Math
Next in the signal processing sequence is a Math operation (mX+b, Percent, or Recipro-
cal). These math operations allow you to mathematically manipulate the reading (X) that
is applied to this block in the flowchart. With one of the Math functions enabled, the math
result is calculated as shown in
NOTE
Limits
The reading that is applied to the Limits block in the flow chart is not modified and is the
reading that is displayed on the Model 2750. With Limits enabled, the reading is tested
against two sets of high and low limits. Along with the displayed reading, annunciators
and messages are used to indicate the result of the limits testing.
NOTE
Buffer
With the buffer (data store) enabled, each displayed reading is stored and timestamped.
The buffer also provides statistics on the stored statistics. Buffer statistics include mini-
mum and maximum, peak-to-peak, average, and standard deviation.
When buffer recall is enabled, stored readings and the buffer statistics are displayed on the
Model 2750.
