Delivery condition
The two parameters LDW und LWT give you the opportunity to adapt the
characteristic curve to meet your requirements (scale characteristic curve) and
you can use the NOV command to standardize the measured values to the
required scaling value (e.g. 3000 d). Detailed information can be found in the
help file.

Signal processing
Fig. 5.2
Signal flow diagram
After amplification and A/D conversion, the signal is filtered by adjustable
digital filters.
The commands ASF and FMD are used to set the cut-off frequency of the
digital filters. The command ICR is used to change the output rate (measured
values per second).
The user can set their own characteristic curve (commands LDW, LWT and
NOV) without changing the working standard calibration. Gross/net selection is
also available (TAS command). Command ZSE activates an automatic zero on
start-up function. An automatic zero tracking function (ZTR) is also available.
A command (LIC) is available for linearization of the scale characteristic curve
(with a third order polynomial). The polynomial parameters can be set using
the HBM PC program, AED_Panel32.
