The specifications listed in the following table are based on an instru-
ment operating in an ambient temperature of between 65 and 90˚F, at a
relative humidity of less than 80%, and within one year of calibration.
The “accuracy” column indicates the percent of possible error based on
the reading displayed, plus an additional allowance for error based on
the value of the least significant digits of the selected range. This is stat-
ed as (±X% + X dgts).
AC readings displayed on this meter are average responding, True-RMS
indicating. They are based on a true sinusoidal waveform.
