CAUTION AND WARNING
To prevent injury and damage to your scale, please follow these instructions very carefully.
• For accurate weighing the scale must be placed on a flat and a stable surface, locking screw
is locked properly and the scale bottom is not touching the floor.
• For accurate weighing, verify proper operation according to the procedure described in this
manual before each use.
• Do not use in the presence of flammable materials.
• Operating at other voltages and frequencies than specified could damage the equipment.
• If the “LOW BAT” indicator activates, for accurate weighing, replace the batteries or connect
the scale to an AC power source as soon as possible.
SPECIFICATIONS
GENERAL
Health o meter’s Pro PlusTM Portable Wheelchair Scale Model 2450KL uses highly sophisticated
microprocessor technology. Each precision instrument is designed to provide accurate, reliable
and repeatable weight measurements and features that make the weighing process simple, fast
and convenient.
The scale is set up to use motion-sensing weighing technology, to determine the actual weight
of a moving patient. The scale may be changed to measure live weight; see page 13 for
instructions on changing the scale setting.
The weight can be display in pounds (decimals, fractions of a lb or lb/oz) or in kilograms. The
scale features low self-weight, width-adjustment mechanism to fit wheelchair various dimensions
and a display assembly stand.
The unit can be operated using its AC adapter or by 6-D cell batteries (not included).

OPERATION INSTRUCTIONS
02 TARE WEIGHT
NOTE:Due to the scale’s sensitivity, we recommend using the REWEIGH function prior to
setting the TARE weight, in order to eliminate any operator interference with the item to
be tared out.
There are two ways to manually enter a tare weight (such as the weight of a wheelchair, shoes,
etc): press MENU (1) and select option 02-Tare Weight or press TARE (9). If there is no weight
on the scale platform (value displayed is zero and there is no tare) and the user presses the
TARE button (9), the Tare Weight window appears and prompts the user to enter the TARE
value and to press ENTER. NOTE: The tare weight must be entered using the following
increments: 4oz, 0.2lb, ¼lb. The value entered will display in minus (-). After the TARE has been
entered, the scale goes back to normal operation. This TARE value is stored in memory until
changed or cleared.
Important: The TARE weight cannot exceed 125 lb.
TARE display
indicates the weight
that has been tared
out
The number that is to be changed will
flash and will move from the left to the
right after the appropriate number was
entered or by using the ckey (left)
and the dkey (right).
Figure 8. Tare Weight
Automatic Tare
The user can set a tare weight by pressing the TARE button (9) while there is a weight on the
scale platform. The display will come to zero and TARE will be displayed to indicate there is a
tare value in the memory (as displayed in Figure 8 above).
Removing the Tare
Additional pressing of the TARE button will delete the tare value from memory, TARE will
disappear from the display and the scale will resume normal operation.
03 DATA MANAGEMENT
The scale manages patient data including patient ID, weight, height, tare and BMI. The value is
stored in memory or transferred to PC. This function is performed by opening a new data file.
OPENING A NEW DATA FILE:
1. Press the ID button (7).
2. Using the keypad, type in the identification number.
3. Press ENTER.
This scale will also calculate Body Mass Index (BMI).
CALCULATING BMI:
1. Place the patient on the scale platform.
2. Press the BMI button (2).

10
OPERATION INSTRUCTIONS
3. The scale will prompt you to enter the patient’s height. Use the keypad to enter the height in
1/4" (1=1/4, 2=1/2, 3=3/4) or 1 cm increments (use inches for weight in lb, cm for kg). Press
ENTER.
4. Display will read the patient’s BMI.
The scale offers you two options to manage your information: to transfer/download the values or
to store them. The first option automatically downloads (transfers) the value to your PC. The
second option stores the value in memory. The maximum capacity of the scale is 270 files of
different data.
01 Auto Download
Automatic Download is the default option and will transfer the
value to the PC as soon as the patient steps off the scale or
when the user presses the HOLD/RELEASE button if it was
kept in “HOLD”. If no PC is connected, the value is not
transferred and not stored and will be lost after the load is
removed from the scale.
02 Store in memory
The value is stored in memory
for later download to PC.
If the memory is close to full
the user will be warned and
given the option to transfer all
values to the PC or to clear
the memory of all values.
03 Do not store data
All the data will be cleared.

11
OPERATION INSTRUCTIONS
04 Transfer now
All the values stored in memory are transferred to the PC and
the scale memory is cleared of all values. If the transfer was
unsuccessful, the values are kept in memory until
successfully transferred or cleared.
05 Clear memory
All the values stored in memory will be cleared.
04 SCALE SETTINGS
01 Auto Hold Time
The user can determine how long to display the weight
reading once it is determined, regardless of whether the
patient remains on the platform. The scale defaults to no Auto
Hold Time. The maximum setting is 20 seconds Hold Time.
02 Sleep Time
The user can set the time elapsed before the scale goes into
the sleep mode. The default is 1 minute. When the scale
goes into sleep mode, STANDBY is displayed on the screen.

before turning off automatically due to inactivity. Default
time is 10 minutes. If the value is set to zero, the auto off
function is disabled.
04 Tone Volume
There is an option to adjust the beeping tone of the scale.
This tone should sound when the scale has determined
the weight on the platform, when a key is pressed, after
the scale is turned on, at the end of self-test, or in the case
of fault or warning.
Use the cand dkeys on the keypad to adjust the
volume.
Whenever the user presses the key to change a volume, a
beep will sound to indicate the set volume level.

movement; the scale will not lock on quickly to the weight
as is the case in the motion-sensing mode.
Press the REWEIGH button to operate the motion-sensing
mode and to determine the correct weight on the screen.
To revert back to motion-sensing mode, change the Live
Weight setting to “No”.

06 SYSTEM TEST
01 Battery Test
The scale will display the estimated amount of battery life
remaining until the batteries will have to be replaced.
NOTE:In order to complete the battery test, the scale must be
powered by batteries only. Unplug the scale from AC power
source prior to battery test.
02 USB Connection
The scale will test the connection to the PC and will display a
message “Connection is OK” or ”NO Connection”.
If “NO Connection” is displayed, check your USB connections
on the scale and on your PC and retest the connection. Refer
to qualified service personnel if problem persists.

15
OPERATION INSTRUCTIONS
03 UI Test
The scale has a diagnostic routine where it tests the User
Interface (UI) hardware functionality (LCD, keypad). In order to
do this the user has to press all the keys according to the
messages displayed on the screen.
If the requested command was not received or wrong button
was pressed, the following message will be displayed.
If after 10 seconds the requested command was not received,
the following message will be displayed. If “UI Error Failure” is
displayed, refer to qualified service personnel.
07 USER SETTINGS
01 Retain Entered Values
This option allows the user to use the same values for ID,
height and TARE between weighing. If this option is disabled,
the user has to re-enter these values for each reading. If the
values are not entered, only the weight is stored.
NOTE: These values cannot be retained by ID number.

16
OPERATION INSTRUCTIONS
02 Disp Height & ID
When the user selects to
display the height and ID of the
user, it will be displayed at the
bottom of the screen. We
recommend the use of this
function to ensure that the
patient’s correct ID and height
have been entered.
03 Prompt For Height
When this option is activated,
the user will be asked to enter
the patient’s height after every
weighing.
04 Prompt For ID
When this option is activated,
the user will be asked to enter
the patient’s ID number after
