Parameters
4.2.1 International standard selection
The table below contains all available measurement standards included. As
new countries with their local measurement standards (blasting, human
comfort and sensitive equipment) are added, some standards exist on only
one of the defined sales regions:
NO:
Nordic countries
EU:
European countries (except the Nordic countries)
IN:
All countries outside Europe
This is due for V12, from firmware version 2.0. V10 and V11 will
have the same standards as V12 for the Nordic countries (NO).
Explanations for the table below:
Frequency:
Tells whether the standard has a second interval channel/file
with frequency values. 0.5Hz resolution.
Weighting:
Standard can be set, or is permanently set, to use frequency
weighting of interval values and trigger levels. This is implemented in
different ways for the various standards.
Note! All filters mentioned below are implemented as time continuous digital
filters, calculated in real-time on each sample (4096Hz).
1.
“No”
No extra filtering in the pass-band between the frequency limits stated
in the standard definition. Geophone compensation filters may exist
when the standard is stated to have its low frequency limit below the
natural resonance frequency of the geophone.
2.
“ISO2631-2 type”
Used in human comfort standards only. Implemented by inserting a
high-pass filter (single pole at 5.6 Hz) prior to the RMS detector.
3.
“Norwegian type”
Used in some Norwegian standards. Implemented by more complex
