3.2  „Func-CYCL“: Automatic Recording With Selectable Logger-Cycle-Time

The Logger-Cycle-Time is settable (p.r.t. Configuration). For example „CYCL“ = 60: A measuring is recorded
after each 60 seconds.
When the slow measurement "rAtE-Slo" is chosen, additionally a low power function is available: „Lo.Po“.
If „Lo.Po“ is on, the device only will take a measurement at the point of time of the recording. In between the
recordings the measuring shuts down. This decreases the power consumption enormously and therefore is
recommended e.g. for long time recordings where no mains adapter is available.

Max. number of measurings: 10000
Cycle time:

1...3600 seconds (=1h), selectable in the configuration

A measuring contains:

!

  slow measuring rate (rAtE Slo):

- current measuring value at the time of recording
-  min peak, max peak since the last recording

!

  fast measuring rates (rAtE FASt,P.dEt):

- arithmetic mean value since the last recording
- min peak, max peak since the last recording

Starting a recording:

By pressing "Store" (key 6) for 2 seconds the logger operation will be called. The display will show: 

By pressing "Store" again the recording will be initiated.

After that the display shows ‘St.XXXX‘ for a short time whenever a measuring is recorded. XXXX is the
number of the measuring 1... 10000.

If the logger memory is full, the display will show: 

 The recording automatically will be stopped.

If Low-Power-Logger-Function „Lo.Po = on“ the device switches itself off as soon as the memory gets filled.

Stopping the recording manually:

By pressing "Store" (key 6) the recording can be stopped manually. Then the following choice appears:

 

The selection can be made by 

5

 (key 2) and 

6

 (key 5). "Quit" (key 6) enters the choice.

Note: 

If you try to switch off the instrument in the cyclic recording operation You will be asked
once again if the recording is to be stopped.
The device can only be switched off after the recording has been stopped!
The Auto-Power-Off-function is deactivated during recording!

Clear Recordings:

By pressing "Store" (key 6) for 2 seconds the logger operation will be called.

The display will show: 

 By pressing the keys 

5

 (key 2) or 

6

 (key 5) the display will change to 

.

When „Store“ is pressed, the choice for clearing the logger memory will be displayed:

Clear all recordings

Clear the last
recording sequence

Clear nothing
(cancel menu)

The selection can be made by 

5

 (key 2) and 

6

 (key 5). "Quit" (key 6) enters the choice.

Stop the
recording

Do not stop the
recording
