Page 3: Functional Description
FUNCTIONAL DESCRIPTION These instruments also feature a controlled access to calibration and GLP settings through a password protection method. The Battery Error Preventing System (BEPS) detects when the batter- ies become too weak to ensure reliable measurements. The backlight feature is automatically disabled when the batteries are getting low and a clear indication is displayed to warn the user of this condition. -
