How does the Pulse® Strapless Heart Rate(HR) Monitor Sport Watches read your heart rate?

The Pulse® Strapless HR Monitor Sport watch uses a patented heart rate sensing technology, called S-Pulse, designed to measure the electrical signals on your skin in the same manner that an ECG (electrocardiogram) does. While the Pulse® Strapless HR Monitor Sport watch attaches to your wrist like any other watch, it does not measure or sense your pulse at your wrist. It instead measures the electronic signals passing through your body that result from the beating of your heart.In the Pulse® Strapless HR Monitor Sport Watch, this measurement is obtained by the watch’s two metal sensors. The back metal plate of the watch is actually a primary sensor that can measure these electronic signals off your wrist. The ECG monitoring is done when you place your finger from the opposite hand onto the top sensor of the watch attached to your opposite wrist. This creates an electrical loop across your body that the watch can now read.

Are the Pulse® Strapless HR watches ECG accurate?

Yes – the S-Pulse technology, used in the Pulse® Strapless HR watches, was evaluated to assess its accuracy and reliability in obtaining heart rates, in an independent study. S-Pulse was found to be a reliable heart rate monitoring method with a proven accuracy level comparable to that of ECG recording used in clinics and hospitals.

What is an ECG (Electrocardiogram)?

An ECG or Electrocardiogram is a recording of the electrical activity of the heart over time captured and externally recorded by skin electrodes. The ECG works mostly by detecting and amplifying the tiny electrical changes on the skin that are caused when the heart muscle “depolarises” during each heart beat.

What is the difference between heart rate and pulse?

The heart rate is the number of heart beats per unit of time which is usually expressed in beats per minute (bpm). Heart rate is usually measured by sensing devices such as electrodes that pick up the electrical activity of the heart. This electrical activity of the heart regulates contractions of the heart.The pulse rate is commonly measured at any point on the body where an arteries pulsation is transmitted to the surface – often as it is compressed against an underlying structure like bone – by pressuring it with the index and middle finger. The pulse rate is a physical measure of the heart rate.

What is the importance of Heart Rate in Fitness?

Heart rate is an accurate key to determining if we are getting the most from our physical activities, and has become a good indicator of our body’s overall health and fitness. Heart Rate is the rate of heart contractions over a given time period, usually defined in beats per minute.

What is a normal Resting Heart Rate?

The normal adult resting Heart Rate typically falls between 60 and 100 beats per minute (bpm). The Heart Rates of well-trained athletes may fall at the low end of that range, and sometimes even 10-20 beats lower. To see how your fitness level is progressing over time you should measure and track your resting Heart Rate on a weekly basis. Do this before starting any physical activity so that you can become familiar with your own resting Heart Rate. For many, the resting Heart Rate will decline as they become fitter.The Pulse® Strapless HR Monitor Watch’s are an essential tool to help accomplish this, as well as for monitoring your Heart Rate during periods of physical activity, and ensuring that you are working in your target Heart Rate zone.

Why should I train with a heart rate monitor?

A heart rate monitor will help you get the most out of your training by making sure you are training at the right intensity – not under or over training. It is a exercise tool that will motivate you and give you immediate feedback to ensure you are training in your personal target exercise zone.

How do I find my personal target heart rate zone?

To find your personal target zone on the chart below, just look above your age column. For general fitness, and for those interested in weight control, it’s advisable to make sure you are spending the majority of your exercise time within your target Heart Rate zone.

Knowing your healthy Heart Rate Target Zone will enable you to align your exercise program with your personal fitness goals.Use the Pulse® Strapless HR Watch’s to Help Stay in Your Target Zone.

To be sure you are working in your personal target zone, follow these easy steps:

Begin your exercise. After 5 minutes, place your fingers on the watch sensors and press the sensors continuously for 3-8 seconds. When the beep sounds, your Heart Rate will be displayed. If it is lower than your target zone, increase the speed of your activity. If it is higher than your target zone, slow down your activity. We suggest you continue to check your Heart Rate every 5-10 minutes to understand where your Heart Rate is, and to see how it reacts to changes in exercise intensity.

Why Is my screen blank?

There are two different Heart Rate Monitor watches. If your Pulse® HRM watch sreen is blank this could be a flat battery. Take your watch to any jeweller and they will replace the battery for you.If your Pulse® QT HRM watch screen is blank it may just be turned off to save battery power. Press any button and the screen should turn on. If it doesn’t then have the battery changed at a Jeweller.

How does the Pulse QT Pro calculate the calorie count?

The micro processor of the Pulse QT PRO counts calories based on the information input by you (age and weight which is input when you set up the watch) and heart rate inputs during exercise while the chronograph function is running.So the important thing here is if you put in your resting heart rate (HR) before exercising but do not put peak HR during exercise you will get a low calorie reading based on the low HR initially input over the time of the exercise.

On the other hand, if you put in two or three high HR during exercise and don’t put your recovered HR in post exercise, the calorie calculation post exercise will be calculated on the average HR input during the exercise time, which is controlled by the chronograph, and this will give a false high calorie reading.

To get it right – start the chronograph, input your HR several times during your exercise so the watch can give an accurate average HR during the exercise period. Then the Chronograph must be stopped at the end of your exercise to stop the calorie calculation at the high HR calculation.

How does the triaxial sensor in the Pulse QT Pedometer Watch work?

A mechanical pedometer has one sensing axis. So it only works at a particular orientation. This watch uses a triaxial g-sensor. Individual sensors are configured in the x-yxz plane respectively. It senses acceleration experienced by the watch in all 3 axis continuously and looks for continuous and repetitive STEP patterns. The software will try to figure STEPS from the complex patterns created by the dynamic hand movement. So it does not have to be mounted in a specific orientation.

How do you determine which sensitivity level to set the watch to in the Pulse QT Pedometer Watch?

It is based on the step counting of the person. If the watch always counts more steps, reduce the sensitivity level. If the watch counts less than actual, increase the sensitivity level.

Can the sensor in the Pulse QT Pedometer Watch pick up the steps if the arms are not swinging freely? E.g. walking while pushing a trolly/pram?

The watch counts periodical repetitive patterns. So it has to have some kind of motion to trigger the counting. It may be the swinging of an arm, it may be the vertical (up/down) body movement during walking or running. When we are pushing a trolly in a natural way, there is a force coming from the stepping forward movement and the sensor is able to recognize such movements as steps even you do not swing the arm.

How do I reset the daily data in the Pulse QT Pedometer Watch, such as steps, calories, distance etc?

The daily reset function happens automatically at 3am if the Daily reset function is turned on. This is how you turn on the daily reset function:

  • In current time mode hold the Mode button until the ‘seconds’ start flashing.
  • When the ‘seconds’ are flashing keep pressing the Mode button as it goes through the watch set up until you come to the screen which says DAILY ZONE r SE and then press the Lap/Reset button until you get ‘ON’ flashing at you. You have just turned the daily reset function on.
  • Get out of the set up mode by holding the Mode button down until you get the current time display.

How water resistant is the Pulse QT

The Pulse QT is 50 metres water resistant – this is a classification for swimming, showering etc. (pulse®) QT should not be worn snorkelling or SCUBA diving nor any buttons be pushed underwater.Heart Rate cannot be detected underwater by this monitor but can be detected out of water whilst wet. e.g. at the end of a swim lap.
