The balance in this video: GX-A / GF-A Series Multi-Functional Precision Balances from A&D
http://www.aandd.jp/products/weighing...

Features
Impact shock detection (ISD)*1 that visualizes what degree of impact shock is detrimental to the balance and allows users to take preventive measures as necessary
Flow rate display (FRD)*2 that makes calculating and recording flow rates easier and more accurate
Auto precision assessment (APA) and minimum weight calculation using electronically controlled load (ECL)*1
Cushioning under the weighing pan to mitigate impact shocks
Protection against vertical and transverse static overloading
Flow rate comparator that indicates whether the flow rate is within the designated limits
Tare memory function that saves the tare value in non-volatile memory
Alert function to ensure that the measured quantity is not smaller than the set minimum weight
Fast stabilization of approx. 1 second (approx. 1.5 seconds with the GX/F-1603A and GX/F-10002A)
Selectable response characteristics for trading weighing speed for higher display stability or vice versa
One touch calibration using internal weight (GX-A)
Automatic self calibration to maintain accuracy under temperature changes (GX-A)
Timed calibration function (GX-A)
Large, front-mounted spirit level with LED illumination
Easy-to-adjust leveling feet with thumbwheels
Clearly visible, reverse backlit LCD display
Multiple weighing units: g, oz, lb, lb-oz, ozt, ct, mom, dwt, grain, specific gravity, and a user-programmable unit for conversion applications (either tael, tola or Newton can be added upon request)
User access control (UAC) function that password-protects the balance at two levels
Key lock function to make the balance operable only by sending commands from an external device
Clock and calendar function
GLP/GMP/GCP/ISO compliant output to meet documentation requirements
Universal Flexi Coms (UFC) function to edit serial data output/printout format (Relevant Software: WinCT-UFC)
Gross/Net/Tare output
Data memory function to save weighing results, calibration results and unit masses for the counting mode in the device itself
Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function
Percent mode function for target weighing or checking sample variation
Animal weighing (average & hold) function for weighing moving objects
Statistical calculation function (SCF) to facilitate the analysis of measurements
Five-level comparator function with buzzer
Auto power ON and OFF functions
Density determination function (optional density determination kit available for the 0.001 g models)
Underhook for weighing a magnetic material as well as measuring density
Security slot in the rear of the balance to accommodate an anti-theft lock
