SV 977D User Manual - Appendixes
09xxxh – reserved block,
0Axxxh – pause marker block,
0Bxxxh – marker block of discontinuity of basic results records,
0Cxxxh – other marker blocks.
In general, the rule is that in the first word of the block the bit b11 is deleted and in the last word the bit b11 is
set, except for the user marker block (08xxxh), because the block consists of only one word. If the highest four
bits of the start or end of a block word are not any of the numbers from 08h to 0Ch, then we are dealing with
a block of the basic result record. The table below shows the structure of the record of the basic results record
and the structure of the markers.

Flags
bit 0 (overload flag):
0 – no overload
1 – overload occurred
bit 1 (excessive vibration flag):
0 – no excessive vibration
1 – excessive vibration
bits 2..7 – reserved
bits 8..(7+n) – underrange flags in “n” profiles:
0 – the signal level is equal to or greater than the declared lower
range of measured values
1 – the signal level is lower than the declared lower range of
measured values
remaining bits are reserved
1..
[ResProf_1[..]]
measurement results of the first profile:
– number and order of results is determined by the result bit mask in
the profile parameter block (see Table B.14, the word "LoggerRes")
– results are in format 0,01 dB
...

...
[ResProf_n[..]]
measurement results of the n
th
profile:
– number and order of results is determined by the result bit mask in
the profile parameter block (see Table B.13, the word "LoggerRes")
– results are in format 0,01 dB
– The number of profiles comes from the corresponding parameter
in the main parameter block (see Table B.12, the word "00nxxh")
...
[ResRPM[2]]
lowest and highest word of the RPM measurement result value:
– result is available if the RPM measurement is enabled (see the
word "RPM_On" in the measurement parameter block - Table B.7)
– value of the result is calculated according to the formulas given in
the comment of the RPM measurement results block (see
Table
B.44)
