1.
VOLTAGE - When measuring voltage, select voltage for type and adjust the
positions of the two cursors with the multipurpose control to measure V.
2.
TIME - When measuring time, select time for type and adjust the positions of
the two cursors with the multipurpose control to measure T.
The [CURSOR ] menu has two other modes: independent and tracking.
In the independent mode you can adjust the positions of the two cursors
