Appendix
The Diagnostics and Service menus are intended for factory-
trained personnel only, and access is limited by requiring a
service passcode. These menus allow the factory default data,
including calibration data and sensor parameters, to be adjusted.
Please contact an applications or service engineer at GE Sensing
if access to these menus is required. Normal operation of the
HygroTrace does not require access to the information contained
in these menus.
Diagnostics
A Diagnostics Display page can be selected from the Display
Menu (see Figure 11 below), but can be accessed only by using
the service passcode.
