Operation

The user can continue tuning the DAC until precise output is

obtained by changing the count value and pressing ENT. Once the

calibration is done press the "save calibration value" option to write this

value into the memory.

Once the low limit value is saved the screen will move to tuning of

Range 20mA output. This screen provides similar functionality like the

previous screen but this time the adjustment is for the high limit, 20 mA.

Press the count option to tune the DAC like in 4mA case. In the

edit screen you can change the value and press ENT to write the DAC

with the new value. User can verify this by measuring the output of the

DAC using a multimeter.

Note: The limits of the counts for the DAC are from 0 to 65535.

The counts for 4.0 ma by default are set at 10922. The

counts for 20.0 ma by default are set at 54613.
