Over-Range Indication
If over-range is indicated, the SL1400 may be receiving a voltage higher than
the observed waveform or measured waveform values. To prevent electric
shock, change the vertical scale with the RANGE knob so that the entire
amplitude of the waveform is displayed within the waveform display area, and
check the input voltage level.
Over-range indication
Indicates the number of the channel that over-range is occurring on.
If over-range is occurring on multiple channels, the smallest channel
number among them is indicated.
