Fig. 5.10 Measured Data Buffer Clear Screen
On this screen, the function of the function key [F5] changes to EXEC.
Press the [F5] EXEC key to clear data.
(a) [
◄
] and [
►
] keys
The keys set an area for data clearing.
ALL: All data erase
LMT: Clearing of data in a specified area (Deletes data in the range
of SADR to EADR)
(b) [
▲
] and [
▼
] keys
Select an item for start No. SADR and end No. EADR when the clearing
range is LMT.
Input a data No. within the specified range operating the numeric keys when
setting SADR and EADR. Press the [ENTER] key to enter the input.
(c) Press the [F5] EXEC key to clear data.
(d) Press the [ENTER] key to return to the Function Selection screen. (See Fig.
5.21)
(4) Data buffer usage
The data buffer is useful such as when analyzing data after taking
measurement.
Measurement can be performed relatively quickly if data is fetched collectively
after finishing all measurements since fetching of data for each measurement is
time consuming such as when fetching data using an interface.
Take measurement after erasing data in the data buffer when using the buffer.
Otherwise data separation point cannot be determined because previous data is
still remaining.
Changing the measuring mode during measurement while using the data buffer
disables distinction between saved data and new data.
All data is saved in the buffer in measured current values and is displayed after
converting to a format matching the measuring mode when data is displayed.
Values sometimes cannot be displayed correctly if the measuring mode during
display differs from the measuring mode used during measurement.
