PART 2 DA264
Offset calibration value:
(H8000 to H8003)
At the factory shipment, the DA264 is calibrated for each output range. Therefore, there is no
need for user to calibrate normally.
However, depending on the usage condition, field adjustments are required. For this purpose,
the DA264 has the offset calibration function.
In the DA264, the D/A conversion is performed as follows.
When the offset calibration value is set, this value is added to the original D/A conversion data.
Then D/A conversion is performed in the DA264.
The data setting range of the offset calibration value are as follows.
