calibration of your balance.
□ Automatic Self Calibration, using the built-in weight, adapting to changes in
temperature.
□ Automatic Response Adjustment, adapting to vibration and drafts in the
environment.
□ Data Memory Function, storing 200 weighing data.
□ Interval Memory Mode, storing weighing data periodically.
□ Good Laboratory Practices (GLP) data output using a serial interface.
□ Under Hook, for measuring specific gravity and magnetic substances.
□ The balance is equipped with the specific gravity measuring mode to
calculate the specific gravity (density) of a solid.
□ Multiple Weighing Units, with most of the common units used around the world.
□ RS-232C serial interface, for transmitting data and controlling your balance.
□ Door Control Lever, a front mounted door control can easily open and close
one of the side doors if connected using the door joint.
