CLM100 User's Manual

4.16.6 Configuring Pressure at 20mA

Program this parameter to match the reading of the pressure transducer when it is sourcing a
current of 20mA. You can determine this value by examining the specification of the pressure
transducer being used.

4.16.7 Configuring Data Damping Period

You can configure a damping parameter to smooth the pressure readings or make them more
responsive. The data damping is configurable between 0.2-25.0 seconds with a resolution of
0.1 seconds. The default data damping for a channel in pressure mode is 0.2 seconds.

4.17 Configuring a Channel in Decibel Mode

The following sections describe the parameters that are available for configuration for a
channel which has been set to decibel mode.

4.17.1 Configuring Instance Number

Program this parameter to match the desired instance number of the decibel reading for this
channel. You can program this parameter to any value between 0 and 252.

4.17.2 Configuring Label

Program this parameter with a text string which identifies the particular parameter being
monitored by this channel. Maretron display products will display this label text when you are
selecting data to display.

4.17.3 Units, Range, and Resolution

Maretron display products and software support the following units for display of decibels, with
the range and resolution shown in the following table (NOTE: the resolution may be further
limited by the capabilities of the CLM100; please refer to section 1.7 for details).

4.17.4 Configuring Decibel at 4mA

Program this parameter to match the reading of the decibel transducer when it is sourcing a
current of 4mA. You can determine this value by examining the specification of the decibel
transducer being used.

4.17.5 Configuring Decibel at 20mA

Program this parameter to match the reading of the decibel transducer when it is sourcing a
current of 20mA. You can determine this value by examining the specification of the decibel
transducer being used. This parameter may be set to a value of -327.64 – 327.64dB with a
resolution of 0.01dB.
