warming up the transducer for 3 minutes

using output monitoring meter V1 to measuring the output
of signal power source instrument, set a any input value
which is within the measuring range of the transducer Ur.
(for e.g. if input value is 100V, the output is 5V, the
expected output value Ug should be calculated as:
Ug = 5V
×
Ur/100V
