T for LXeq,T,mov 00:01:00 to
01:00:00
Sets the averaging time T (in minutes) of the moving
L
Aeq
and moving L
Ceq
. When the averaging time T
has elapsed the L
Aeq,T,mov
and L
Ceq,T,mov
parameters
will contain the L
Aeq
and L
Ceq
of the latest T minutes
– updated every second. in addition, you also have
L
eq,T,mov
=L
Ceq,T,mov
–L
Aeq,T,mov
. The L
Xeq,T,mov
is
not stored with the total data, but can be logged
(BZ-7224 and BZ-7225). The L
Aeq,T,mov,max
,
L
Ceq,T,mov,max
and the difference between the C- and
A-weighted values for the complete measurement
period are stored.
Note: There are two sets of these parameters,
allowing two simultaneous moving averages: e.g.,
one with 15 min averaging time and one with 1 hour
averaging time.
Charge Injection Calibration
‡
On
Off
Set to On for making a CIC at the start and end of
Logging. An Exclude marker is set on the profile and
Total parameters are not updated during the CIC.
Available for microphone input only.
Daily CIC
†
None
Once
Twice
Three times
Four times
Determines whether a Charge Injection Calibration is
performed one to four times a day or not at all. An
Exclude marker is set on the profile and Periodic
Reports and Total parameters are not updated during
the calibration. The results are saved together with
the Total parameters.
Available for microphone input only.
First Check
†
00:00:00 to
23:59:59
Set time of day for first CIC check
Note: The Check times must be separated from each
other by at least one minute. They should also differ
by at least one minute from the time set in the Save
Project Data at parameter.
Available for microphone input only.
Second Check
†
00:00:00 to
23:59:59
Set time of day for second CIC check.
Available for microphone input only.
Third Check
†
00:00:00 to
23:59:59
Set time of day for third CIC check.
Available for microphone input only.
Fourth Check
†
00:00:00 to
23:59:59
Set time of day for fourth CIC check.
Available for microphone input only.
*. For Sound Level Meter (BZ-7222) and Frequency Analyzer (BZ-7223) templates only.
†. For Enhanced Logging (BZ-7225) templates only.
‡. For Logging (BZ-7224) and Enhanced Logging (BZ-7225) templates only.
