Hand-held Analyzer Types 2250 and 2270 – User Manual
(Cont.) Recording Control Set to All Events to record while any of the events
above are active, however, take Maximum and
Minimum Duration into account
If you do not want to record the input signal, then set
Recording Control to Off, to economise on power
Set to Image Event (Type 2270 only) to make a
recording of 1 s + Pre-recording Time + Post-recording
Time
Note: For Reverberation Time Software
BZ-7227, the values are limited to Off and Automatic.
Set to Automatic to make signal recordings during the
measurements
Recorded Channel Ch.1
Ch.2
Both
Select Ch.1 or Ch.2 to record that channel or select
Both to record both channels simultaneously.
Recording Quality Low
Fair
Medium
High
This setup determines the quality of the recording by
adjusting the sampling rate.
The amount of space required for the recording will
depend on the selected quality (see details in the
Specifications chapter)
Recorded Signal
†
Microphone:
Input X-weighted
Input C-weighted
Input Z-weighted
Accelerometer and
Direct:
Input Linear
Use this parameter to select the frequency weighting
of the recorded signal
Note 1: The frequency weighting of the recorded
signal can be selected independently of the frequency
weighting of the measurement, the signal at the output
socket and the signal at the earphone socket
Note 2: X = frequency weighting A or B. ‘A’ requires
that the BB (excl. Peak) parameter is set to AC or AZ.
‘B’ requires that the BB (excl. Peak) parameter is set to
BC or BZ
Note 3: Recording in 2-channel templates will only
record Input Z-weighted for Microphone input
