The Mettler-Toledo PL-L series electronic balance is a portable balance with a readability of 0.01g to 1g and a weighing range from 210g to 6.1kg. In addition to the basic operations of weighing, de-skinning, and adjusting and calibrating the balance, the balance also has various additional functions such as “recalling the weighing value”, “counting the weighing” and “percentage weighing”.
This manual provides step‑by‑step instructions for the PL‑L series electronic balances, including initial familiarisation, safety guidelines, installation, level adjustment, and hanging‑type weighing preparation. Detailed procedures for weighing, tare, quick weighing, percentage weighing, piece counting and unit conversion are described.
Technical information such as the RS‑232C interface, MT‑SICS command set, optional accessories, dimensions, power requirements and maintenance procedures are also included, along with troubleshooting and service guidance. This manual is written in Chinese.
