1. MEASURING DC CURRENT: DC CURRENT MEASURING to measure DC voltage in principle not will look with air conditioning.Just to note the cable plug gauge should be attached/taped on the pole of the voltage source. Measurement steps are: 1) the note Limits measure, Pencolok red (+) and black (-) pencolok, positive pole (+) and (-) poles of negati. 2) Point switch point to DC volts. Measurements carried out in the State current flows (dynamic measurement), Switch on the number 10. 3) time hold the measurement, plug the Red (+) placed on the plug (+) and black (-) placed on (-). 4) that read is a scale of 0-10. For example pointing this means 1.5, voltage current = 1.5 volts. If we switch point at number 50, then the read switch scale 0-50.
