4.1 Measurement Value Display Procedure
48
The valid measurement range (the range of guaranteed accuracy) is 1% to 110% of the full-scale range
(except that valid voltage is limited to 1000 V in the 1500 V scale).
The display range of this unit is between the zero surpress level to 120% of the measurement range.
The following display indicates over-range measurement.
If input at or below the zero suppress setting for the measurement range is measured, the measured
value will not change from zero. To display even low input levels, turn off the zero suppress setting or set
it to 0.1%.
See Zero surpress level: OFF (initial setting), 0.1%f.s., 0.5%f.s. (p. 129)
Peak Over indicators light when an input voltage or current waveform peak value exceeds three times the
full-scale range (except the 1500 V range, when the voltage exceeds ±2000 V, see the figure below). The
indicators are shown on all screens, so that Peak Over can be seen even on channels not currently
selected.
Example: The following display indicates that the CH 1 voltage and CH 3 current are at Peak Over levels.
