Here are some Frequently Asked Questions about the Pro Series 2.
Q: How do I get the most reliable reading?
A: To ensure a reliable reading follow these recommendations:
- Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes before taking a measurement. Rest for at least 15 minutes before taking the measurement.
- Stress raises blood pressure. Avoid taking measurements during stressful times.
- Measurements should be taken in a quiet place.
- Remove tight-fitting clothing from your left arm.
- Sit in a chair with your feet flat on the floor. Rest your left arm on a table so that the cuff is at the same level as your heart.
- Remain still and do not talk during the measurement.
- Keep a record of your blood pressure and pulse readings for your physician. A single measurement does not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time. Try to measure your blood pressure at the same time each day for consistency.
- Wait 5-10 minutes between measurements. The wait time allows the arteries to return to the condition prior to taking the blood pressure measurement. You may need to increase the wait time depending on your individual physiological characteristics.
Q: Why do my blood pressure readings vary between wrist and upper arm units?
A: Upper arm units measure blood pressure in the brachial artery while wrist units measure blood pressure in the radial artery. In addition, there are recommendations regarding arm placement that must be considered when taking the blood pressure using wrist units. For these reasons, variation may be seen when switching between devices.
Remember, blood pressure measurements are not intended for self-diagnosis. It is recommended that you collect data from the same unit over time that you can share with your doctor who will work with you to develop a treatment plan. In addition to the blood pressure readings, it is helpful to include the time of day, type of unit used, and any specific conditions surrounding that reading.
Q: Why are my blood pressure readings different at the doctor's office than they are at home?
A: Blood pressure fluctuates constantly, which means that you will not get the exact same blood pressure reading twice in a row. Variations between home and medical office readings may be attributed to multiple factors including what is known as White Coat Hypertension. White Coat Hypertension is evident in many people. It occurs when visiting a physician's office, clinic or professional setting and results in an increased blood pressure measurement. The causes can be linked to a variety of factors present in the professional environment, including anxiety or nervousness. Home blood pressure monitoring is an effective method for trending a person's blood pressure in a static environment. It provides valuable data that can help the physician to develop a treatment plan.
Q: Does it matter which arm I use to get my reading with my digital blood pressure monitor?
A: Validation testing is conducted on the left arm. Anyone with a medical condition that requires the use of the right arm should consult with his or her physician. When using the right arm, the cuff should be applied with the tubing going down the back of the arm. There are no validation studies to support this practice and accuracy.
Q: Why do I need to wait 5-10 minutes between taking blood pressure readings?
A: The process of measuring blood pressure constricts or tightens the arteries. This causes the artery to become engorged with blood at the point of constriction. The recommended period of time is to allow for the arteries and vessels to accommodate or go back to their condition prior to the attempted blood pressure reading. The length of time varies by individual.
Q: What do the blood pressure measurements mean?
A: The American Heart Association has provided the following guidelines in the description of blood pressure measurements:

Q: How do you change the units?
A: These are the steps to change your unit of measurement:
1- Turn on your monitor.
2- Wait 1-2 seconds (before the cuff starts inflating)
3- Hold down power button for 5 seconds.
4- See the unit change
This may take multiple tries since there is a short window between turning on your monitor and being able to switch units.
Q: Is there a smaller cuff available?
Q: Why am I getting an “EE” on my blood pressure monitor?
A: An EE error appears when an accurate reading cannot be obtained. Try waiting 15 minutes and measuring again. Also, try loosening the cuff to allow blood circulation while waiting.
Q: What is the error ratio for this device? That is, what is the % of accurate readings vs. falsely high or low readings?
- Normal operating conditions (41-104 degrees F) = +/- 3mmHg
- Hotter or colder than above = +/- 5mmHg
- Pulse value = +/- 5%
Q: Does this unit measure if a heartbeat is fluctuating?
Q: Does it inflate automatically or does it have a pump?
Q: Where was the product manufacture?
A: This product is designed in California and built in China.
Q: What is the range of wrist sizes that this cuff can fit?
A: Wrist measurement = ~5" - 8.5"
Q: Is a wrist monitor as good/accurate as an arm monitor?
A: A traditional arm monitor is slightly more accurate due to the proximity of the cuff to the user's heart.
Q: Can it be used practically as a sport's Heart Rate Monitor?
A: No, it cannot be used in that manner.
