4-2-4~6. Humidity setting
Technical Reference Manual
For the check and adjustment of the track alignment using an alignment
disk, set the environmental relative humidity to the SKA in order to
improve the precision of measurement.
This setting is important when the relative humidity is considerably
different from 50\.
The initial setting of the following is not required if the relative
humidity is the same as the initial value (50\) of the SKA.
(1) Key in "E2". (CALIBRATION RH ALIGNMENT)
(2) The relative humidity set at that time is indicated in the latter
two digits of the DATA indicator CIJLIJ l\).
(3) Input the relative humidity percentage in the measurement environment
(two digits, Max.).
e.g. RELATIVE HUMIDITY 58\: E2 58
4-2-4-7. Setting of SKA gain
For this FDD, the SKA gain should be maintained at the initial state
(H GAIN indicator is off). If the H GAIN indicator turns on by an
erroneous key-in, turn it off by keying in "DO".
