Initial Setup and Operating Procedure

3.1  Notes Before Starting Measurement

Have you read and understood the Operating Instructions, in particular 
Chapter 1 “Basic Safety Notices” ?
You are not permitted to operate the tension meter before doing so.
Before working with the instrument you must put on your personal protective 
clothing, if necessary. For example, eye protectors, gloves, etc.
To avoid damage, do not move the rollers by hand.

Tensions that exceed the tension range of the instrument by more than 100% 
may cause permanent damage to the measuring spring and must be avoided 
under any circumstances. 

2.3  Unpacking

Unpack the tension meter and inspect it for any shipping damage.
Notices of defect must be filed immediately, at the latest within 10 days on receipt of the 
goods.
