1. INTRODUCTION
This manual describes how the AD-1691 Weighing Environment Analyzer works and how to get the most
out of it in terms of performance.
Read this manual thoroughly before using the analyzer and keep it at hand for future reference.
1-1. Features
The AD-1691 Weighing Environment Analyzer is a tool to support various functions such as daily
balance checks, uncertainty calculations and evaluations of the environment where the balance is
installed.
The 7-inch color LCD with a pressure sensitive touch panel provides excellent visibility and
operability.
The AD-1691, being compact in size, can be carried to the balance installation site easily.
One analyzer can manage several balances.
Using the AD-1691, daily and periodic balance checks will become easier.
The results of the checks can be output to a USB memory as a PDF file or can be output directly to a
printer.
→Daily balance check ..............................Page 8
→Periodic balance check .........................Page 19
Uncertainty can be calculated only by connecting the AD-1691 to a balance and entering the data in
the screen.
At the balance installation site, the calibration results with the uncertainty data can be output as a PDF
file and can be saved in a USB memory.
→Uncertainty calculation ..........................Page 35
The AD-1691 displays the balance measurement data in real time and allows operating the balance
keys.
The AD-1691, when used as a balance remote controller, enables the weighing operation without
touching the balance, minimizing external disturbances caused by the balance operation.
→Balance remote controller .....................Page 33
The AD-1691 displays the AND-MEET data as a graph to evaluate the environment where a BM
series analytical balance is installed and outputs the results to a USB memory as a PDF file.

6. PERIODIC BALANCE CHECK
Touch [Periodic balance check] in the HOME screen to open the Periodic check screen.
In a periodic check, a weight is used to inspect the basic balance performance such as repeatability,
linearity and eccentricity error and check the measurement value against the specifications.
How to perform a periodic check depends on the balance management level. It is recommended that a
periodic check be performed once a week or a month.
