4.- INSTRUCTIONS
With this meter we can check the battery status. If one battery
have not enough energy, you will see "LOBAT" or "BAT" in the
LCD screen. The symbol ¡ indicates that the voltage or the
current must not exceed the indicated values. It is used to
prevent damages in the internal circuits. Before to measure, we
should choose the correct range.
MEASURING DC / AC VOLTAGE
1.- Connect the red testing point to the jack signaled "V Ω" and
the black testing point to the jack signaled "COM".
2.- Set the dial to the VDC / VAC setting . If you see "1" in the
display, it means the measured voltage exceed the selected
range. Please, select a higher one.
