2.6.2.5 Discharge Time
Accepts entry of a discharge time between 0 and 300 seconds in 1 second intervals. This
is the time when the test voltage is removed and the device under test discharged. The
CAUTION HIGH VOLTAGE lamp goes OFF at the end of the programmed interval and
the last measurement result is retained on the display (unless no display is selected).

Figure 2-12: Measurement Mode Selection
Allows selection from two different modes of operation, Auto or Manual measurement.
In Auto the user presses [START] to initiate the entire test cycle automatically. The first
phase of the cycle is charge time, during which the device initially charges up to the
applied test voltage. The second phase is dwell, or time of electrification, during which
the device is fully charged but prior to a measurement. The third phase is measure time
during which measured results are displayed. The fourth and last phase is discharge time
during which the voltage is removed and the device allowed to discharge.
In Manual, test cycle timing is under complete user control, [START] must be pressed to
initiate the charge and measure phase and [STOP] pressed to discharge the device.
