TEST METHODS SPECIFICATIONS INTRODUCTION Fluoride may occur naturally in some ground waters or it may be added to public drinking water supplies to maintain a 1.0 mg/L concentration to prevent dental cavities. At higher concentrations, fluoride may produce an objectionable discoloration of tooth enamel called Fluorosis, though levels up to 8 mg/L have not been found to be physiologically harmful.

LOGGING DATA The default setting for the data logger is enabled. The meter will log the last 500 data points. The counter in the center bottom of the display will show how many data points have been logged. The display will show 500+ when the data logger has exceeded 500 points and the data points are being overwritten.
FACTORY SETUP The Factory Setup menu is used in manufacturing of the colorimeter. This menu is not for use by the operator in the field. SETTING POWER SAVE The power saving Auto Shutoff feature will turn the meter off when a button has not been pushed for a set amount of time.
SETTING THE BACKLIGHT TIME The backlight illuminates the display for enhanced viewing. The default setting is 10 seconds. If Button Control is chosen the backlight button on the key pad will act as an on/off switch and the backlight will remain on or off when the meter is being used.

WATERLINK CONNECT The meter may be interfaced with any Windows-based 64 bit computer by using the LaMotte WaterLink Connect program and a USB cable. The program will store test information and results in a local database, and allow for exporting this data to a comma separated value (CSV) file. The meter will send the following data: time/date stamp, name of test, sample value, sample units, meter name, and location.
This unit uses a custom battery assembly that is only available from LaMotte Company. Battery replacement must be performed at a LaMotte authorized repair facility. The water resistant housing of this meter should not be opened by the user.

This information will enable the service department to make the required repairs more efficiently.
The menus can be displayed in seven different languages. The LaMotte tests are precalibrated for LaMotte reagent systems. The colorimeter displays the result of these tests directly in units of concentration.
THE KEYPAD The keypad has 6 buttons which are used to perform specific tasks. This button will scroll up through a list of menu selections. The button is used to select choices in a menu viewed on the ENTER display. This button controls the backlight on the display.
