Table 9. Rate Scale
The input frequency can be linearly scaled using the Scaling Multiplier, Offset and Decimal
Point. The rate channel has an offset value as well. To illustrate, the following example will be
used:
1) Multiply
Input Frequency
by implied
Mode
multiplier
10000
x
1=
10000
2)
Multiply by user-specified
Scale
:
3)
Discard all digits to right of decimal place:
(If number is larger than six digits, it will not fit in the display)
5000
4)
Apply the user-specified
DP
location:
50.00
5) Add
user-specified
Offset
location:
250.00
-
100.00
=
150.00
(That is what will be seen of the display)
The following notation may be used to describe this behavior:
Display = INT [Fint x Scale] DP + Offset
