The HF special in the 200uA DC-current mode has a 1k Ohm shunt or burden resistor. With no change in the circuit, they can switch the meter to DC-voltage mode which measures the voltage across 51k Ohms. Readings of 30-40 uAmps using the 200uA DC-current mode would instead be 1.5 - 2.0 Volts in the DC-voltage mode.
The reality as I see it is simple. It doesn't matter what units the meter is measuring (voltage, current, widgets, etc.); the readout gets larger and smaller proportional to the received 455 kHz signal. And all this occurs over a wide range making it a useful and remarkably inexpensive tool.
Yes, if I were doing it I'd prefer the Voltage measurement mode...but I'm not doing it. I'd say that ship has sailed and the standard has been set.
