7. Configuration
Configure the leak monitor by following the steps below.
a. POWER-UP: Apply power to the leak monitor and wait for the power-up sequence to complete. Note that the
yellow fault light may flash at this time. The green power LED will flash to indicate that the monitor is in Warm
Up Mode. The monitor takes about 15 minutes to warm up; after which, the MONITOR ON light glows
steadily and the Data Display screen is displayed.

b. ACCESS FUNCTION SCREENS: Function screens are used to set up the monitor. After the microprocessor
board has been replaced, you must verify your monitor’s new configuration settings against the previous
settings that you collected in Section 3. With the monitor in Display Mode (solid green LED), access the
menu by pressing any keypad button.
c. COMPARE CURRENT AND SAVED SETTINGS: Use the keypad buttons to move the arrow (>) on the
display to highlight each function. Verify that the value of each function matches the previously collected
settings. (Refer to the table on the next page.)

d. EDIT SETTINGS AS NEEDED: If a setting needs to be changed, be sure that the desired function is
highlighted first (see previous step). With the desired function highlighted, you can edit the value by pressing
the ENTER button and then by using the keypad to scroll through the displayed data and change the value
associated with that function. Press ENTER to save newly entered values. Press the QUIT button to return to
the previous screen without saving.
NOTE
If no buttons are pressed within 90 seconds after selecting a function, the monitor returns to the
Data Display screen.
Use the table below to enter pre-procedure settings and to confirm them after the new microprocessor board
