The 6TC control menu
In addition to configuring the mode for normal operations, it is also
possible to set the instrument temporarily into short-period mode, in
order to assess the effects of adjustments to the instrument's
inclination during installation.
Option
(Short-period mode) over-rides any selected response
mode (whether hardware or software configured) and temporarily
changes the response mode to one second (SP) for as long as the
control menu is active – i.e. until the system is allowed to boot
normally or “broadband mode” is selected (see option
, below).
Option
(Broadband mode) cancels the temporary short-period
mode and restores the configured response mode. Note that, when
the instrument boots, it will always revert to the normally configured
response mode.

Other controls
Option
displays the current mass positions.
Option
returns the internally measured inclination.
Option
resets the offset-null. This can be used when the internally-
measured inclination appears to be different to the actual inclination.
Resetting the offset should result in an internally measured inclination
reading of 0°, regardless of the actual, physical inclination.
Option
exits the control menu and continues with the normal boot
process.
