HPS50 PersonalScope TM Meter readout
Audio power calculation.
The measured voltage is converted into power,
suposing that the voltage is measured across an
impedance. The calculated power can be displayed
for loads of 2, 4, 8, 16 or 32 Ohm. To choose the
different loads, first highlight the power readout and
then press the right cursor key.
