Warning: To avoid false readings,
which could lead to possible electric shock
or personal injury, replace the battery as
soon as the battery indicator appears.
Indicates negative readings.
Indicator for ac voltage or current.
AC voltage and current are displayed as
the average of the absolute value of the
input,
calibrated to indicate the
equivalent rms value of a sine wave.
Indicator for dc voltage or current.
AUTO AUTO AUTO AUTO The Meter is in the Autorange mode in
which the meter automatically selects the
range with the best resolution.
