4.3.3 CHANNEL/ALARM CONFIGURATION (Cont.)
SCALE TYPE (Cont.)
SCALE DIVISIONS - MAJOR
Appears for Linear Scale types only. Setting major divisions to 1, means that the scale consists only of
‘zero’ and full scale. Setting Major divisions to 2, means that the scale has divisions at zero, 50% and full
scale, and so on. Intermediate scale values appear at major divisions if there is suffi cient space. Default =
10 for large frame recorders or 5 for small frame units.
SCALE DIVISIONS - MINOR
Appears for Linear Scale types only. With minor divisions set to 1 (default), the scale major divisions are not
divided i.e. no minor division tick marks appear . Setting Minor divisions to 2, means that each major scale
division is divided into two, and so on. See fi gure 4.3.3b1 for an example showing fi ve minor divisions.
LOG
For some input type selections, this appears only if ‘Scaled’ is ticked.
Channels with Scale Type = Log, appear with logarithmic scales. These scales have major divisions at
each decade boundary, and (space permitting), minor divisions for mantissa values 2 to 9. Examples are
shown in fi gure 4.3.3b1. Because of the nature of logarithms, neither negative values nor the value 0 can
be used as scale ‘zero’. Linear inputs are traced as exponental curves (fi gure 4.3.3b2).
LOG/LINEAR
For some input type selections, this appears only if ‘Scaled’ is ticked.
Channels with Scale Type = Log/Linear, appear with logarithmic scales. These scales have major divisions
at each decade boundary, and (space permitting), minor divisions for mantissa values 2 to 9. Examples
are shown in fi gure 4.3.3b1. Because of the nature of logarithms, neither negative values nor the value 0
can be used as scale ‘zero’. Linear inputs are traced as straight lines (fi gure 4.3.3b2).
