in color and 0.3 inches in height, which shows the
selected values and the corresponding units to the
selected parameter with three lightning indicators
located to the right side of the display.
There are two different parameters available:
•
Voltage (V).
•
Current (A).
In current and voltage, depending on the selected range, the decimal point will adjust
automatically. The V and A indicators will light up automatically when selected.
When the value in the display begins to flash, it indicates that the value selected and is not
in the output.
