Point Programming
Custom programming allows you to define functions and personalize
features for performing specific applications and tasks. The programmed
information is stored in nonvolatile memory. Programming is via menu-
driven prompts.
The standard recorder is a 36-point recorder, of which a maximum of 18
points may be live inputs; these are typically voltages or currents. Any point
not being used to record or display live inputs may be used as a
computational point. Inputs can be conditioned or scaled to display any
range of engineering units.
There are four distinct levels of data handling:
 Conversion: Conversion applies only to live inputs and is the process of
converting real-time analog signals into a 16-bit digital value that can
be used by the recorder. There are six bipolar, full-scale ranges for all
conversions: 50 mV, 100 mV, 200 mV, 1 V, 5 V, or 10 Vdc, full scale.
The converted values pass to a conditioning block which converts the
binary value, effectively a percentage of full scale, into a value useful to
the user.
 Conditioning: Conditioning includes converting the binary value into a
representative voltage, conditioning and linearizing this voltage to
represent, for example, a real world temperature as might be input by a
thermocouple or RTD, and applying any other computation as
required. The conditioning block handles all channels. The outputs
from the conditioning block are referred to as base points and may be
fed back to the inputs of the conditioning block to form the basis (base
point) for other base point computations. This process includes
tracking peak or valley values and calculating moving averages, timed
averages, difference, totalization, or any other user-entered equation.
The input to any point in the conditioning block can be any one of the
base points or can be the live inputs. Live inputs can have input and
output scaling applied in the conditioning block unless this is
pre-defined by the nature of the input, such as thermocouples.
