11.D/A CONVERTER
96
Example of setting
In the case where:
D/A output mode.............0 (linked with indicated value)
D/A zero setting ..............00500
D/A full scale setting ......02500
11-2-3. About D/A Resolution
The resolution of the D/A converter is 1/10000 with respect to 4 to 20mA.
In other words, the minimum unit of voltage is:
(20 - 4mA) × 1/10000 = 1.6µA.
Also, the minimum unit of indicated value is:
(D/A full scale set value - D/A zero set value) × 1/10000.
