• Restrictions due to element coefficients
The PT uses element coefficients to manage display elements. The maximum number of display coefficients
that can be used at the same time is 1024.
If the total of the element coefficients on a screen exceeds 1024, the elements after this total has been reached
are not displayed.
The element coefficients for each element are indicated in the table below. Ensure that the total for the screen to
be displayed is not greater than 1024.

One numeral memory table
When numeral memory tables are designated for each of the –100%,0%, and 100%
settings for each graph line, one numeral memory table is read for each of these
settings.
Number of numeral memory tables determined by number of graph lines
vertices
When numeral memory tables are designated for each of the –100%, 0%, and 100%
settings for each graph line, one numeral memory table is read for each of these
settings.

Number of numeral memory tables determined by
the number of graph lines
When numeral memory tables are designated for
each of the –100%, 0%, and 100% settings for
each graph line, one numeral memory table is
read for each of these settings.
Number of background memory tables
determined by the number of graph lines
When numeral memory tables are designated for
each of the –100%, 0%, and 100% settings for
each graph line, one numeral memory table is
read for each of these settings.
