ATI A15/76 Turbidity Monitor Part 4 – Startup

O&M Manual

Rev-H (8/11)

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.
