Other Marks Used:
……This symbol indicates either: (1) that this gas was not measured;
or (2) that this gas was not selected to be printed out (see section
12.5).
9.3 Storage Space in the Display Memory
Table 9.1 illustrates the space, which is required to store individual
measurement results. If 5 gases and water vapour are being
measured, then 37 bytes of space are required to store
measurement results from one measurement cycle, whereas only 24
bytes of space are required if 3 gases (for example, gas A, E and
water vapour (W)) are measured. If only one gas (for example, gas
A) is being measured, then only 15 bytes of space are required to
store measurement results from one measurement cycle.
The total space available in Display Memory to store data is 64 000
bytes. If only one gas (for example, gas A) and water vapour is
measured, then data from up to
6400
measurement cycles can be stored in Display Memory,
= 3368
19
whereas if 5 gases and water vapour were measured, data from up
to only 64000 = 1730 measurement cycles can be stored in Display
37
Memory.
The time required to perform a measurement cycle is dependent
upon the number of gases/water vapour being measured.
If we take the examples given above we can work out approximately
how long the data from a monitoring task can be stored in Display
Memory:
