When the [LOW BATTERY mark] appears in the display, replace both batteries with new ones at the same time. Do not mix old and new batteries. It may cause the battery life to be shortened, or the device to malfunction.
The [LOW BATTERY mark] does not appear when the batteries are drained. Battery life varies with ambient temperature and may be shorter at low temperatures. Remove batteries if the device is not to be used for a long period of time. The batteries may leak and cause a malfunction. Use the specified batteries only. The batteries provided with the device are for testing the monitor performance and may have a shorter life.
2. Fastening the Cuff
- Wrap the cuff around your wrist about 1 cm above your hand as shown in the figure.
- Fasten the cuff tightly using the [Velcro strip].
Note: For proper measurements, fasten the cuff tightly and measure on a bare wrist.
How to Take Proper Measurements
For best accuracy in blood pressure measurement:
- Sit comfortably at a table. Rest your arm on the table.
- Relax for about 5 to 10 minutes before measurement.
- Raise your hand so that the cuff is at the same level as your heart.
- Remain still and keep quiet during measurement.
- Do not measure right after physical exercise or a bath.
We recommend you to rest 20 or 30 minutes before taking measurement. Measure your blood pressure at about the same time every day.
Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed.)
After Measurement
After measurement, press the [START button] to turn off the power. Remove the cuff and record your data.
Note: The device is provided with an automatic power shut-off function which turns off the power automatically one minute after measurement. Allow at least ten minutes between measurements on the same person.
Measurements
Note: The UB-510, once used, will provide an inflation appropriate to the user, based on the previous measurement.
Normal Measurement
- Sit comfortably with the cuff at the same level as your heart and relax.
- Press the [START button]. The average recorded blood pressures and data number are displayed briefly. Then the display changes as indicated in the figure on the right as measurement begins. The cuff starts to inflate. It is normal for the cuff to feel very tight.
- Note: If you wish to stop inflation at any time, press the [START button] again.
- The measurement starts automatically when pressurizing starts, and the [heart-icon] blinks.
- When measurement is complete, the systolic and diastolic pressure readings and pulse rate are displayed. The cuff exhausts the remaining air and completely deflates automatically.
- Press the [START button] again to turn off the power. Remove the cuff.
Note: The device is provided with an automatic power shut-off function. Allow at least ten minutes between measurements on the same person.
Notes For Proper Measurement
Sit down in a comfortable position. Place the arm to be used for the measurement on a table or other support so that the center of the cuff will be at the same height as your heart.
Relax for about five or ten minutes before taking a measurement. If you are excited or depressed by emotional stress, the measurement will reflect this stress as a higher (or lower) than normal blood pressure reading and the pulse reading will usually be faster than normal.
An individual's blood pressure varies constantly, depending on what they are doing and what they have eaten. What you drink can have a very strong and rapid effect on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the device may have difficulty determining your blood pressure.
Should the device detect a condition that is abnormal, it will stop the measurement and display an error symbol. See pages 3 and 4 for the description of symbols.
This blood pressure monitor is intended for use by adults only. Consult with your physician before using this device on a child. A child should not use this device unattended.
Operation Mode
1. Normal measurement with storing data
(Refer to page 8)
Press the [START button]. Blood pressure is measured and data is stored within the device. The device can store the last thirty sets of data.
2. Recalling data
Press and hold the [START button] to recall the data. Stored data are automatically displayed in order from the last data.
3. Clearing data
Remove batteries to clear all data. Re-install them again.
What Is An Irregular Heartbeat?
Model UB-510 blood pressure monitor provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. An irregular heartbeat is defined as a heartbeat that varies by 25% from the average of all heartbeats during the blood pressure measurement. It is important that you be relaxed, remain still and do not talk during measurements.
Note: We recommend contacting your physician if you see this [heart-icon] indicator frequently.
Pressure Bar Indicator
The indicator monitors the progress of pressure during measurement.
Diagram shows stages of measurement: 'Inflation in progress', 'Measurement in progress', and 'Inflation complete', with bar segments indicating pressure.
WHO Classification Indicator
Each six segments of the bar indicator correspond to the WHO blood pressure classification described on the next page.
WHO Classification Indicator
- Severe hypertension
- Moderate hypertension
- Mild hypertension
- High normal
- Normal
- Optimal
: The indicator displays a segment, based on the current data, corresponding to the WHO classification.
Example
Moderate hypertension: Displays systolic, diastolic, and pulse rate readings.
Mild hypertension: Displays systolic, diastolic, and pulse rate readings.
High normal: Displays systolic, diastolic, and pulse rate readings.
About Blood Pressure
What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured first thing in the morning while one is still at rest and before eating.
What Is Hypertension And How Is It Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended can cause many health problems including stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication under a doctor's supervision.
To prevent hypertension or keep it under control:
- Do not smoke
- Reduce salt and fat intake
- Maintain proper weight
- Exercise regularly
- Have regular physical checkups
Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor's office may cause apprehension and can produce an elevated reading, 25 to 30 mmHg higher than that measured at home. Home measurement reduces the effects of outside influences on blood pressure readings, supplements the doctor's readings and provides a more accurate, complete blood pressure history.
WHO Blood Pressure Classification
Standards to assess high blood pressure, without regard to age, have been established by the World Health Organization (WHO), as shown in the chart on the right.
Blood Pressure Variations
An individual's blood pressure varies greatly on a daily and seasonal basis. It may vary by 30 to 50 mmHg due to various conditions during the day. In hypertensive individuals variations are even more pronounced. Normally, the blood pressure rises while at work or play and falls to its lowest levels during sleep. So, do not be overly concerned by the results of one measurement. Take measurements at the same time every day using the procedure described in this manual to get to know your normal blood pressure. Regular readings give a more comprehensive blood pressure history. Be sure to note the date and time when recording your blood pressure. Consult your doctor to interpret your blood pressure data.
Chart shows typical fluctuation within a day for systolic and diastolic blood pressure, with time markers from midnight to noon.
