4. Software on HYDROCAL unit
4.1 General information
The gas-in-oil analyzer HYDROCAL1005 is based on a microprocessor controlled measuring sys-
tem. A 32 Bit „Coldfire“ processor with a clock frequency of 240 MHz (bus clock 80 MHz) is used.
The software has been developed with the language „C“. The system has a flash memory of 16 / 32 /
64 Mbyte for measuring data. This offers approximately 2 / 4 / 8 years time storage capacity for the
measuring data.
After this period, the oldest data will be overwritten by the latest values. When using additional exter-
nal sensors, the storage capacity depends on the number of sensors and the time interval selected
for storage. The following formula can be used to determine the storage capacity (in the example 64
Mbyte is used):

With one additional sensor with a time interval of 5 minutes the following calculation results:

Also an additional reduction of the storage time takes place by the definition of alarms. Each change
of alarm status requires 12 Bytes.
Attention: To avoid any loss of data, it is proposed to read out regularly
the measuring data by the Windows based software “HydroSoft”.
