Accuracy; Parameters - Maretron CLM100 User Manual

CLM100 User's Manual
Depending on the type of data being monitored, resolution might further be limited by the
resolution of the underlying NMEA 2000 data types used to transmit the parameter value. For
example, if you connected a DC voltage sensor with a range of 0-20VDC to the CLM100, the
CLM100 could measure the parameter transmitted by the CLM100 to a resolution of 0.067V;
however, NMEA 2000 can only represent voltage to a resolution of 0.1V, so in this case, the
NMEA 2000 data representation is what limits the resolution of the parameter values that will
be transmitted over the NMEA 2000 network to 0.1V.
Finally, the resolution to which the CLM100 can measure a parameter may be limited by the
current loop transducer. If the current loop transducer's resolution is lower than that of the
NMEA 2000 representation and the CLM100's current measurement capability, then the
resolution of the current loop transducer will limit the resolution of the value that will be
transmitted over the NMEA 2000 network.
Please refer to the configuration section (Section 4) for information on units and NMEA 2000
range and resolution for the different data types supported by the CLM100.

1.8 Accuracy

The CLM100's accuracy is specified at 1% of the full scale. From the previous example, that
means that the humidity value transmitted by the CLM100 will be within 1% of the humidity
value transmitted by the humidity sensor over its 4-20mA current loop interface. When
considering the accuracy of the measurement on the NMEA 2000 network, the accuracy
specification of the sensor itself needs to be considered along with the CLM100's accuracy
specification.
