  • Page 2: Preface

    Thank you for purchasing an RL-TA Series electronic balance. The RL-TA Series is a new balance equipped with a high-precision tuning fork sensor mechanism. It windshield is made of antistatic plastic, helping to reduce its weight, and the balance is equipped with a variety of functions such as parts counting, percentage weighing, gravimeter and limit functions that are helpful in weighing fixed amounts.
