Storing and Recalling Data and Saving the Stored Data
Explanation
To store data, parameters such as the store mode, the store count, the store interval,
and the store reservation time must be specified before executing the operation. This
section explains the start and stop operations of storage. For the procedure on how to
set the store mode, see section 8.1; for the procedure on how to set the store count, the
store interval, and the store reservation time, see section 8.2.
• Display Related to Storage
When the storage operation is in the start or stop state, the storage state and store
count are displayed at the upper left of the screen.

• Starting the Storage Operation
• The storage operation starts according to various conditions depending on the
store mode (see section 8.1). For details, see the procedural explanation.
• The storage operation can be executed only when the internal memory is cleared.
• If you are performing the first storage operation after turning ON the power switch,
there is no need to clear the internal memory.
• Stopping the Storage Operation
• The storage operation can be forcibly stopped using the STORE key.
• The storage operation stops automatically according to various conditions
depending on the store mode. For details, see the procedural explanation.
• Initializing (Clearing) the Internal Memory
To start the storage operation again after stopping the operation, the internal memory
must be cleared.
• Retaining the Stored Data
The data stored to the internal memory cannot be retained by the internal lithium
battery. The data in the internal memory is lost when the power to the WT3000 is
turned OFF. To retain the data, save the data to the storage medium before turning
off the power.
Note
• [-------] (no data) is stored in places where there is no numeric data.
• If there are no integrated values because integration is not performed, [-------] (no data) is
stored. [-------] (no data) is also stored in places where there is no integration time.
• The maximum order for which the harmonic data is saved is the maximum harmonic order to
be measured that is specified in the harmonic measurement (option) menu. [-------] (no data)
is stored for harmonic orders without data.
• To store waveform display data, set the display mode to Wave, Numeric+Wave, Wave+Bar,
or Wave+Trend and display the waveform on the screen. If the display mode is not set to one
of these modes, “NAN” is stored for the waveform data.
• While the storage operation is in progress, you cannot change the PLL source, the equation
for distortion, scaling, averaging, filter, integration mode, integration timer, or the store
interval. In addition, you cannot change the auto print settings or execute auto print.
• If you hold the display by pressing HOLD while the storage operation is in progress, the value
that is present when HOLD is pressed is stored.
• If the store interval is 00:00:00 and you hold the display by pressing HOLD, the storage
operation stops.
