1.2.Features

Automatic self calibration, using the internal mass, adapting to changes in temperature.

Response adjustment adapting to drafts and/or vibration automatically.

Memory function to store weighing data and calibration data.

When weighing data is stored only, 200 data can be stored in maximum. Interval memory mode to store the weighing data periodically.

Good laboratory practice (GLP) data can output using the RS-232C serial interface.

A built-in clock and calendar that can add the time and date to the output data.

Underhook, for measuring density and weighing magnetic materials.

Multiple weighing units with most of the common units used around the world.

Density mode for calculating the density of a solid.

Standard RS-232C serial interface to communicate with a computer.

Windows communication tools software (WinCT) to allow easy communication with a computer using Windows.

When multiple balances have the GH-08 Ethernet interface installed and are connected to a LAN, data can be acquired from them using the WinCT-Plus software.

1.3.Compliance

1.3.1.Compliance With FCC Rules

Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules.
