4-2-4-3. Setting of step rate and settling time
Technical Reference Manual
Generally, the step rate and the settling time of the FDD is the same
as the initial value of the SKA (step rate: 6msec, settling time: 15msec)
and no initial setting is required.
For the confirmation or the change of the initial setting, execute
according to the following procedure. Once the setting is done, it
will be maintained until the main DC power (for SKA) is turned off, or
until the RESET switch of the SKA is depressed.
(1) Key in "DB". (SET STEP RATE)
(2) Step rate set at that time is indicated by O.lmsec scale on the DATA
indicator 0I1J (ms).
e.g. DATA indicator ~ indicates 6.Omsec.
(3) Key in a new step rate down to one decimal place (unit: msec).
Note: If there is no change in step rate in item (2), omit item (3) and
forward to item (4).
(4) Key in "F". (STOP -- Setting of the step rate completes.)
(5) Settling time at that itme is indicated by O.lmsec scale on the DATA
indicator CIJClJ (ms).
e.g. DATA indicator ~ indicates 15.Omsec.
(6) Key in new settling time down to one decimal place (unit: msec).
Note: If there is no change in settling time in item (5), omit item (6)
and depress "F" key to complete the operation.
