The field measurements were carried out with ATLAS 350, a DC resistivity meter designed and developed by the authors of this paper.
Expired O2 and CO2 gas concentrations were measured using a mass spectrometer ARCO-1000AA, ARCO SYSTEM, Chiba, Japan), and gas volume was measured using a dry gas meter (DC-5C Shinagawa Seiki, Tokyo, Japan).
We designed and constructed the experimental device of 200-meter superconducting DC cable system in the beginning of 2010 and did the first experiment until March , 2010 and the second experiment has been done from August to October 2010.
Explained by Riew, "DC offers placard users free metered parking for twice the time limit, while Chicago makes placard users pay for metered parking and offers no time extensions.
Later, we walked six blocks back to Cuba's towering capitol building (a knockoff of ours in Washington DC -- but, they boast, "one meter taller").
Set the meter to the largest DC current range (at least 10 Amperes; this may involve plugging the probe wire to a different jack in the meter).
If the circuit to be tested is AC but the meter will only measure DC amps (or vice-versa), stop.
Keep in mind that some appliances or cord connected devices (see below) may have very high resistances to DC (the battery in your ohm meter) or, may need to be powered to complete circuit.
Now all 17,000 metered spaces in Washington, DC offer the pay-by-phone option, allowing DDOT to collect parking fees more efficiently and drivers to venture far from their car without having to run back and feed the meter.
100 V DC current is applied to a 3-meter-long soil column by electrodes connected to the soil.
