7.1 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. 8 Transport and storage 8.1 Testing upon acceptance When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
9 Unpacking, Setup and Commissioning 9.1 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: •...
9.3 Scope of delivery 9.3.1 MPE-HM and MPE-PM models • Balance • Power pack unit • Operating instructions 9.3.2 MPE-HEM and MPE-PEM models • Weighing scale with tripod • Batteries 6 x AA 1,5 V • Operating instructions 9.4 Balance assembly and installation Scope of delivery: Fig.
Page 15
Refitting Procedure: Mount tripod (1) on tripod holder (2) at weighing platform Ensure that the cable (3) does not get clamped! Fasten tripod, using 4 screws Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.
9.4.1 Installing the body height meter The force required to extend the telescopic body height meter may be adjusted using to adjustment bolts on the stand (see the figure). To do it, proceed as follows: Hide the whole body height meter completely in the stand.
The stated voltage value must be the same as the local voltage. Always use genuine approved KERN power pack units. The small sticker attached to the side of the display unit indicates the power port: The LED remains illuminated as long as the weighing scale remains connected to the mains.
9.6 Battery operation is possible by obtaining an optional battery power pack. Open the battery compartment cover (1) at the base of the display unit and insert the rechargeable battery. Charge the battery for at least 12 hours before initial use. The appearance of the symbol in the weight display indicates that the battery is almost exhausted.
9.7 Battery operation As an alternative to rechargeable battery operation, the balance may also be operated with 6x AA batteries. Open battery compartment cover (1) at the lower side of the display unit and insert batteries according to the example below. Lock the battery cover again. If the batteries are empty, in the balance display appears the symbol .
9.8 Installation of accumulator / battery exemplified by a battery set: Remove battery compartment cover Connect battery holder to housing contact acc. to illustration Insert battery holder Insert batteries into battery compartment and lock with battery compartment cover. 9.9 Initial Commissioning In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap.
10 Operation 10.1 Weighing Start balance by pressing The balance will carry out a self-test The scales are ready for operation as soon as the weight display for “0.0 kg“ has appeared. • However, you can reset the weighing scale to zero by pressing key.
10.2.1 Subsequent tare weight The balance can be tared several times successively. 10.3 HOLD function The balance has an integrated standstill function (mean value calculation). With this function it is possible to weigh people accurately even if they do not stand still on the weighing plate.
10.5 Calculation of the Body Mass Index You need to know a person’s body height before you can calculate the BMI for that person. It should either be known or can be determined directly with the MPE-HM and MPE-HEM model. 10.5.1 Measuring body height (MPE-HM and MPE-HEM only) ...
Read body height on measuring stick. 10.5.2 Calculating Body Mass Index Start balance by pressing Wait for stability display „STABLE” to appear. Press The most recently entered body height will be shown with the enable digit flashing. The „BMI“ symbol lights up. ...
• Reliable calculation of BMI is restricted to a body height of 100 cm to 200 cm and a weight of >10 kg. • If weighing has to take place under unsteady conditions, you can be stabilise the display by applying the Hold function. 10.5.3 Classification of BMI values Weight classification for adults over 18 years of age using the BMI in accordance with WHO, 2000 EK IV and WHO 2004.
10.6 Automatic switch-off function „AUTO OFF“ The weighing scale will switch off automatically after the allotted time as long as neither the display unit nor the weighing plate is operated. • Menu settings: [F1 oFF] [oFF 0/3/5/15/30] (see chap. 12) ...
