Download time adjust data data
When the gACC-499E/U is connected directly to an encoder or a pulse generator of a gas meter, intervals
larger than 24 hours can be used. Because the clock deviation is approximately 1 second per day, a
correction value over the used interval will be determined automatically after synchronizing the clock.
When using an gAVC 1200 this does not apply because these are normally read once a day.
The "Download time correction data" function indicates the correction which is determind for each calendar
month and will be applied. The correction may vary per month because a different clock deviation can occur
which is caused by the influence of the average monthly temperature. A time will be stored in the register
which equals the number of milliseconds since 01-01-1970. 15 values will be stored corresponding to 14
monthly intervals. The correction will be applied to the days of the selected interval. If over a month a
deviation of 12.000 milliseconds is determined this will be corrected every day for 1/30 part. The correcting
will take place during the caching of the measurement data memory to the TCi65 memory.
After the read-out there will be referred to a directory where the correction data can be stored. The data will
be saved as a *.csv file.
