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.
