PRELIMINARY EXAMINATION Dear Customer, Thank you for choosing a Hanna Instruments Product. Remove the instrument from the packing material and examine it Please read this instruction manual carefully before using the instru- carefully to make sure that no damage has occurred during shipping. -
Page 3: Functional Description
The meters provide a controlled access to calibration and GLP settings FUNCTIONAL DESCRIPTION through a password protection method. To prolong battery life, the backlight and printing features are disabled when the batteries are getting low, and the "LOBAT" indication is displayed to warn the user of this condition. However, the meter continues to measure correctly even when the low battery indication is displayed. -
