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.

8. UNCERTAINTY CALCULATION
Expanded uncertainty is calculated and the calibration results with the expanded uncertainty can be
recorded at the balance installation site. The calibration results are saved in a USB memory as a PDF file
and can be managed or printed via a personal computer.
What is uncertainty
To express the reliability of the value obtained by weighing or measurement, “accuracy” or “error” has
been used. However, to define “error” quantitatively is very hard. Therefore, “uncertainty” is used to
quantify in terms of probability and indicates the estimate value to show the range where the true value
exists.
Uncertainty does not indicate “error” which means the difference from the true value. It indicates the range
of variation where the true value exists.

The combined standard uncertainty is obtained by calculating the square root of the sum of the squared
values of each standard uncertainty.
The expanded uncertainty (U) is obtained by multiplying the combined standard uncertainty by a
coverage factor (k). For example, by two when the coverage factor (k) is 2 (95% confidence level).

9. AND-MEET ANALYSIS
AND-MEET Measurement Environment Evaluation Tool
High-sensitivity analytical balances detect minute environmental changes that users cannot detect. This
causes the measurement value to be unstable. This is especially so with the BM-20/22, a microbalance
with a minimum display of 1μg or a semi-microbalance of a minimum display of 10μg. Using these
balances, the specified repeatability may not be obtained in many cases, depending on the environment
where the balances are installed.
To help evaluate the environment wh ere a balance is installed, we offer the AND-MEET Measurement
Environment Evaluation Tool.
AND-MEET constantly monitors the installation environment of the balance while simultaneously loading
and unloading the internal weight of the balance automatically over 24 hours. AND-MEET evaluates
temperature changes and the corresponding repeatability of measurement data over time.
The span value is calculated by subtracting the zero point value from the value obtained when the internal
weight is loaded on the balance. Then, the standard deviation of the ten consecutive span values is
calculated to obtain the repeatability. The result is presented as a graph for visualization.
Time is plotted on the X-axis of the graph. Changes in the zero point, span value, repeatability and
temperature are plotted on the Y-axis. Through the graph, interaction between each item (changes in the
zero point, span value or repeatability) and environmental changes (time and temperature) can be
evaluated.
The BM series balances are equipped with the AND-MEET function.

AND-MEET graph: points to check and measures to take
Several hours after starting measurements:
A ze ro point drift occurs due to cha nges in the balance interna l temperature cau sed by turning the power on.
Warm up the balance until the balance reaches equilibrium with room temperature.
Changes in temperature in a day are great:
Use an air conditioner to avoid changes in temperature.
When using an air conditioner, use much care to avoid the direct airflow to the balance from the air
conditioner.
Sudden temperature changes occur:
If the causes of the temperature change such as a heat generating device are known, eliminate the causes.
The temperature fine fluctuation occurs:
The air from the air conditioner may be blown directly to the balance.
Use a breeze break or change the balance installation site to avoid the direct airflow to the balance
from the air conditioner.
The repeatability is bad even if changes in temperature are small.
The air from the air conditioner may be strong. Use a breeze break to avoid the direct airflow to the
balance from the air conditioner.
Sources of vibration may exist near the balance.
The repeatability during the day is bad while the repeatability at midnight is good.
Human activities such as opening or closing the door, passing near the balance may influence the balance.
Take appropriate measures to avoid passing near the balance while the balance is in use.
Temporal poor repeatability
Impact may have been applied to the balance or table on which the balance is installed.
Or an earthquake may have occurred.
Others
Sudden changes in barometric pressure due to typhoon or building vibrations due to strong winds
will influence the balance.
Environment to install a microbalance.
Location
The best location is the first floor of the rigid building built on solid ground.
Locations along the coast or main roads may be influenced by winds and vibrations.
Room
Corners of the rooms or areas near a pillar, far from the passage, door or air conditioner outlet and
where there is no direct sunlight.
A weighing table should be solid and made of stone or wood having low heat conductivity.
Temperature / barometric pressure / static electricity
Changes in temperature in a day: within 4°C
Changes in temperature in a short time: within 0.2°C/30 minutes
Changes in barometric pressure in a day: within 10 hPa
Static electricity: active elimination is required especially for the balance with a minimum display of
1 mg or less which is more prone to static electricity.

13. MAINTENACE
Do not use organic solvents or chemical cloth to clean the analyzer.
Clean the analyzer with a lint free cloth that is moistened with a mild detergent.
Do not disassemble the analyzer.
Use the original packing material for transportation.
14. TROUBLESHOOTING
14-1. Checking the analyzer performance
If the analyzer seems to have a problem, check the items described below.
If improper performance persists after checking, contact the local A&D dealer for repair.
Checking the power supply
Is an appropriate AC adapter connected?
Checking the data transmission
Is the analyzer connected to the balance using an RS-232C straight through cable?
Are the RS-232C settings of the analyzer the same with those of the balance?
Are the RS-232C settings of the analyzer the same with those of the printer, if connected?
14-2. Asking for repair
If improper performance persists after checking, contact the local A&D dealer for repair.
The analyzer is a precision instrument. Use the original packing material for transportation.

15-2. Options
AD-1687 weighing environment logger
Equipped with four sensors for temperature, humidity, barometric pressure and vibration, the AD-1687
can measure and store environmental data.
When connected to an RS-232C interface of a balance, the AD-1687 can store environmental data
along with measurement data.
Can be used for balance daily checks, periodic checks and uncertainty calculations.
When connected to a USB port of a computer, the stored data can be read into the personal computer.
The AD-1687 is recognized as USB memory and special software is not required.
AD-1602 series calibration weight
Calibration weight conforming to OIML, Class E2 or Class F1
Can be used for balance daily checks, periodic checks and uncertainty calculations.
Wide range of capacities are available, from 1 g to 20 kg.
