Page 103 of 199

There are four different blocks of data in the Working Memory (see

Fig. 9.1

):

Block 1 – contains only calibration factors and 3 optical-filter

parameters from each of the active “Filter Banks”.

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 – 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 5 – 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 1 – Calibration Factors and 3 Optical-filter Parameters

from Each Active Filter Bank:

If, for example, 5 optical filters are installed in the Monitor and their

UA numbers have been entered in the active set-up and Filter Bank

No. 2 has been selected for filter “A”; no. 4 for filter “B”; no. 3 for

filter “C”; no. 1 for filter “D” and no. 1 for filter “E”, then only

calibration factors from filter banks A2, B4, C3, D1, E1 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 either an optical filter’s UA number or its 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
