Introduction
The Ipos Rein Sensors system consists of two sensors, to be placed between the bit and the rein on the left
and right side of the horse. The system measures the amount of pressure applied to the bit. The total
amount of pressure is a combination of what the rider and the horse produce. By analyzing the pressure
patterns, the software can calculate the base contact, the rider’s symmetry and the aids you’re giving.
The data is received by the Ipos Training Application. The amount of pressure can be shown in real-time on
either the rider’s smartphone or a coach’s smartphone.

Safety
This chapter is about working safely with the sensors. Carefully read all safety messages in this chapter.
Electrical safety
Always use a power source that is compatible with the sensors. Refer to Charger requirements for more
information. If you have any doubts, consult your dealer.
The sensors may interfere with delicate electronic devices (for example, but not limited to, medical or
aviation equipment). Consult with technical staff at your location before using the sensors near sensitive
electronic equipment.
Do not leave the sensors on the charging pad for an extended period of time without supervision. Remove
the sensors from the charging pad in case of a lightning storm to prevent damage from a power surge.
Remove the sensors from the charging pad if they are not used for an extended period of time.
Physical safety and cleaning
Prevent damage to the sensors and store them in a dry and clean place, out of reach of children and horses.
Do not store the sensors in a stable or storage room where they can be damaged by heavy items or horses.
Damage due to incorrect storage is not covered by the warranty.
Do not open the casing or remove the screws that maintain the stability of the casing and interior.
Never push objects of any kind into the sensors through openings. This can cause fire or an electrical
shock.
Do not use the sensors near water. Never spill liquid of any kind on the sensors. Do not use liquids or
aerosol cleaners on the sensors.
Take the sensors off the charging pad before cleaning. Remove leather covers and use a damp cloth for
cleaning.
Safe usage
Follow the mounting instructions. Do not mount the sensors while a rider is on the horse. Do not
disconnect both reins at the same time.
The sensor will be damaged when overloaded. When forces over 1000 Newton are applied, the
sensors will be damaged beyond repair.
Do not subject the sensors to impact or physical shocks while data is being recorded.
Service related safety instructions
There are no user serviceable parts inside. Do not attempt to service the sensors as opening or
removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to
qualified service personnel.
Remove the sensors from the charger and refer servicing to qualified service personnel under the following
conditions:
•the power supply plug is damaged;

Operation
Before using the sensors, take a moment to familiarize yourself with the supplied accessories and the
names of the sensors’parts. Refer to the chapter Description.
LED indicator
The LED indicator on the sensor can light up in different colors.
•Green: The sensor is switched on;
•Blue: The sensor is connected via Bluetooth;
•Light Blue: The sensor is streaming data or being calibrated;
•Red: The remaining battery power is low;
•Off: The sensor is in low power, sleep mode.
Charging the Rein Sensors
The sensors are powered by a rechargeable lithium-ion battery. With a full battery the sensors can be used
for approximately 12 hours, depending on local circumstances. If the sensors are not used for a long time, it
may be necessary to charge the sensors before use.
A blinking red LED light indicates the battery capacity is below 10%.
To prevent damage to the batteries, avoid discharging the sensors completely.
1 Place the sensors on a wireless charging pad
Place the sensors on a wireless charging pad with the charging side down, facing the pad. The sensors are
compatible with most charging pads.
The best charging location on a charging pad is indicated on the pad.
2 Check indicator light
The LED indicator on the charger lights up blue to indicate the sensor is charging. The indicator lights are
located on the front of the charger. If you’re using the Ipos Technology Duo Charger, you will see two LED
indicators light up blue if both sensors are on the pad.
3 Fully charged
The charging time depends on the power of the charging pad. The LED indicator of your charging pad will
flicker red when the batteries are fully charged. Refer to the manual of your charging pad for more
information.
4 After charging
Remove the sensors from the pad. The sensors will reset automatically and will reconnect to the
smartphone the next time they are used. If you take the sensors off the charging pad before they are fully
charged, they will reset and turn on automatically. When the sensors reset you will not lose any data.

