4 Basic Information (General)

4.1 Proper use

These scales are used to determine weight of people sitting at rest, The person to be weighed should carefully sit down on the center of the seat and remain seated quietly.

As soon as a stable weighing value is reached, the weighing value can be read. The balances are designed for long-term usage.

Determination of the body weight.

Use as „non-standalone weighing scale“, that is, a person sits carefully onto the seating surface’s centre. Once a steady display value is shown, you can read the weight value.

The balances shall only be used by people who can sit still.

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.

The balances should be checked for correct condition prior to each utilisation by a person familiar with proper operation of the balance.

4.2 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 overload 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 balance in explosive environment. The serial version is not explosion protected. It should be noted that 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.

4.3 Warranty

Warranty claims shall be voided in case:

• Our conditions in the operation manual are ignored
• The appliance is used outside the described uses
• The appliance is modified or opened
• Mechanical damage and damage caused by media, liquids,
  • Natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
• Dropping the balance

4.4 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.

4.5 Plausibility check

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

7 Unpacking, Installation and Commissioning

7.1 Place of installation / place of operation

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, vapours and dust
• Do not expose the device to extreme dampness for longer periods of time. Non-permitted 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. In that case, the location must be changed.

7.2 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.

10 Communication with peripheral devices via KUP connection

Via the interfaces weighing data may be exchanged with connected peripheral devices.

Issue may be made to a printer, PC or check displays. In reverse order, control orders and data inputs may be made via the connected devices.

The balances of the TMCN series are equipped with a KUP connection (KERN Universal Port) as per standard.

The following options are available as interfaces:

	Interface adapter with cable
	Model	Example for application
RS232	YKUP-01	Serial printer
USB	YKUP-03	PC
Ethernet	YKUP-04	PC
Bluetooth	YKUP-06	Android terminal unit or PC
Kern Extension Box	YKUP-13	Several interfaces in parallel

i

The available interfaces can be used via the KUP (YKUP-13) in parallel manner.

Connector assignment balance:

5 4 3 2 1 10 9 8 7 6 15 14 13 12 11

Warning: Only for use with KUP interfaces

Max. length of externally attached cables on the KUP interface: 10 m.

10.1 KERN Communications Protocol (KERN Interface Protocol)

KCP is a standardized set of interface orders for KERN balances, which allows many parameters and device functions to be called up and controlled. KERN devices that have KCP can use it to connect easily to computers, industrial control systems and other digital systems. A detailed description you will find in the „KERN

Communications Protocol" manual, available in the download area on our KERN homepage (www.kern-sohn.com).

To activate KCP please observe the menu overview of your balance's operating instructions.

KCP is based on simple ASCII orders and replies. Every interaction consists of an order, possibly with arguments separated by spaces and finished by . The KCP orders supported by your balance may be queried emitting the order „10“ followed by CR LF.

Extract of the mostly used KCP orders:

I0	Shows all implemented KCP orders
S	Sending stable value
SI	Sending current value (also instable)
SIR	Sending current value (also instable) and repeating
T	Taring
Z	Zeroing

Example:

Order	S
Possible replies	S__100.00_ S_ S_+ or S_-	Order accepted, execution of the order started, currently another order is executed, timeout reached, over- or underload

14 Servicing, maintenance, disposal

14.1 Cleaning

Before any maintenance, cleaning and repair work disconnect the appliance from the operating voltage.

14.2 Cleaning / disinfecting

Clean weighing platform (such as seat) as well as casing with household detergents or commercially available disinfectants, e.g. 70% isopropanol. We recommend a disinfectant suitable for wiping disinfection. Please follow manufacturer's instructions.

Do not use abrasive or aggressive cleaners such as spirits or alcohol or similar as they might damage the high-quality surface.

To prevent cross-contamination (fungal skin infection) please observe the following time intervals for disinfection:

• Weighing plate before and after any measurement with direct skin contact
• When required:

○ Display

- Touch-sensitive keyboard

Do not spray the device with disinfectant, just wipe it.

Make sure that disinfectant does not penetrate the interior of the balance.

Remove dirt immediately.

14.3 Sterilisation

Sterilisation of the appliance not allowed.

14.4 Servicing, maintenance

The appliance may only be opened by trained service technicians who are authorized by KERN.

We recommend a regular safety-related technical check (STK).

Disconnect scales from mains before opening.

14.5 Disposal

Disposal of packaging and appliance must be carried out by operator according to valid national or regional law of the location where the appliance is used.

15 Instant help for troubleshooting

In case of a fault in the program sequence, the balance should be shortly switched off. The weighing process must then be restarted from the beginning.

Fault:

The weight display does not glow.

Possible causes:

• The balance is not switched on
- The mains supply connection has been interrupted (mains cable not plugged in/faulty).
• Power supply interrupted.
- Rechargeable battery inserted incorrectly or empty
- No rechargeable battery inserted

The displayed weight is permanently changing

• Draught/air movement
• Table/floor vibrations
• The seating surface is in contact with foreign bodies or is not correctly positioned.
• Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

The weighing result is obviously incorrect

• The display of the balance is not at zero
- Adjustment is no longer correct
• Great fluctuations in temperature
- The balance is on an uneven surface
- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

No data can be transferred to the WIFI interface

• The mains signal is not stable or too weak
• Wrong interface configuration

Should other error messages occur, switch balance off and then on again. If the error message remains inform manufacturer.

16 Adjustment

As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the weighing system has not already been adjusted to the location in the factory). This adjustment process must be carried out for the first commissioning, after each change of location as well as in case of fluctuating environment temperature. To receive accurate measuring values it is also recommended to adjust the display unit periodically in weighing operation.

• Prepare the required adjustment weight. The adjustment weight to be applied depends on the capacity of a weighing scale, see chap. 1. Carry out adjustment as closely as possible to admissible maximum load of weighing scale. Info about test weights can be found on the Internet at: http://www.kern-sohn.com.
• Observe stable environmental conditions. For warm-up time required for stabilisation see chap.1.

Procedure:

	⇒ In weighing modeActuate adjustment switch. The service menu is called up. The first menu item “X10“ appears.
	⇒ Press the next menu item “AdJuSt” appears
	⇒ Confirm by, cALEXt is displayed.
	⇒ Press (again), „CALEXt“ is displayed.(should this not be displayed, press repeated) until „CALEXt“ is displayed
	⇒ Press the required adjustment weight is shown⇒ Acknowledge by, 7→“ is shortly displayed:Ensure that there are no objects on the weighing plate.
	⇒ „PutLd“ is displayed. During this display place the required adjustment weight on the weighing surface
	⇒ Press „eVLD“ is displayed. Remove the adjustment weight.The balance changes automatically into the weighing mode, the adjustment is concluded now.

An adjusting error or incorrect adjustment weight will generate an error message („WronG“), repeat the adjustment process.
