Indications for use

The Quantum-III measures or calculates the following values:

Resistance, Reactance, Impedance, Phase Angle, Body Fat* (FAT), Fat-Free Mass/Lean

Body Mass* (FFM/LBM), Total Body Water* (TBW), Intra-Cellular Water* (ICW), Extra-

Cellular Water* (ECW), Basal Metabolic Rate* (BMR), Daily Energy Expenditure* (DEE),

Body Mass Index (BMI)

* Estimated

Intended population / usage

The Quantum-III is intended to be used on normally healthy individuals aged 12-90, who

have not had an arm or leg amputated. It is not intended to diagnose or treat a disease or

medical condition.

Contraindications

No known contraindications exist.

INTENDED USAGE

Warnings

Bioelectrical Impedance Analysis (BIA) devices, like the Quantum-III, operate by introduc-

ing an alternating current (AC) signal into a body, and then detecting how that signal is af-

fected by the body. This device should not be used on subjects with any implantable elec-

tronic devices such as pacemakers or implantable cardioverter defibrillators (ICDs).

Women who are tested with this device should not be pregnant or suspected of being preg-

nant. Besides increased inaccuracy of readings in this condition, the effects of the measure-

ment on the fetus are unknown.

Precautions

Failure to follow the subject preparation and testing procedures (detailed on pages 15-16)

may result in incorrect readings.

The person performing the BIA tests must also be able to demonstrate proficiency in elec-

trode placement. See page 15 for conducting a proficiency test.

To charge the Q3, first connect the power cord to

the charger, and plug it into the wall. Second,

plug the charging cable into the round Subject

Cable/Charger connector in the center of the

back panel. You will notice an indentation on

the charger cable connector. This indentation

must line up with the arrow on the back panel to

insert the connector. The indentation on the connector must

line up with the arrow.

•Batteries OK

While the charger is plugged in and the batteries are charging,

this light should blink once per second. Once the batteries are

fully charged or the charger is disconnected, this light will stop

blinking and turn off.

•Rapid Charge

This light turns on when the batteries are charging quickly. How long the system stays in

this mode depends on how low the batteries were when the Q3 was plugged in.

•Top-off Charge

When the charging system detects that the batteries are close to being fully charged, it

slows the charging rate to protect the batteries.

•Done Charging

Once the batteries are fully charged, this light will turn on. At this point, the system enters

a maintenance mode, and the batteries are monitored to ensure that they remain fully

charged.

If the batteries are low, it can take up to five (5) hours for the batteries to become

fully charged,. It is recommended the Q3 be allowed to charge overnight. The Q3

uses a “smart” charging system, which protects the batteries from being overcharged.

Therefore, it is perfectly safe to leave the Q3 plugged in when not in use.

Please note: While the Q3 is plugged into the charger, it cannot be used to perform

BIA tests or to do system maintenance. If the Q3 is turned on while charging, it will

either display a message saying “batteries charging” or “batteries fully charged”.

Also on the back panel is an array of four lights which indicate the charging

status of the Q3. These lights will only turn on if the Q3 is plugged in. The

lights have the following meanings:

1. Self Tests

The Q3 will begin by performing a series of self-tests to ensure

the internal circuitry is properly calibrated and working correctly.

This takes approximately 15-20 seconds. It is imperative the

charger not be plugged in while the self-tests are in progress. This

will confuse the Q3 and make some future tests fail. If this hap-

pens, turn the Q3 off and then back on to clear the error.

2. Title Screen

After the tests have completed successfully, the Q3 will display

the title screen for approximately five seconds. In addition to the

name of the analyzer, this screen will also show you the version

information for the firmware (program) running on the Q3. If you

ever have a problem with the Q3 and need to call tech support, the

technician will ask you for this information.

3. Current Date and Time

The Q3 will spend another five seconds showing you the current

date and time. Please check to ensure this date and time is correct

because any reports printed or BIA records saved will have this

timestamp. To change the timestamp, you can either press “0” to

go to the Change Time form, or you can wait and come back to

this page from the main menu later.

(See Introducing the Main Menu and Changing the Time and Date.)

4. Main Info Page

If the subject cables are plugged into the Q3 and connected to a

test subject, this page will show the current measured resistance

and reactance; along with the calculated impedance and phase an-

gle. Otherwise, this page will only contain the message that the

subject cables are disconnected. For a brief description of the

measurements’ meanings, see the section: “What Do the Results

Mean?”

WHAT HAPPENS WHEN THE Q3 IS TURNED ON?

If the Q3 is turned on and is plugged into the charger, it will display a message about the

battery status (see “Charging the Q3”). If the Q3 is turned on and is NOT plugged into the

charger, the following sequence of events will occur:

Navigation through the program that runs on the Q3 is done by use of a couple of menus. To

get to the main menu, press the MENU key. When you do, the top four lines of the menu

will appear on the screen. For reference, the entire menu is shown below on the right. Use

the up and down arrows to move the blinking cursor through the list of screens. When the

cursor is next to the screen you want, press the ENTER key.

Here is a brief introduction to the various screens listed in the

main menu:

•Main Page

You were introduced to the main page in the previous section.

This screen shows you either the BIA readings currently being

measured (if cables are currently connected to the patient) or

the message saying the cables are disconnected.

•Time & Date

This screen is shown briefly when you turn on the Q3. It dis-

plays the current time and date which will be printed on re-

ports or saved on BIA records. This screen provides the op-

portunity to update the Q3’s system clock.

•Subject Input

This screen is used to enter patient data to calculate body com-

position. Once all of the necessary data has been inputted,

you will have the opportunity to view body composition re-

sults and print reports.

•Edit Preferences

The preferences screen allows you to configure the behavior

of the Q3. You can set units for height and weight, time and

date formatting, etc.

•Storage Status

Going to this screen will show you how many records are

currently stored on the Q3 and much space remains in the

memory. For more information, refer to “Storage Status”

•Run Self Tests

Selecting this menu option will re-run all of the tests that are

performed every time the Q3 is turned on.

•About

This menu option takes you to the title page that you were

introduced to in “What Happens When the Q3 is Turned

On.”
