Basic Information (General)

Balances have to be verified for the purposes stated below in accordance with Directive 2014/31/EU. Article 1, paragraph 4. “Determination of mass in the practice of medicine that is, weighing patients for reasons of medical supervision during medical surveillance, examination and treatment.”

4.1 Specific function
4.1.1 Indication
• Determining the body weight in the medical practice area
• Using as „non-automatic balance“
➢ The person steps carefully on the center of the weighing platform.
Once a steady display value is shown, you can read the weight result.

4.1.2 Contraindication
No contraindication known.

4.2 Proper use
This weighing scale is designed for determining the weight of a person whilst standing, such as in medical treatment rooms. The regularly used function of the balance consists of recognizing, prevention and treatment of illnesses.
• On personal weighing scales, the person should step onto the center of the weighing platform and remain standing without moving.
Once a steady display value is shown, you can read the weight result. The weighing scale is designed for continuous duty.
The weighing platform may only be stepped on by persons capable of standing on both feet on the weighing platform.

• The weighing platforms are fitted with an anti-slip surface that must not be covered during weighing a person.
• The balance should be checked for correct condition prior to each utilization by a person familiar with proper operation of the balance.
• When using balances with mounted body height measuring rod, ensure that the top flap is turned downwards immediately after use in order to avoid risk of injury.
The WIFI interface allows a wireless transfer of the measurement results to a PC.
Scales fitted with a serial interface may only be connected to appliances in compliance with Directive EN60601-1.

If the balance doesn’t have any contact with the transfer cable, do not touch the transfer port in order to avoid an ESD-failure.

4.3 Non-intended product use / contraindications

• Do not use these scales for dynamic weighing processes.
• Do not leave permanent load on the weighing pan. This may damage the measuring system.
• Impacts and overloading exceeding the stated maximum load (max) of the weighing plate, minus a possibly existing tare load, must be strictly avoided. This could cause damage to the balance.
• Never operate the balance in explosive environment. The serial version is not explosion protected. It should be notedthat a flammable mixture of anaesthetics and oxygen or laughing gas may occur.
• The structure of the balance may not be modified. This may lead to incorrect weighing results, safety-related faults and destruction of the balance.
• The balance may only be used according to the described conditions. Other areas of use must be released by KERN in writing.
• If the balance is not used for a longer time, take out the batteries and store them separately. Leaking battery liquid could damage the balance.
• The balance may only be used for weighing persons. Persons who are heavier than the indicated maximum load, may not step onto the balance.

Non-intended use of the optional body height measuring rod

• The body height measuring rod may only be assembled as specified in the operating instructions.
• The structure of the body height measuring rod may not be modified. This may result in incorrect measuring results, safety-related defects as well as destruction.
• The body height measuring rod may only be used according to the described conditions. Other areas of use must be released by KERN in writing. For more details please see the user manuals of the body height measuring rod.

4.4 Warranty
Warranty claims shall be voided in case:
• Our conditions in the operation manual are ignored
• The appliance is used beyond the described uses
• The appliance is modified or opened
• Mechanical damage and damage caused by media, liquids,
• Natural wear and tear
• Improper installation or faulty electrical connection
• The measuring system is overloaded
• Dropping the balance

4.5 Monitoring of Test Resources
In the framework of quality assurance the measuring-related weighing properties of the balance and, if applicable, the testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type and scope of this test.
Information is available on KERN’s home page (www.kern-sohn.com) with regard to the monitoring of balance test substances and the test weights required for this. In KERN’s accredited DKD calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost.
For personal balances with body height measuring rods, we recommend a metrological examination of the accuracy of the body height measuring rod, however, this is not mandatory as the determination of human body height involves rather large, intrinsic inaccuracies.

4.6 Plausibility check
Please make sure that the measurement values computed by the appliance are plausible and are allocated to the respective patient, before storing and using the values for further purposes. This applies especially also for values transferred via interface.

4.7 Reporting serious incidents
All serious incidents appeared related to this product must be reported to the manufacturer and the responsible authority of the member state where the user and/or the patient are residents.
„Serious incident“ that means an incident which directly or indirectly had, could have or could have had one of the following consequences:
➢ the death of a patient, a user or another person,
➢ the temporary or permanent fatal deterioration of the health status of a patient, a user or other persons,
➢ a serious danger for public health.

Basic Safety Precautions

5.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances.