Connecting sensors to a smartphone
Connect the sensors to your smartphone to receive data. Make sure that Bluetooth is enabled on your
smartphone.
1 Permission to use GPS
The Ipos application will require you to enable GPS tracking in order to receive continuous data. Your
smartphone will ask you permission through a popup. Select Allow to enable GPS tracking.
2 Sensor setup
1Open the MENU in the upper left corner.
2Select REIN SENSORS.
3Choose Left Sensor and select a sensor to connect as your left sensor.
4Choose Right sensor and select a sensor to connect as your right sensor.
5Select Finish configuration to start your training.
The sensors will need a little time to be initiated before you can start measuring tension data.
3 Check connection
To make sure that your sensors are connected, check the LED indicator on the rein sensors. If the LED
indicator lights up blue, the sensors are connected to your phone. The LED indicator will be light blue when
the sensors are streaming data.
4 Check data coming in
To check the data coming in, start a training and swipe to the left. Once the sensors have been
synchronized with your phone, a left and right value is displayed presenting the force applied in kilograms.
The most accurate way to check is by hanging a known weight on the clip and holding the rein connection
bar. Your app should now display that weight on the bars. If nothing happens, you might have to restart
your training.
A calibration may be needed to adjust the offset value if the app is not displaying the correct data. The
sensors are very sensitive to temperature and climate circumstances. We recommend to do a calibration at
0 kilograms at the start of each measurement. Refer to Calibrating the Rein Sensors.

User Manual
14
Calibrating the Rein Sensors
The sensors provide accurate tension values with a sensitivity of 20 grams. Its inner workings depend on
external factors such as temperature and humidity. You can calibrate the sensors to adapt them to the local
circumstances. Always perform a calibration if you turn on the sensors for the first time.
It is recommended to perform a calibration before every measurement to correct for any changes in
local climate and circumstances. If you do not calibrate the sensors, the measurements will be based
on the most recent calibration.
1 Disconnect the sensors
Make sure the tension on the sensor is zero. Lay down the sensors and make sure there is no tension or
pressure on the sensors or any connected reins and hooks.
It is not sufficient to release the reins with the sensors connected between the reins and the bit
when you are calibrating the sensors. There will still be tension on the sensors from the weight of the
sensors and the reins or from movement of the horse’s head.
2 Calibrate the sensors
1Open the MENU in the upper left corner.
2Select REIN SENSORS.
3Select Left Sensor.
4Select Calibrate.
The calibration will take a few seconds. Repeat for the Right Sensor.
3 Check
To check if the calibration was successful check if the measurement data is zero at zero pressure.
1Open the MENU in the upper left corner.
2Select START TRAINING.
3Swipe left to view the rein tension measurement.

Mounting the sensors
You can attach the sensors to the bridle on the horse or before you put on the bridle. If necessary, make
sure to calibrate the sensors before connecting it to the horse.
You can watch a tutorial video in our Shop at: www.ipostechnology.com
Dismount from the horse. Do not connect rein sensors while there is a rider on the horse. If a horse
spooks with one rein disconnected the rider may have little control over the horse and fall off.
1 Mount the sensors
1Connect one of the clips to the bit.
2Disconnect the rein from the bit.
3Connect the rein to the bar at the other end of the sensor.
4Repeat the steps at the other side of the horse.
2 Check left and right
The sensors are interchangeable, so it does not matter which sensor is connected to which side of the bit.
However, on your phone they are connected as Left Sensor and Right Sensor, so you want to connect
them to the correct side of the bit.
If you have accidentally swapped the sensors, it is possible to swap the data presentation in the app.
There is no need to swap the sensors on the horse.
1Open the MENU in the upper left corner.
2Select REIN SENSORS.
3Select Swap sensors.
Do not disconnect both reins simultaneously. Always keep control over the horse by having one of
the reins connected.
