Block 2 – contains 2 of the 5 optical filter parameters with values
which are the same as those found in Block 2 of the
Source Memory.
Block 3 – contains all other set-up parameters (i.e. excluding the
optical filter parameters) with active set-up values.
Block 4 – contains data collected during the performance of a
monitoring task. This data block is named the Display
Memory because this data is displayed on the Monitor’s
screen while a monitoring task is being performed.
Block 5 – this block contains measurement data, which was copied
into it from the Display Memory. This block is called
Background Memory because the data stored in it cannot
be accidentally deleted.
Block 1 – Calibration Factors and 3 Optical-filter Parameters
from the Active Filter Bank:
If, one optical filters are installed in the Monitor and the UA0988
have been entered in the active set-up and Filter Bank No.1 has
been selected for filter “A”; then only calibration factors from filter
banks A1 and W will be stored in this block of data (see Fig. 9.1 ).
The name, molecular weight and alarm limits of each gas will also be
stored in this block.
Block 2 – Optical Filter Set-up Parameters:
Whenever the optical filter’s active Filter Bank Number is changed,
the same values are automatically read into Block 2 of the Source
Memory.
Block 3 – Other Set-up Parameters:
The active set-up values are those values, which are underlined by a
cursor on the display screen of the Monitor when it is operated in
Set-Up mode.
Block 4 – Measurement Data:
Whenever the Monitor performs any operation, which results in data
occupying the Display Memory, the data already stored there will be
deleted. To reduce the risk of accidental losing data from Display
Memory, a warning "WARNING: DISPLAY MEMORY WILL BE
DELETED” is displayed whenever a user attempts to perform an
operation with the Monitor, which will result in the deletion of data
from Display Memory.
Data in Display Memory can be copied into the Monitor’s Background
Memory (see Block 5 below) to protect it against accidental deletion.
