Device index number (<System> menu: Index)
The index number setting has no infl uence on performance or functions of
the unit. Setting an index number is optional. The setting range is 1 to 255.
Some possible uses for the index number capability are listed below.
1. Temporary management (classifi cation) of recorded data
Example 1 In a system where several DA-21 units are used, the
index number can serve to manage data according to
the unit on which the data were recorded.
Example 2 Manage recorded data according to measurement
purpose, measurement location, or similar.
Example 3 Manage recorded data according to measurement
parameters.
2. Using the index number as input range information
When using a system where a calibration signal is recorded in order
to calibrate recorded data, sensor range information will be required.
Using an input range value as the index number will facilitate data
management.
Example
Set the index number to 120 when a sound level meter
is calibrated in input range 120 dB.
