1. Place the balance on a solid surface to ensure stability. Operate the balance in a room where
the temperature ranges between 10 - 40o C (50 - 104o F).
2. The balance must be positioned away from heat sources, magnetic fields, vibrations, and air
drafts to receive stable and repeatable results. Balance is to not to be used for explosive
materials.

3. Prior to switching the balance on, let it reach room temperature (estimated stabilization
time: 1 - 8 hours).
4. Connect the adapter cable (DB9-M) to the rear of the scale. During this process there should
be no load on the weighing pan.
