3.3 Setting Procedure
In orde
r to modify the settings with QDSP the current parameters must be loaded first.
Instrument settings can be acquired via a communications link or they can be loaded off-line
from a file on a local disk. The QDSP contains sample settings files for each product variant
that can be downloaded to show the range of settings available for the specific product.
These files can be modified and then stored under a different name allowing an instrument
configuration to be generated off-line without an instrument attached, and downloaded at a
later date.
Settings are displayed in the QDSP setting window, the left part displays a hierarchical tree
structure of settings, the right hand part displays parameter values of the chosen setting
group, see Figure 3-1.

3.4 General Settings
General Settings are essential for the operation of the measuring transducer. They are
divided into three additional sublevels (Connection, Communication and Security).
3.4.1 Description and Location
These are two parameters that are extended for easier recognition of a particular instrument.
They allow for the identification or location to be defined where measurements are
performed.
3.4.2 Average Interval
The averaging interval defines the refresh rate of measurements for communications display.
3.4.3 Maximum Demand calculation (MD mode)
The i4MC provides maximum demand values using the Thermal function.
3.5 Connection
The setting
of the connection parameters must reflect the actual applications or the
measurements will not be valid.
