Logging Every reading (All)
With the period set to All
{ALL}
, the timer is inoperative and readings are stored after every
measurement, i.e. at the measurement rate of 4 readings/sec or 20 readings/sec dependant on
mode and measurement speed setting. To select All, first set the period to Off (using the shifted
key Clear
[Shift] [Auto]
) and press
[v]
. Confirm with
[OK]
.
Logging from the Timer
To engage the timer starting from Off or All, press the Navigator Up key once or twice
respectively. The display will show 0001 representing a timer period of 1 second. This can be
changed to any value up to 9999 seconds using the Navigator keys (
[<]
/
[>]
to select the digit
and
[
ଢ଼@
/
[v]
to change the value). Confirm with
[OK]
.
Multiple Trigger Sources
A reading is logged in response to any valid trigger source. Thus, for example, the timer can be
set to log at fixed intervals and additional intermediate readings logged by pressing
[Man Log]
, or generating an external trigger command.
11.2
Running the Logger
Once the logger has been set up as described above, confirmation of the period will return the
secondary display to flashing the word
{run}
. Pressing
[OK]
at this point will start the logger
running.
The reading number is shown in the secondary display (001 to 499). When the maximum
number of readings is reached the display shows
{FULL}
. If the logger has existing readings
stored, new readings will commence at the next available store number.
Note that all logging sources are OR’ed so that, the timer (if active), manual logging key, trigger
input, or remote interface command can all cause a measurement to be stored.
11.3
Starting and Stopping the Logger
Logging can be paused by pressing
[Stop]
. This returns the display to show a flashing
{run}
and logging can be resumed by pressing
[OK]
. Alternatively logger Edit, Recall or Clear can be
selected at this point.
When paused, no measurements, and no change to the measurement parameter or range, can
be made. To make changes or view the measurement without logging, the function must be
exited by pressing
[Function]
. Logging can be restarted by pressing
[Function]
and then
pressing
[OK]
twice.
11.4
Recalling Logger Readings
Logger readings are held in non-volatile memory until cleared, and can be viewed at any time.
To recall readings to the display, select the logger function and use the Navigator keys to select
{rECALL}
. Confirm with
[OK]
.
The last viewed logger position is shown in the secondary display with the associated
measurement reading in the main display. Use the Navigator keys to scroll through the
readings.
11.5
Clearing Logger Readings
To clear the contents of the logger, select the logger function and use the Navigator keys to
select
{CLEAr}
. Confirm with
[OK]
. The secondary display will show
{nOnE}
and all logger
entries will be cleared. It is not possible to clear individual logger entries.
Once cleared, the logger will commence from position 000 when run.
