General Safety

Do not operate or work on this equipment unless this manual has been read and all instructions are understood. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Rice Lake Weighing Systems dealer for replacement manuals.

WARNING: Failure to heed could result in serious injury or death.

Do not use in the presence of flammable materials.
Operating at other voltages and frequencies than specified could damage the equipment. Use only medical approved mains adapters compliant with EN60601-1 standard.

Do not modify this equipment without authorization of the manufacturer.
Do not put this equipment next to or stacked on top of other equipment. This may result in malfunction. If such placement is unavoidable, ensure equipment is monitored regularly for correct operation.
Do not use accessories, transducers or cables other than those specified or provided by manufacturer. This could result in increased electromagnetic emissions or decreased electromagnetic immunity leading resulting in malfunction (see Section 6.0 on page 20).
Portable RF communications accessories (including peripherals such as antenna cables and external antennas) should be used no closer than 30 mm to the equipment or cables specified by the manufacturer. This may result in equipment performance degradation (see Section 6.0 on page 20).

Ensure the equipment is located in a shielded location. Failure to do so may result in performance degradation, interference with other equipment or interference with radio services.
This equipment has been tested for radiated RF immunity at selected frequencies. Using this equipment near equipment emitting other frequencies could result in improper operation (see Section 6.0 on page 20).

CAUTION: To prevent injury, never leave the person being weighed unattended while on the scale.
To prevent injury, do not transport the scale while a patient is on the scale.
Make sure no load is on the scale before transporting the scale.
Do not drop the scale or subject it to violent shocks.
The scales are for determining weight of persons in rooms intended for carrying out medical care. The scales are NOT intended to diagnose, prevent and monitor diseases. The scales are equipped with serial interface that can connect to the equipment compliant with EN60601-1 standard.

Do not use scale for dynamic weighing.
Do not leave a permanent load on the weighing plate. This can damage the scale.
Be careful to avoid shock and overloading the scale in excess of the prescribed maximum load rating (MAX) minus any tare weight that is already present.
Never operate the scale in a hazardous location.
The scale design is not explosion-proof. Flammable mixture can form from anesthetic means containing oxygen or nitrous oxide (laughing gas).

IMPORTANT: For accurate weighing, the scale must be placed on a flat, stable surface.
For accurate weighing, verify proper operation according to the procedure described in this manual before each use.
If the “LO Bat” indicator activates, for accurate weighing, recharge the battery or connect the scale to an AC power source as soon as possible.
To avoid cross-contamination, clean the scale plate after each weighing. Avoid direct skin contact during weighing.
The H151-11-8 is not equipped with the function of rechargeable battery.
The purpose of this scale is to determine weight in the course of medical practice.
Used as non-automatic scale, a person is to be positioned in the center of the scale plate. Weight can be read after stable value has been obtained.
Materials in the products have been tested and approved for the safe use by operator and patient.
All batteries included with Healthweigh products intended for sale in the EU market are classified as ‘Portable Batteries for General Use’ and comply with European Battery Regulation (EU) 2023/1542.

Communication
The scale has a communication protocol: ESC protocol. An ESC protocol is using the escape (0X1B or ASCII 27) to indicate that there is a command following. On the computer, side there must be a listener created by the vendor that will interpret this protocol. This listener must also take care of all the issues regarding data integrity, etc., to make sure that the data sent and received is valid.

Communication can be execute through either RS232 I/O port or USB I/O port. The communication parameters are:

• 9600 baud (selectable in the programming mode)
• 8 data bits
• 1 stop bit
• No parity
• No handshaking

For the USB connection, the USB driver installation will be on Windows® systems. The USB driver can be downloaded from the distributor and installation will be with the distributor’s guidance. The scale support EMR protocol, for addition information contact distributor.

Print Button
A long press will send data from both RS232 and USB ports. When data is transmitted out via a port the display flashes the word PRINT to acknowledge the data was sent.

In weight mode
PATIENT WEIGHT 60.1 kg

In BMI (On calculated BMI display only)
For kg Unit of Measurement:
