Introducing The Next Generation Of
Automated Weighing Applications
Today, it has become commonplace for materials to be weighed with automated devices.
As precision balances are increasingly used in that way not just in production
lines/systems but also in laboratories, users now face a range of unexpected problems.
Introducing The Next Generation Of
Automated Weighing Applications
Fact 1: Precision balances are designed to measure static loads only.
The weight sensor of a precision balance,
regardless of its
manufacturer
, breaks in a short period if it is continuously
affected by loads with acceleration (i.e. impact shocks). This
typically occurs in factories where materials are placed roughly
by machines or thrown by operators onto balances. In addition,
impact shocks can easily shift values and cause errors.
The difficulty is that even if you know the above, you may
not know what degree of impact shock is safe or unsafe for
the balance to take necessary preventive measures such as
refining the automatic loading mechanism.
Solution: Impact Shock Detection (ISD) ♦                                    ♦ Patented
The GX-A/GF-A series visualizes the magnitudes of impact shocks that the weight sensor receives at
four levels. It beeps once at Level 3 and twice at Level 4 (both of which should be avoided).
Cushioning under the weighing pan
The two leaf springs that support the weighing pan of the GX-A/GF-A
series also mitigate impact shocks significantly.
Overload protection
The weight sensor is well protected against vertical and transverse
static
overloading. It won't break due to malfunction of the weighing system's
actuator and the resulting excess load. A&D's testing demonstrated that
even a human did no damage to the balance by stepping on it.
Fact 2:
Precision balances are intended to be used in a stable environment.
The performance (repeatability as well as display stability) of a precision balance is worsened by
external disturbances such as drafts and vibrations, which is often the case in the field. Therefore,
it is strongly recommended to evaluate whether the set-up conditions are appropriate. Checking
repeatability, however, is cumbersome, especially once the balance is embedded in a system.
Further, it is not uncommon that users don't have an adequate test weight.

Standard deviation calculated
using ECL
Solution: Auto Precision Assessment (APA)
The GX-A/GF-A series is designed with A&D's latest technology, Electronically Controlled Load (ECL).
This technology artificially generates a minute load (0.3 to 3% of the weighing capacity) by altering
the equilibrium state of the weight sensor.
♦
After making a quick diagnosis of whether there is a
critical failure, the balance indicates the standard deviation (i.e. repeatability) calculated from 10
repeated measurement with ECL on the spot. The entire process takes only 1.5 minutes.
♦ Patent pending
Adjustable response characteristics
You can trade weighing speed for higher display stability*1 or vice versa by selecting one of three preset
response characteristics (FAST, MID or SLOW). *1 This is not to improve repeatability.
Fact 3:
Internal clocks of precision balances are never in complete
sync with those of external devices.
This clock time disparity manifests as a problem most noticeably when you measure and record
flow rates of pumps, feeders and other devices at short intervals*2 with a balance connected to a PC
that performs the calculation. The timing at which the balance receives the command from the PC
to send the weight value and its display refresh cycle gradually go out of alignment. In
consequence, the PC intermittently produces irregular values (spikes when graphed) even if the
actual flow rate is constant. *2 Flow rate is determined from the weight variation that occurs during a given interval.
Solution: Flow Rate Display (FRD)
The GX-A/GF-A series can calculate and display/output the mass flow rate (the unit of measure can
be selected from g/s, g/m or g/h), or the volume flow rate (mL/s, mL/m or mL/h) by entering the
density of the material. Up to 10 densities can be saved to the device. Both the display refresh rate
and interval (set between 1 second and 1 hour) are regulated by the same internal clock of the
balance, making measurements free from the aforementioned problem.

Time disparity of two different internal clocks (when the balance display refresh rate
is 5 times/sec, the interval is 1 sec, and the balance's internal clock goes slightly ahead of the PC's)
RS-232C and USB interfaces as standard
For the USB interface, you can toggle between the
Quick USB mode (plug-and-play with weighing data
output to a PC only) and the Virtual COM mode (for
bi-directional communication*4) with internal
settings. A USB cable is provided as standard.
*4 A special driver downloaded from the A&D website needs
to be installed on the PC (except those with Windows 10).
Large, easy-to-see spirit level with LED
illumination
The illumination blinks for 5 seconds after the
display is turned on to indicate that the balance
level needs to be checked.
Reverse backlit LCD display
The contrast of black and white
provides excellent visibility even in
poorly-lit areas and also prevents
eye fatigue.
Leveling feet with thumbwheel
The leveling feet can be adjusted up
or down smoothly using large
thumbwheels.
Security slot
An off-the-shelf (such as Kensington)
anti-theft lock can be used to prevent
the balance from being lost.
3
Flow rate comparator
The indication allows you to monitor whether the flow rate is kept within the designated limits.
Tare memory
The tare value can be saved in non-volatile memory so that the remaining amount of the material in the
container can be displayed again*3, even if power is disrupted for any reason during loss-in-weight measurement.
*3 When this function is activated, the power-on re-zero/tare is turned off.
On top of the above, the GX-A/GF-A series has many advanced and practical
features and is perfect for manual weighing applications.
Data management, documentation and compliance
Minimum weight calculation based on the APA
From the standard deviation obtained using ECL described earlier, the GX-A/GF-A series also
calculates and indicates the minimum weight at the installation location*5 in accordance with the
United States Pharmacopeia (USP) standard.
*5 The effects of the ambient environmental conditions on repeatability is taken
into account, unlike the values shown in catalogs as "ideal" or "typical".
Minimum weight alert
To ensure that the measured sample quantity meets the
minimum weight requirement, the GX-A/GF-A series can
display an alert until the sample quantity reaches the value
entered as the minimum weight.*6
*6 It is also possible to directly use the minimum
weight determined by ECL.
User access control (UAC) and key lock for data integrity
Use of the balance can be password-protected for authorized individuals (up to 11 including one
administrator)—the administrator can perform all operations including calibration while other users can
make measurements only. Moreover, upon receiving a command to disable its keys, the balance becomes
operable only by sending commands from an external device such as a PC.
Automatic self calibration (for the GX-A series)
The GX-A series can be set to calibrate itself automatically using its internal weight either (1) in response to
change in ambient temperature (approx. 10 ˚C) to prevent error due to sensitivity drift, (2) at a set interval
time, or (3) at predetermined (up to three) times of the day. Internal calibration can also be performed any
time with one key press.
GLP/GMP/GCP/ISO complia nt out put
For documentation requirements, the GX-A/GF-A series can output its manufacturer, model, serial number,
ID number, date + time, space for signature for calibration report, calibration test report, and title & end
blocks for a series of weighing results.
Universal Flexi Coms (UFC)
UFC lets you edit serial data output/printout format. With this function, label printing is also made possible by
connecting the balance to a commercially-available printer*7, and enabling arbitrary character strings output.
*7 Printers that can program printing content from the strings sent through RS-232C.
Please note that a cross cable is required depending on the printer.
Gross/Net/Tare output
On receiving a command or with key operation, the GX-A/GF-A series outputs the gross, net, and tare values
to an external device such as a printer, PC or PLC.
Statistical calculation function (SCF)
The GX-A/GF-A series can display and output statistical calculation data including number of data, sum,
maximum, minimum, range (maximum-minimum), average, standard deviation, and coefficient of
variation to facilitate the analysis of measurements.
