5.5 Output Format Considerations
When using the Campbell Scientific floating point data format to store data,
the largest number the datalogger can store in Final Storage is 6999 in low
resolution mode (FP2) and 99999 in high resolution mode (if available). If the
measurement value is totalized, there is some danger of over-ranging the
output limits, as shown in the following example:
Example
Assume that daily total flux is desired, and that the datalogger scan rate is 1
second. With a multiplier that converts the readings to units of kJ m
-2 and an
average irradiance of 0.5kWm -2 , the maximum low resolution output limit will
be exceeded in less than four hours.
