from AC to DC to AC+DC.
The coupling is indicated in the multimeter window of the channel concerned.
When selected for ohmmeter, continuity or capacimeter measurements,
component testing or temperature measurements on channel 1, the key has no
effect, as the input coupling in these functions cannot be adjusted.

If the autorange mode is activated, the manual adjustment has no effect: the
autorange will automatically reset the instrument to the measurement range
best suited to the input signal.
