The administrator is allowed to use all the functions and has all access rights. A user, on the other hand, is not allowed to use all the functions and has limited rights, see table 1 below. Tab. 1: Authorisation level Administrator Available rights and functions The administrator is allowed to use all the functions and has all access rights.
3 Basic instructions 3.1 Proper use The display unit acquired by you is used in combination with a load cell and serves to determine the weighing value of material to be weighed. It is not intended for use as non-automatic weighing system. 20 Place load manually but carefully on weighing platform. Prevent loads from dropping. Place load in centre. Prevent lateral stress as well as pushing from the side. As soon as a stable weighing value is reached the weighing value can be read.
3.2 Improper Use Do not use weighing system for dynamic weighing. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“ in the unit. (Example: Slowly draining fluids from a container on the balance.) Do not leave permanent load on the weighing pan. This may damage the measuring system.
4 Basic Safety Precautions 4.1 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.
