Current range switching when output is enabled

[prasimix]

When load is connected and channel output is enabled when current autorange is active a possibly unnecessary switching between low current ranges is happened that introduce additional ~30 ms delay before steady state is reached. That can be seen in both CV (first fig.) and CC (second fig.) mode. CURRENT_AUTO_RANGE_SWITCHING_DELAY_MS is set to 5 ms (default).

This is happened occasionally and maybe depends of ADC cycle.

It seems that switching "pattern" depends of set output voltage, current and connected load. The following figure shows another possible pattern (U_SET=5 V, I_SET= 2 A, Load= 2 Ohm, CC mode):

Fixed, current range change due to autoranging from OFF to ON state with load connected now looks like this (CC mode):

Even in ON state when load is applied change looks better (CC mode, same U_SET and I_SET)):
