If numerical values are hard to read
Right-click and select [DISP] to enable display selection. You can display the wave-
form and numerical values separately.
See: "6.7.3 Switching the Waveform Display Width" (p.135)
To view the waveform before or after the A/B cursors when these are off the
screen
When using the A/B cursors, the waveform at an off-screen cursor location can be dis-
played using the Jump function.
See: "6.3.3 Moving the Position" (p.126)
If A/B cursors are activated but do not show up on screen
The position of the A/B cursors can be checked on the scroll bar.(p.125)
If the cursor type is [div] or [Trace] cursors, cursor measurements can be made even
if the A or B cursor is off-screen.

• When Using External Sampling: Value t is the number of samples.
• The data measured with MR8990 Digital Voltmeter Unit is updated at each of
the two movement points of the A and B cursors.
• When the voltage range is changed during measurement by the recorder func-
tion: Trace measurement values are acquired at the range settings when mea-
surement was stopped.
