Over-Range Indication
If over-range is indicated, the DL850/DL850V may be receiving a voltage higher than the
observed waveform or measured waveform values. To prevent electric shock, change the
vertical scale with the SCALE 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.
Channel indication when over-range is occurring on multiple channels
Indicates the smallest number among the channels that over-range is
occurring on.
