The SI prefixes (k, M, etc.) that are placed before units of measurement and the scales they represent are a
(10

), p (10

), n (10
-9
), µ (10

), m (10

Measurement accuracy (fixed range)
Measurement accuracy Relative ac Calibration accuracy
Relative accuracy ± (| Basic accuracy | + | Dynamic accuracy | + | Inter-range accuracy × N|),
where N is | number of measurement range steps between channels |.
Example: If the measurement ranges of each channels are 300 Vrms and 1
Vrms, N is 5 (300 V to 100 V to 30 V to 10 V to 3 V to 1 V).
Calibration accuracy The accuracy of external equipment that is connected to the instrument, such
as a shunt resistor or probe, or the accuracy of the calibration standard
equipment.
Basic accuracy Upper: gain (ratio); Lower: phase

Conditions: At least 30 cycles of integration, fixed measurement range for both channels, and
both channels have the same range. The gain and phase error for when the signal
input is at the full scale of the measurement range for both channels.
*For the cells that contain only "–", the measurement range exceeds the maximum input voltage (see
"
9.2 Analysis input section
, ● Maximum input voltage"), so either the measurement is not possible
or there is no accuracy specification for it.
