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.

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

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.
