Cleaning#

Always keep the cabinet clean to ensure proper use and to avoid potential cross-contaminations.

For cleaning, use the antistatic decontamination wipes present next to the weighing cabinet.

How to turn on the safety cabinet#

• Upon activation, the unit checks both left and right-hand sensors, displaying their status (e.g., “LEFT OK”).
• If a fault is detected, the display will indicate the sensor name and “faulty” until the fault is cleared.
• Wait for successful completion of memory test and initialization before proceeding.
