. Open the BLE scanner application and allow it to search for the sensor.

If a device named "CARATIL..." appears in the list, the sensor is functioning as it should.

Try again with steps 1-7, and possibly with another smartphone. If the problem persists, contact your dealer with information about the smartphone and operating system.

If the device "CARATIL..." does not appear, it may be due to:

• A bad battery or faulty sensor, if the sensor has previously worked follow steps 1-7 again. If it still does not work, contact your dealer.

• If the sensor has never been paired with the current smartphone, try steps 1-7 with another smartphone. If the problem persists, contact your dealer with information about the phone and operating system.
