1 Introduction

Thank you for choosing a METTLER TOLEDO balance. The balance combines high performance with ease of use.

This document is based on the software version V 2.0.301.

Disclaimer for comparators

In this document, the term "balance" is used to describe both balances and comparators.

Comparators are characterized by their higher resolution compared to balances and are mainly used for differential weighing application, such as the calibration of standard weights. Beside standard balance tests, comparators have also been tested with differential repeatability (ABA repeatability) during production.

3.6.6 Icons and symbols

3.6.6.1System status icons

System messages can appear due to a user action, a user input or a system process. Some messages leave it up to the user to choose upon acting, they will disappear after acknowledging. Other messages remain persistent, so the user can defer them but eventually has to handle them. These messages can be seen in the main status bar on the upper right-hand side of the display.

Icon	Name	Description
	The balance is out of level.	The balance must be leveled. Information about leveling the
		balance can be found in the section Leveling the balance. When
		the balance is leveled the symbol appears.
	Information	Information messages appear due to user actions or system
		processes and offer opportunities that are related to the current
		action or process.
	Warning	Warning messages appear due to user actions or system
		processes that could lead to a problem that can be prevented.
	Error	Error messages appear due to user actions or system processes
		that have failed. It is mostly still possible to handle such a
		problem.

3.6.6.2 Weighing status icons

Weighing status icons appear due to the weight value matching certain quality criteria. The information on the status can be looked by tapping on any of the visible weighing status icons.

Icon	Name	Description
	Stability indicator	When the stability indicator appears, the balance is not stable.
		Make sure that the balance is placed at an adequate location.
		Information about the adequate location can be found in the
		section Selecting the location.
	Net indicator	Appears when the tare key has been pressed and the tare weight
		has been subtracted.
	Calculated value	The current weight value is calculated. This symbol only appears
		in the weighing value area when a container has been used with
		the function Preset tare.
	Minimum weight violation	The current weight value is smaller than the defined minimum
		weight. Make sure that the weight is larger than the minimum
		weight.
GWP	Balance invalid	The current balance configuration is invalid or quality criteria have
		not been fulfilled according to the GWP approved definition.
GWP	Weight not ready	The current weight measurement is not ready according to the
		GWP approved definition. This can be caused an overload, an
		underload, or a minimum weight violation.
