14  Important Information 

 
These electronic balances are precision instruments. It is designed for use in a self-
controlled electromagnetic environment. That means that in such an environment 
radio equipment, such as mobile phones, must not be used in direct vicinity. In case 
strong electromagnetic fields should arise, deviations of the indication are possible. 
Avoid disturbing environmental conditions such as currents and vibrations as well as 
a rapid change of the ambient temperature. If necessary readjust the balance after a 
change of temperature. 
 
Avoid high humidity, vapours and dust as the balance is not hermetically closed. Do 
not let the balance come into direct contact with liquids as these could enter the 
measuring cell. Therefore only clean the balance with a dry or damp cloth. Do not 
use solvents as varnished or plastic parts could be damaged. 
 
A warming up time of a few minutes after switching the balance on will stabilise the 
measuring values. Place the object carefully on the weighing pan. Avoid any constant 
load on the weighing pan even when out of use. Avoid shocks, thrusts and extreme 
impairments by all means. Remove spillages immediately. 
 
When the programme cycle is disturbed switch the balance off and then on again. 
Start the weighing operation again. 
 
Never use the balance in rooms where there is a danger of explosion. The serial 
version is not explosion-proof. 
 
The balance should be adjusted regularly with the given adjusting weight. 
 
Keep the packing materials for any possible reshipment. When reshipping, use only 
the original packing materials. 
 

Opening of the balance causes invalidity of warranty.
