operating your analyzer

Switching the Analyzer On
The MASTER POWER switch is located at the back of the analyzer and must be set to the ON position (indicated by a "-" on the switch) in order to operate the analyzer. Press the ON key; the analyzer performs a self-test and displays the charge remaining in the battery. When the self-test is complete the analyzer will prompt you to continue. If a key is not pressed within ten minutes the analyzer automatically turns itself off. This conserves battery power.

When the MASTER POWER switch is off battery usage is minimized. This setting is recommended when storing the analyzer. This setting is also recommended when traveling to ensure the analyzer will not be turned on accidentally. The off position is indicated by an "o" on the switch.

Checking the Battery Level
After the self-test the battery level will be displayed. A full charge will last for over 100 tests and printouts. If the battery is low you should recharge the analyzer. When the battery charge is low asterisks (*) flash in the middle of the screen. If you see this symbol the battery will have enough charge for about 10 tests and printouts. For more information, see charging your analyzer.

To monitor the battery charge level during operation press the COMP key on the analyzer's keypad. While the COMP screen is displayed, press the ENTER key repeatedly until you see the battery screen which displays the battery charge level.

Checking the Print Roll
The print roll will last about 100 printouts. Check the print roll by opening the paper roll access door or by pressing the FEED key on the analyzer's keypad. If a red stripe appears on the edge of the paper the paper is nearly depleted so be prepared to change the print roll. For more information see loading paper.

Note that when the analyzer is first turned on the DATA or TEST key must be pressed before the PRINT and FEED keys can activate the printer. This feature prevents the printer from turning on accidentally while the analyzer is in its carrying case.

Setting Units of Measurement
The analyzer can display units of measurement in either English or metric units. If you want to change the units of measurement press the UNITS key. The UNITS key acts as a toggle switch between English and metric units.   

Setting the Date and Time
Before the analyzer is shipped from the factory the time and date are preset to Pacific Time. To reset the time and date to your local time press the DATE key. Type in the date in numeric form and press ENTER after each entry. For example, type 11, ENTER, 17, ENTER, 16, ENTER for November 17, 2016.

Type in the time in a 24-hour format. For example, type 15, ENTER, 35, ENTER for 3:35 pm. Press the ENTER key after the hour and after the minute entry. You can change the time when daylight savings time occurs or when the unit is moved to another time zone. You may need to reset the time occasionally as the electronic clock may gain or lose a few minutes each month.

Selecting an International Language
If you purchased the international version of the analyzer you can specify the language the analyzer uses for its screens and printouts. To choose a language press the COMP key. While the COMP screen is displayed, press the ENTER key repeatedly until the language screen is displayed.

The > will point to the current language selected. To select another language, press the corresponding number (1 through 8) to change to the language you wish to use for displaying screens and printing reports. Press any other key to continue.

Entering Subject Data
Subject data must be entered prior to conducting a bioimpedance test. Press the DATA key on the analyzer keypad to access the subject data screen.

Press the ./MF key to indicate the gender of the subject. The ./MF key acts as a toggle switch between male and female.

Press the ENTER key to advance to the age field. Use the numeric keys to enter the subject's age in years.

Press the ENTER key to advance to the height field. Use the numeric keys to enter the subject's height in inches or centimeters.

Press the ENTER key to advance to the weight field. Use the numeric keys to enter the subject's weight in pounds or kilograms.

To return to the SEX field, press the ENTER key.

While entering subject data you have the option of specifying a subject's exercise activity. This feature is used to optimize test results for athletic subjects. To access this feature press the DATA key again. You will see the exercise screen. Enter the number of hours the subject exercises each week. An hour of exercise is defined as one hour of at least semicontinuous exercise. It does not mean one hour at the club, gym, or track. When you use this feature the analyzer will factor the exercise level of the subject into the test results. See calculations. If you do not use this feature the analyzer will use its normal equations for calculating mass distribution and water compartments.

Running a Test
Press the TEST key. To measure the subject press the TEST key again. The analyzer will measure the subject and calculate test results. After that, to print a report, press the PRINT key.

Or, you can input a bioresistance (R) value and use the analyzer to recalculate results. This is useful if you have made an error entering the subject data but realize this after you have disconnected the subject from the analyzer. You can use this feature to correct the subject data, reenter the bioresistance value from the previous measurement and recalculate the results, without reconnecting the subject.

Reviewing Test Results
Use this feature to review test results prior to printing a report. After a test is run the analyzer will display Percent Fat, Fat Weight, Lean Weight, and BMR. Press the COMP key to review the subjectís BMI. Press the COMP key repeatedly to toggle back and forth between the two screens.

To review water compartments press the TBW key. The analyzer will display Total Body Water in liters and Total Body Water as a percentage of lean body weight.

Press the OHMS key to display the measured Resistance (R) and Reactance (X).

Press the TARGET key to review the recommended Target Fat Percentage and Target Weight.
