Compared to the 34401A DMM, Truevolt DMMs offer expanded
current ranges from 100 µA to 10 A. We have also added a temperature measurement function (RTD/PT100, 5 kΩ thermistor).
Additionally, diode measurement capability has been expanded
to allow a larger full-scale voltage to be measured (5 V) to
enable the measurement of more diode types such as LEDs.
