Mathematical Functions 6 Mathematical mits, a test can be evaluated as passed or not passed. The limits can be activated (ON) or deactivated (OFF) via soft menu key LIMITS. The limits will be displayed below the Functions main measurement value (Main). If a value falls below or exceeds the limits during a test, it will be reflected by the color display of the measurement value.
