ATI
Model A15/82 Fluoride Monitor with Auto-Calibration

O&M Manual
Rev-G (6/10)
FRONT PANEL LOCK
The key switches on the front panel of the monitor can be used for both changing the display and for
calibrations and setpoint adjustments. When the monitor is shipped from ATI, all functions are accessible.
However, the adjustment and calibration functions can be locked in order to prevent unauthorized adjustments to
the instrument. When the front panel is locked, the MODE key will still allow the display to be stepped through
the alternate displays but will not allow settings to be altered.
To lock (or unlock) the keyboard, press the MODE key until “CONFIGURATION” is displayed. Press the
CAL key once and the display will change to “KB UNLOCKED”. Use the UP key to select “KB LOCKED” and
press ENTER. The UPDATE message will appear briefly and the “LCD CONTRAST” message will appear.
Press the MODE key 3 times to return to the main display.
