9.1.6 Effect of a Full Reset on the Monitor’s Memory
A FULL RESET of the Monitor changes the data stored in its
Working Memory as follows:
1. All data stored in Display Memory and Background Memory is
deleted.
2. Values of the Optical Filter Set-up Parameters in Block 2 of The
Source Memory are copied into Block 2 of the Working Memory.
3. The active values of the other set-up parameters in Block 3 of the
Working Memory are replaced by the factory-set values defined
in Block 3 of the Source Memory.
4. The active values of the Optical Filter Parameters in Block 2 of
the Working Memory are replaced by the values of the optical
filter parameters in Block 2 of the Source Memory. Note that
under normal circumstances the data in these blocks is the same.
However, to ensure that the data in these blocks is the same,
data is read from Source memory into the Working Memory
during a FULL RESET of the Monitor.
5. Those Filter Bank Nos. which have been made active determine
the calibration factors which will be found in Block 1 of Working
Memory after a FULL RESET of the Monitor. If, for example the
active Filter Bank No. chosen for all the filters “A” to “E” is no. 1,
then only the calibration data in files A 1; B 1; C 1; D 1; E 1; and
W will be found in the Monitor’s Working Memory after a FULL
RESET. This example is illustrated in Fig.9.4.
