5.2.2 Observation Period, Measuring Time, End at Over-range,
Specifying Power, and Class Options
Menu
Use this menu for selecting a device operation type to set the observation period
(measuring time). The content is used for report printout. It does not directly affect
measurements.

Device operation types
Use this menu to set the measuring time. The setting range is 1 to 9600 seconds. Set
the value, in view of the operation cycle of the EUT and the device operation type
that is selected using the F1 key.
If you set the standard to JIS 2019/Ed2.0 or JIS 2019/Ed1.0, select Class C, and set
the limit values to 3rd/5th/Current Wave, the measurement time will be 0.2 seconds.
The Measurement Time setting will be disabled.
Page 5-46
If the measured value exceeds the set voltage range or current range (overrange), an
error message will be displayed and the measurement will be terminated. However,
the data up to the point when the overrange occurs can be analyzed. The judgment
will be FAIL.
Use this menu to specify how to handle the power value of the EUT. Select the
measured or specified value in the sub-menu. Enter a numeric value in the power
specification value (W).

Quasi-
Stationary
Tobs (observation period) to be set has a continuation period long enough to
satisfy a repeatability request to device operation type “Quasi-stationary.”
Short Cycle
Tobs (observation period) to be set has 10 or more fundamental cycles
and a continuation period long enough to satisfy a repeatability request to
device operation type “Short cycle.” It is very close to an integer multiple
of the device operation cycle.
Random
Tobs (observation period) to be set has a continuation period long enough
to satisfy a repeatability request to device operation type “Random.”
Long Cycle
Tobs (observation period) to be set is the total program cycle of a device to
device operation type “Long cycle” or 2.5 minutes that is typically assumed
as the operation period in which the maximum THC is generated.
