A.1 Analog Output
Note [1]: Due to calibration mechanism, a tiny range (< 0.02% of full-scale range)
near maximum or minimum output range may be clipped. This will be observed, for
example, when output voltages are in the range of -9.99756 V to -10 V (for ±10 V out-
put range) but the actual values are all -9.99756V.
