1.2 Descriptions
The purpose of this manual is to help the user get to know the indicator’s various weighing modes,
keys’ functions and display indications.
In addition to having all the characteristics of a high precision scale, the indicator has weight unit in kg
and lb, gross and net weighing, manual and automatic weight accumulation with serial output, counting
functions and 4 set points. The indicator is applicable in either industrial settings or legal for trade
applications. It provides the frequently needed ability to transmit and print the data through its serial
ports.
Please carefully follow the instructions to configure the indicator. By taking actions not
indicated this manual, one could cause the indicator to not work properly.

AUt=3, dynamic weighing method. At weighing >20d: the buzzer sounds
“du” and lock is displayed for 6 seconds. When a new data is fixed, lock
is displayed again for 6 seconds. Then lock is released for weighing
<20d; automatic accumulation and print. Suggest FLt>30, 〖AUTO〗is
on.
AUt=4, peak value fixed weighing method. At weighing>20d, the buzzer
sounds “du” and lock is displayed. When weighing <20d, fixed data
displays with flash, automatic accumulation and print. Lock can be
