3 Basic Information (General) Intended use This device allows medical staff to test a patient‟s fitness status and to carry out controlled training during the rehabilitation process. The appliance should be checked for correct condition prior to each utilisation by a person familiar with proper operation of the balance. Non-intended use Changes to the unit's design are not permitted. This may lead to incorrect measuring results, safety-related faults and destruction of the unit.
4 Basic Safety Precautions Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances. Versions in other languages are non-binding translations. The only binding version is the original document in German. Staff training The medical staff must apply and follow the operating instructions for proper use and care of the product.
6 Removing packaging and initial start-up Place of application The unit is designed to achieve reliable measuring results under normal conditions of use. Required conditions for place of operation: Prevent extreme heat and temperature fluctuations Protect the appliance against high humidity, vapours and dust; Do not expose the device to extreme dampness for longer periods of time.
How to replace a spring set [1] [1] 1. Press device until the two screws [1] become visible. 2. Remove screws. 3. Remove grip first, followed by springs. 4. Insert desired spring set. 5. Reassemble device in reverse order.
Install two additional washers only in the 130 kg-spring set. (s. fig.
Battery operation 1. Open battery cover, as shown on illustration. 2. Replace battery (CR-2450). 3. Reinsert the battery cover. To save battery power, the device auto-disconnects automatically after 60 seconds have passed without a change of display. If the batteries are run down soon, "LO" appears in the display. Replace battery. 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.

Turn on/off Zeroing Switch on the device by pressing the Zero display appears. /zero key. If the device does not exactly show zero, unload the device and press the /zero key. To switch off, keep seconds. /zero key pressed for approx. 3 During power-up the device will return to the mode or unit (kg/lb) it had been in before it was switched off.
7.1 Operating modes The device is in real mode at delivery. Use the mode key to switch over the device to the following operating modes. Operating mode Real time mode Display Function Shows current strength. Counting mode Counts number of gripping actions exceeding a previously set strength limit. Average mode Calculates the average strength derived from two hand grips Peak/Max Mode 20 Shows max strength of hand grip.
Real time mode 1. Show actual strength Relieve Press Release 2. Change unit kg lb In real mode it is possible to switch from “kg” to “lb” by pressing the set key – and vice versa. During power-up the device will return to the mode or unit it had been in before it was switched off.
Counting mode 1. Call mode Switch on the device by pressing the /zero key. Press mode key repeatedly until the count display appears. 2. How to define the strength limit The currently set strength limit is displayed. To change, press the mode key repeatedly until the desired strength limit is displayed. Ensure that the capacity of the spring is not exceeded (e. g. strength limit for 20 kg spring set < 20 kg). Confirm by pressing the set key; count display appears.
3. Counting gripping actions Press, and release device as often as possible. Each gripping action is acknowledged by an audio sound. The number of gripping actions carried out will be shown on screen. 4. Start further counting Press the /Zero button, the zero display disappears. Count gripping actions as described under item 3.
Average mode 1. Call mode Switch on the device by pressing the /zero key. Press mode key repeatedly until avg. display appears. 2. Determine average strength from two hand grips Carry out first gripping action Strength of first hand grip will be shown. Carry out second gripping action. Strength of second hand grip will be shown.
Press the set key; average strength derived from the two hand grips will be calculated and displayed flashing. 3. Start further measurements To return to measuring mode, press the set key. Press the /Zero button, the zero display disappears. Carry out further measurements as described under item 2.
Peak/Max-Mode 1. Call mode Switch on the device by pressing the /zero key. Press the mode key repeatedly until max display appears. 2. Carrying Out Measurement Example: Example: A gripping action achieves a strength of 50 kg. Now you are able to determine whether follow-up measurements also reach 50 kg = 100% or for example only 31% = 15.5 kg (adjustable range 1-100 %) Carry out gripping action The strength of the first hand grip will be displayed and can be stored by pressing the set key.
To change, press the mode key repeatedly until the desired percentage appears. Use the Set key to confirm. If a new gripping action shows a strength of less than for instance < 31 % (< 15.5 kg), the previous max value will be retained. If a new gripping action shows a strength greater than for instance > 31 % (> 15.5 kg), the new max value will be displayed. The previous max value will be overwritten with the new value.
8 Service, maintenance, disposal Cleaning Service, maintenance Disposal 28 Please do not use aggressive detergents (solvents etc.). Apply soapy water to moist cloth or use household detergent. Prevent fluid from penetrating into device. Finish by polishing with dry soft cloth. Remove dirt immediately. The appliance may only be opened by trained service technicians who are authorized by KERN.
9 Error messages Capacity of batteries exhausted. For replacing of batteries, see chapter. 7 Underload, set to zero by pressing /zero key Overload, release device Preload error, put minor stress on device during power-up EEPROM error, switch-off and restart device. If the error message remains inform manufacturer.
