MEASURING AC & DC VOLTAGE
Voltage means the difference in electrical potential between two points. The
polarity of AC voltage varies over time, while the polarity of DC is constant
over time. The meter displays ac voltage values as rms (root mean square
readings. The rms value means the equivalent dc voltage that can produce
the same amount of heat in a resistance as the measured sinewave
voltage.
How to measure : First, press , the voltage measuring button, and then
select AC or DC by pressing In case of DC to be measured, place the
red lead on + point, and the black lead on - point, each on the voltage source.

MEASURING AC & DC CURRENT
Current is simply defined as a flow of electrons running through a
conductor. To measure current, you must break the circuit under test, and
then place the meter in series with the circuit. The current measuring range
of the meter is 10A max.
How to measure : First, turn off the power of the circuit, and, discharge
the high voltage capacitor. Fix the red lead into the terminals of mA and
10A in accordance with the value to be measured. Select one of the buttons
& . When & are selected, place the red lead on
mA, and When button is selected, place the red lead on 10A.
