Over-Range Indication
If over-range is indicated on the display of SL1000, the SL1000 may be receiving
a voltage higher than the observed waveform or measured waveform values. To
prevent electric shock, change the measuring range so that the entire amplitude
of the waveform is displayed within the waveform display area of the SL1000
Acquisition Software, and check the input voltage level.
Range Out Slot1_L >>
Channel
U: Upper channel of the slot
L: Lower channel of the slot
Slot No.
Indicate “>>” when over-range is occurring on multiple channels.
Indicates the smallest number among the slot
that over-range is occurring on.
