heheheh... I learned how really bad those DVM POS's are when using one to measure in the vicinity of 1KW PDM power pulses. As expected, even one of my digital meters in the rig that measures current is way off.
Analog is the only way around big fields.
So in this case, basically you're using the meter as a field strength meter looking for unbalanced RF currents. Though, all of my rigs are open in the back and will probably give a stray RF reading there...
I have a rather expensive Fluke DVM. It works excellently for measuring dc and ac voltages and currents, and resistance. It has a capacitance function, but that scale is so far off as to be useless. My cheap little ECG capacitance meter reads right on, down to the picofarad and up to hundreds of mfd - just be sure the capacitor is completely discharged before trying to read the capacitance. The DVM is useless for measuring ground resistances. I tried using it to measure the DC ground resistance from one end of my beverage to the other. All I got was nonsense readings. No strong radio stations near here, so it wasn't rf. It turned out to be electrolytic action in the soil. I can measure a fraction of a volt DC between the beverage wire and ground with nothing else attached but the terminating resistor. For ground resistance readings I would recommend an analogue ohmmeter with low internal resistance (high current for the low resistance ranges), or better still, use several volts from a DC power supply and measure current, and then calculate the resistance using Ohm's law. AC might work better than DC, since the DC tends to generate electrolytic action between ground rods/radials and the soil, and the current reading may change rapidly as the voltage applied, and the metal ground conductors and soil start to act like a battery.
