9 Data Logger:
As soon as key "Store" (key 6) is pressed and ‘Func = Stor’ was chosen a data set will be stored.
The data stored can either be observed on the display (prt. "How to Display Individual Values" below), or be read
into a PC via the interface.
When ‘CYCL’ is set and the logger has been started using key 6 (press for 2 seconds), data sets will be stored till
the recording is either stopped or the logger memory is full.
The logger cycle time can be set. Use the interface to input the data stored into a PC.
9.1 Storing of Individual Values: "Func Stor"
Data set that can be stored: 99
One data set consists of: measuring value CH1, measuring value CH2, measuring value DIF and time + date
Press "Store"-key to store current values. .St.XX. will be displayed for a short time, XX representing the number of
the data set 1..99.
Upon pressing the "Store"-key (key 6) for 2 seconds the selection for deleting the logger memory will be displayed
assumed that there are any logger data.
delete all data sets
delete data set recorded last
do not delete (= cancel procedure)
Use the keys "" (key 2) or "" (key 5) to make a selection. Use key "Quit" (key 6) to acknowledge selection.
If the logger memory is full a warning will appear on the display:
(warning triangle permanently shown, cyclic display of "LoGG FuLL" and the current measuring value)
9.2 How to Display Individual Values
Individual values can also be displayed without interface which is not possible with the cyclic logger function.
If there are data sets in the logger memory, the additional main menue .rEAd LoGG. will be offered upon call-up of
the menu (press key "Set" (key 4) for 2 sec).
When the ""-key (key 3) is pressed the last data set will be displayed. Use ""-key (key 3) to change over be-
tween the values of one data set (CH1, CH2, DIF, date/time).
To change over from one data set to another use the keys "" (key 2) or "" (key 5).
9.3 Cyclic Logger Function: "Func CYCL"
Data sets that can be stored: 9999
One data set consists of: measuring value CH1, measuring value CH2 and measuring value DIF
The cycle time is set during ’Device configuration’.
Start logger recording:
Press "Store"-key (key 6) for 2 seconds to start recording. Then .St.XXXX. will be displayed for a short time for every
logging;
XXXX representing the number of the data set 1..9999.
If the logger memory is full a warning triangle will be shown on the display:
(warning triangle permanently shown, cyclic display of "LoGG FuLL" and the current measuring value)
Stop logger recording:
Press "Store"-key (key 6) for a short time to stop recording. You will then be asked to acknowledge again:
recording to be stopped
recording to be continued
Use the keys "" (key 2) or "" (key 5) to make your selection. Use "Quit"-key (key 6) to acknowledge your selec-
