9.6 Storing Numeric Data
Explanation
When storage is in progress
9-14
Before you can start storing numeric data, you must set the storage mode, store count,
store interval, and the scheduled storage start and end times. This section explains how
to start and end storage. For instructions on how to set the storage mode, see section 9.2.
For instructions on how to set the store count, store interval, and storage start and end
times, see section 9.4.
Storage-Related Display Indications
When storage is started or stopped, the storage condition and store count appear at the
left of the screen.

Store condition
Starting the Storage Operation
• Storage will start under different conditions depending on the storage mode (see
section 9.2 for storage mode details). For details, see the storage start instructions
earlier in this section.
• You cannot start storage if the storage operation has not been reset.
• You do not need to reset the storage operation the first time you start storage after
turning the power on.
Stopping the Storage Operation
• You can use the STORE key to stop storage manually.
• Storage will stop under different conditions depending on the storage mode. For
details, see the storage stop instructions earlier in this section.
Resetting the Storage Operation
After you have stopped storage, you must reset the storage operation in order to start
storing again.
How Numeric Data Is Stored
Numeric data is either stored to USB memory or to the internal RAM disk. When you turn
off the WT500 power, the contents of the internal RAM disk are lost. If you choose to
store numeric data to the internal RAM disk, save it to USB memory before you turn off
the WT500.
Note
• During storage, no icons appear to indicate that storage medium is being accessed.
• For items with no numeric data, "NAN" (no data) is stored.
• When integration is not taking place, the integrated value will be stored as "NAN" (no data),
because no integrated value exists. The integration time will also be stored as "NAN" (no
data).
• The maximum harmonic order that can be stored is determined by the maximum harmonic
order set in the harmonic measurement (option) menu. For harmonic orders with no numeric
data, "NAN" (no data) is stored.
• If you hold the display by pressing HOLD during storage, the numeric values when you
pressed HOLD are stored. However, during integration, values being measured are stored.
• If the store interval is set to 00:00:00 and you hold the display by pressing HOLD during
storage, storage stops. Storage does not stop during integration.
