Test Output Parameters; Diagnostic Mode Test - NuAire NU-5510 Operation And Maintenance Manual

8.8.1 Diagnostic Mode
The diagnostic mode allows the operator to configure and/or check the Incubator for input/output
signals manually and individually. The diagnostic mode has three menus to select from that are
the following:
1)
2)
3)
To initiate the diagnostic mode, perform the following:

In either run or setup mode, press and hold the hidden key (flag on NuAire logo) for four
seconds. Temperature display will indicate the first menu "test".

To advance to the second menu, press ▲ key, temp. Display will indicate, "opt".

To advance to the third menu, press ▲ key, temp. Display will indicate "rst".

To repeat the menus, continue to press the ▲ key, which will advance the menus in a round
robin fashion.
The "tst" and "opt" menus each have several function parameters as described below. The "rst"
menu performs a master reset function, which clears the microprocessor's memory and resets all
parameters to their default condition.
To enter the function parameters, press the "SEL" key while the temp. display indicates the desired
menu. Then, while in the menu, press "SEL" key to advance through the function parameters,
again, in a round robin fashion. Once in the desired function parameter, press the ▲or ▼ key to
alter or toggle on/off.
