（日本語の取扱説明書は反対面をご覧ください。）
1. Introduction
The AD-8920 is a remote display that uses vacuum fluorescent display technology. It displays the weighing
data transmitted by an A&D manufactured weighing instrument using RS-232C or current loop. Applicable
weighing instruments (electronic balances/platform scales) are listed below. When the output connector of the
weighing instrument is of the DIN type, an optional DIN conversion cable is required.
