Display
Readings are shown on a liquid crystal display (LCD).
Symbols on the display indicate what the meter is doing.
See Figure 3 and Table 2.
If a measurement is too large to be displayed, OL (over-
load) is shown on the display and the whole bar graph
lights.
Warning
To avoid false readings, which could lead to
possible electric shock or personal injury, re-
place the battery as soon as the battery indi-
cator (N) appears.
