The TIME field for LONG shows the integration time of the long mode, which is calculated from the NPLC and power line frequency. You can change the NPLC value.

For details, see User’s Guide: Measurement and Analysis.

WAIT TIME For each unit, the 4155C/4156C automatically uses a wait time that depends on the

range value. This is the default wait time. In the WAIT TIME field, the value you specify is multiplied times the default wait time. Allowed values are 0.0 to 10.0 with

0.1 step.

The wait time is the time that a unit waits after forcing a value. During the wait time, the unit cannot start the measurement.

The default wait time is recommended. It is not easy to determine the best wait time. If you specify a wait time that is too short, the measurement may start before the output is stable. If too long, time will be wasted.