5.2 Personnel training
The medical staff must apply and follow the operating instructions for proper use and care of the product.
The balance must be set up via the interfaces and integrated into a network only by experienced administrators or hospital technicians. \

5.3 Preventing contamination
The prevention of cross-contamination (fungal skin infections,……) requires regular cleaning of the weighing platform. Recommendation: After any weighing procedure that could potentially result in contamination (e. g. after weighing that involves direct skin contact).

5.4 Preparation for use
• Check the personal balance for damage before any use
• Maintenance and reverification (in Germany MTK): The personal balance must be serviced and reverified at regular intervals.
• Do not use the appliance on slippery surfaces or in facilities with risk of vibration
• During installation the personal balance must be levelled
• If possible, the product must remain in its original packaging for transportation purpose. Should this not be possible, make sure that the product is protected against damage
• Step onto and leave the personal balance only when a qualified person is present.

Electromagnetic compatibility (EMC)

6.1 General hints
This device complies with the limits set for medical electrical devices of group 1, class B (as per EN 60601-1-2). The device is suitable for home healthcare and professional health institutes environments.

The installation and use of this electrical medical device requires special precautionary measures as outlined in the EMC information below.
Do not install the appliance near active surgical high-frequency devices and in radio-frequency-screened rooms of a ME system for magnetic resonance reproduction where high intensity of electro-magnetic interferences occurs.
Please avoid to operate the appliance beside or stacked on other devices, as this may cause incorrect measuring results. If such use should be required, this appliance and the other devices should be observed, in order to ensure that they work normally.
Using accessories, transformers and other cables than the specified ones or delivered by the manufacturer together with the appliance, could have as consequence reinforced electromagnetic radiation or reduced electromagnetic immunity to interference and by that way reduced functionability.
Portable radio-frequency communication equipment (including periphery as well as antenna cable and external antennae) should be placed from any part of the MPN (including the cables authorised by manufacturer) at a distance of at least 30 cm (12 inches). Otherwise the performance of the appliance could drop down.

Note: The emission characteristics of this appliance allow its use in industrial areas and in hospitals (CISPR 11 category A). If it is used in residential areas (where CISPR 11 category B normal is required), this appliance cannot ensure sufficient protection against radio-frequency-communication services. In order to obtain reasonable results, the user should apply measures for weakening the intensity, e.g. install the device in another site or re-align it.
Electromagnetic compatibility (EMC) describes a device’s ability to perform reliably within an electromagnetic environment without causing there inadmissible electromagnetic interference at the same time. Amongst other things, such disturbances may be transmitted by connecting cables or by the air.
Inadmissible interferences from the environment may result in wrong displays, inaccurate measured values or incorrect behaviour of the medical device. The performance regulation is less than ±1kg instable reading when measuring with evaluated weight capacity.
In the same way, the personal balance MPN in certain cases may cause such disturbances in other devices. To eliminate problems of that kind, we recommend you to take one or several of the measures listed below:
• Change the alignment or distance of the device to the source of EMI.
• Install or use the personal balance MPN at another location.
• Connect the personal balance MPN to another power source.
• For further questions please contact our customer services.

Disturbances may be caused by improper modification or add-ons to the device or not recommended accessories (such as power supply units or connecting cables). The manufacturer will not be responsible for these. Modifications may also result in a loss of authorisation relating to the use of the device.

Devices emitting high frequency signals (mobile telephones, radio transmitters, radio receivers) may cause interference in the medical device. For that reason do not use them near the medical device. Chapter 6.4 contains details about recommended minimum distances.

Unpacking, Installation and Commissioning

8.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
On the installation site observe the following:
• Place the balance on a stable, even surface
• Avoid extreme heat as well as temperature fluctuation caused by installing next
to a radiator or in the direct sunlight
• Protect the balance against direct draughts due to open windows and doors
• Avoid jarring during weighing
• Protect the balance against high humidity, vapors and dust
• Do not expose the device to extreme dampness for longer periods of time. Nonpermitted condensation (condensation of air humidity on the appliance) may
occur if a cold appliance is taken to a considerably warmer environment. In this
case, disconnect the appliance from mains and acclimatize it for approx. 2 hours
at room temperature.
• Avoid static charge of the balance and of the person to be weighed.
• Avoid contact with water.
Major display deviations (incorrect weighing results) may be experienced, should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity
accumulations or instable power supply occur. Change location or remove source of
interference.
8.2 Unpacking
Take the balance out of its packaging and place it at the intended position. When using
the power supply unit, ensure that the power cable does not produce any risk of
stumbling.
