Dual Input Meter
The accuracy of all measurements is within ± (% of
reading + number of counts) from 18 °C to 28 °C.
Add 0.1x (specific accuracy) for each °C below 18 °C or
above 28 °C. For voltage measurements with 10:1 probe,
add probe uncertainty +1%. More than one waveform
period must be visible on the sceen.
