Powering On your EKGraph Device

Powering on your EKGraph device is very simple. Simply Press and Hold the PLAY button for 3 Seconds. The LCD screen will light up and the Device will be Ready to record and EKG.  


PROBLEM: The EKGraph is not powering on even after holding the play button for over 3 seconds. 

SOLUTION #1: You may not be pressing the power button hard enough. EKGraph was designed to not power on by accident. You may not be pressing hard & long enough.

SOLUTION #2: Device my have a low battery. Please charge your device and try again. 

SOLUTION #3: Unplug device from Charging. Device will not power on while being charged.

SOLUTION #4: Reset the device by holding the power/play button for 10 seconds. Device will reset and restart and should power back up. If that doesn't help please contact us.

Recording your first EKG / ECG

Once Powered On, you will see a flat EKG line on the LCD screen. This means your EKGraph is Ready to Record an EKG. To record a proper "clean" EKG you will need to place your wrists on a flat surface such as a table.


Rest the extremities (hands, feet, chest) that you are recording on a flat surface.

Place your palms or fingers firmly (but not too tight) against the metal sensors located on the left and right side of the device. You will start seeing an ORANGE wave form tracing line. 

This means the device is establishing connection and stabilizing your reading. Continue holding your hands or fingers on the device. In a few seconds the tracing line will become GREEN

This means that the EKG recording has as started and the device is counting down time. Your first recording will be 10 seconds long. Once the 10 seconds are up the EKGraph will show you an immediate EKG analysis. 

You now recorded your FIRST ever EKG on the EKGraph! 


PROBLEM:EKGraph not recognizing my hands, fingers, etc. Your hands/fingers may be too dry and the EKGraph cannot establish a signal. Another problem can be that your hands or device sensors are covered with oil.

SOLUTION: Wipe your hands/fingers and the EKGraph sensors with an alcohol wipe or wet towel.

PROBLEM: The EKG tracing line stays ORANGEand cannot finish recording an EKG.

SOLUTION #1: You may not be still enough. Try to keep steady. Press firmly but NOT too hard. Rest your Hands on a table if necessary.

SOLUTION #3:See Above: EKGraph not recognizing my hands, fingers, etc

TIP: Your first EKG should be a TEST
