OK Softkey: acknowledge instructions in the measuring sequence
Hard Keys
Sequence creation: select measurement step (1 to 10)
STORE Sequence creation: transfer the measuring function to the sequence,
Sequence run: save the measured value for the current measurement step by 
pressing the hard key at the multimeter or on the Z270S probe 
(METRAHIT IM XTRA BT and METRAHIT IM E-DRIVE BT only).
OK Sequence run: end the measurement step.
