Press the RE-ZEROpossible errors.

key before each weighing to prevent

Calibrate the balance periodically so as to eliminate possible errors.

Take into consideration the affect of air buoyancy on a sample when more accuracy is required.

Avoid foreign matter (dust, liquid or metal fragments) that could get inside the balance.

Operate your balance gently. Shorten the operation time as much as possible ( Opening and closing door, putting and removing sample). Use a pair of tweezers (pincette) to avoid temperature changes due to heat from inserting your hand into the weighing chamber.

3.3.After Use

Avoid mechanical shock to your balance.

Do not disassemble the balance. Contact your local A&D dealer if your balance needs service or repair.

Do not use solvents to clean the balance. For best cleaning, wipe with a dry lint free cloth or a lint free cloth that is moistened with warm water and a mild detergent.

Avoid foreign matter (dust, liquid or metal fragments) that could get inside the balance.

3.4.Power Supply

Do not remove the AC adapter while the internal mass is in motion, for example, right after the AC adapter is connected, or during calibration using the internal mass.

If the AC adapter is removed under the conditions described above, the internal mass will be left unsecured, that may cause mechanical damage when the balance is moved. Before removing the AC adapter, press the ON:OFF key and confirm that zero is displayed in weighing mode.

When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on. This is a normal state and does not harm the balance. For accurate weighing, we recommend that you always plug in your balance so it can warm up.
