Working with Records
Type 2239B is capable of saving up to 40 records of measured
results. This enables you to take several readings at different
locations or at different times of day and store each one for
future reference. All records can be recalled to the screen and/
or downloaded to a computer in a standard spreadsheet for-
mat.
4.1.1
Saving Records
A record is saved automatically after each preset-timed meas-
urement (see section 3.5.3). Results from a manually timed
measurement or an interrupted preset-timed measurement
must be saved manually. Records are numbered from 1 to 40
and are filled sequentially.
Each record holds the following information:
●
A
eq
●
A
eq4
●
A
eq8
●
A
mp
●
A
min
●
A
max
●
Frequency weighting
●
Time and date of measurement
●
Measurement duration
●
Overload status
Once all 40 records have been filled, no further records can
be stored until some or all of the stored records are erased.
You are able to erase the last record taken or all records at
once (see section 4.1.4).
