About Health O Meter

Health O Meter is a well-known brand that produces a wide range of healthcare and wellness products, primarily focused on measuring and monitoring personal health metrics. The company has a long history dating back to the early 20th century and is known for its scales, which are commonly used in both medical and home settings for tracking weight. Health O Meter’s products are designed to help individuals and healthcare professionals keep tabs on various health parameters, promoting a healthier lifestyle and aiding in medical assessments.



This Health o meter Professional wheelchair scale is intended to be used in a professional medical environment by trained medical staff. This product was designed to weigh patients who are safely seated in a wheelchair or standing on the platform. Do not modify the product or use it for anything other than its intended purpose.

To prevent patient/caregiver injury or damage to your scale, please follow the instructions in this user manual very carefully.

  • Do not exceed the weight capacity specified for this scale.
  • For accurate weighing, this scale must be placed on a flat, stable surface.
  • For accurate weighing, verify before each use the proper operation according to the procedure described in this manual.
  • Do not use it in the presence of flammable or explosive materials.
  • If the scale becomes damaged, it should not be operated until properly serviced.
  • Do not transport the scale with a patient or object on the scale.
  • To prevent injury and damage to your scale, do not drop or mishandle the scale, during use or transport.
  • Ensure that the AC adapter and scale do not come in contact with liquids, excessive temperature, or excessive humidity.

Patient/caregiver safety

  • This scale is designed for static weighing of patients only. No scale should be used for patient transfer.
  • To prevent patient injury, the patient must be attended throughout the weighing event.
  • Ensure the ramp and platform are kept clean and dry. Exercise caution when rolling the wheelchair onto and off of the scale.

When operating the scale with the AC adapter:

  • Operate this scale exclusively with the AC adapter that is provided (ADPT30). Use of an unspecified adapter will void the warranty and can pose a serious safety hazard.
  • Before using this scale, inspect the AC adapter cord for cracking / fraying, or for broken/bent plug prongs.
  • Before using this scale, ensure that the AC adapter is plugged into an outlet with the rated voltage appropriate for operation.
  • Ensure that the AC adapter outlet is wired to a circuit breaker or other protected power source.
  • Unplug the AC adapter, and carefully store both the adapter and adapter cord before moving the scale.
  • Operating this scale at voltages and frequencies other than specified can damage the equipment and will void the warranty.

When operating the scale with batteries:

  • If the scale’s battery icon indicates that the batteries are low replace the batteries or switch to the AC adapter as soon as possible.
  • When replacing/inserting batteries, be sure to use all new batteries.

This equipment has been tested and found to comply with the MC limits for the Medical Device Directive 93/42/EEC (EN 55011 Class A and EN 60601-1-2). These limits are designed to provide reasonable protection against harmful interference in a typical medical installation. The equipment generates, uses, and may radiate radio frequency energy and, if not installed and used by these instructions, may cause harmful interference to other devices in the vicinity. There is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference with other devices, which can be determined by turning the equipment off and on, the user is encouraged to try to eliminate the interference by one or more of the following measures:

  • Reorient or relocate the receiving device.
  • Increase the separation between the equipment.
  • Connect the equipment to an outlet on a circuit different from that to which the other device(s) is connected.
  • Consult Customer Service or a field service technician for help.



This scale uses highly sophisticated microprocessor technology. Each precision scale is designed to provide accurate, reliable, and repeatable weight measurements. In addition, each scale is designed to provide the user with features that make the weighing process simple, fast, and convenient. This scale uses motion-sensing weighing technology to determine a moving patient’s actual weight.

The 2500KL displays weight in pounds (lb) or kilograms (kg). Refer to Page 11 to learn more about configuring the weight-measuring unit setting. The 2500 kg displays weight in kilograms only. This scale features a pivoting display head for privacy and easy operator reading. For easy mobility, the scale has 2 built-in wheels. Each scale can be powered using an AC adapter (ADPT30 included) or by 6 D batteries (not included).


Scale information can be found by pressing Help and selecting “Scale Info” in the submenu. This screen provides model number, capacity, calibration weight, the most recent field calibration date, number of field calibrations, and software version.

Parent/Child Function

The Parent/Child function on Health o meter® Professional scales provides the convenience of weighing a small child or infant while being held by a parent. Follow these simple steps to subtract the parent’s weight from the total so only the child’s weight is displayed.

  2. Ask the parent to step onto the scale without the child. The display will show a value for the parent’s weight.
  3. With the parent remaining on the scale press J. The scale will be zero, and the word “TARE” will appear at the bottom center of the display along with the parent’s tared weight.
  4. Carefully place the child into the parent’s arms. The scale will automatically deduct the weight of the parent and only display the child’s weight.
    Note: For an alternate method, after taking the parent’s weight in step 3, have the parent step off of the scale. With no weight on the scale, the display will show the tare value as a negative amount. Have the parent step back onto the scale while holding the child. The scale will automatically deduct the weight of the parent and only display the child’s weight.
  5. The tare value will remain on the display until changed, cleared, or until the scale is powered off. To remove the Tare, press Tare. The word “TARE” will disappear from the bottom of the display, and the tare value will be cleared from the display. The scale will resume normal operation.

This scale has been factory-calibrated and does not require calibration before use. There are no requirements for calibration in the field; users should adhere to their institution’s calibration policies.

Calibration of your scale can be performed using calibrated kilogram (kg) or pound (Ib) weight standards. The minimum calibration is 200 lb / 100 kg. Maximum calibration weight is 1000 lb / 454 kg. The required calibration standard will be the Unit of Measure (UOM) for which the scale is configured. KG models can only be calibrated in kilograms. If Everlock® is engaged the scale can only be calibrated in the locked unit of measure. Note: Only weights certified and traceable to national standards should be used for calibration.

Always ensure that the scale is returned to the correct UOM after scale calibration.
