Appending or overwriting existing reading buffers
When storing data to a reading buffer that already holds data, the new data can be appended to the
reading buffer data, or it can overwrite the old data.
To configure the instrument to append or overwrite measurements the next time data is
acquired:
1. Press the CONFIG key.
2. Select STORE, and then select STORAGE-MODE. The Storage Mode menu is shown.
3. Select one of the following:
â–ª APPEND
â–ª OVERWRITE
4. Press the EXIT (LOCAL) key to return to the main menu.
Storage operation
Use this option to initiate a storage operation and to configure the number of readings to acquire
during the storage operation. The reading count can be more than 60,000 if timestamps and source
values are enabled. The count can be more than 140,000 if timestamps and source
values are disabled.
To store the maximum number of readings in a reading buffer, disable the source values and
timestamps for that reading buffer.
To specify the number of readings and initiate the storing operation:
1. From the front panel, press the STORE key, and then select TAKE_READINGS.
2. Use the navigation wheel to select the number of readings.
3. Press the navigation wheel to switch to edit mode.
4. Turn the navigation wheel to change the numeric value.
5. Press the navigation wheel to save the numeric value.
6. Press the ENTER key to save the count.
7. Press the OUTPUT ON/OFF control to start making readings.
If the output-off mode is ZERO or the output is already on, the instrument starts acquiring readings
when the ENTER key is pressed. Otherwise, the instrument starts acquiring readings when the
output is turned on.
