Click the [Mode] box, and then choose a measurement mode from the list.
Voltage
Measures a waveform in voltage mode.
Temperature Measures a waveform in temperature mode.
Selectable modes vary depending on the installed modules.

Click the [Range (f.s.)] box, and then choose a measurement range from the list.
Select a measurement range for each channel. The value of the range represents its maximum displayable
value (f.s.).
See the following table for the full-scale resolution of each module.
If the input voltage exceeds the measurable range (overrange occurs), change the measurement range to one
with a lower sensitivity.
For Model MR8990 and Model U8991, starting a measurement using a high-sensitivity range with the input
terminal open causes an input signal to be overrange.
After changing the measurement range, check values of the level, upper limit, lower limit, and other values of
the trigger, search, and numerical calculation functions.
