7.14 Desiccant Alarm
When the humidity detector in the TB500 indicates that the internal environment is close
to the point where humidity could cause condensation, the instrument will display DESC
as a warning. If desired, a desiccant warning can activate the alarms and send the 4-20mA
to 2mA. To activate the alarms when the desiccant fails, select On in the DESC menu.
The default for this menu is OFF. Make selections using the
t and u buttons then press
the
↵ button to move to return to AUTO mode.
7.15 Saving Configuration Settings
If extended settings are set to OFF, pressing the
↵

TB500 will automatically return to the normal AUTO mode of the instrument.
If extended settings are set to On, after the last menu of the extended settings, pressing the
↵
button will save all settings and the TB500 will automatically return to the normal
AUTO mode of the instrument.
The CONFIG menu may be used at any time to reset or change any of the parameters.
The CONFIG menu may be exited at any point in the menu by using the MODE/EXIT
