Logging mode
In logging mode measured values are stored to instrument internal memory. Memory is non
volatile, i.e. if battery voltage drops or battery is disconnected, stored data will not be lost.
Instrument can work in two logging modes:
automatic mode
- actual measured values are stored to memory in adjustable time interval. Storing
of the first value is synchronised with internal real time clock , so the memorizing is performed
at sharp multiples of minutes, hours and days. E.g. if the storing interval is 15 minutes value will
be stored each 15., 30., 45. a 00. minute and zero second in each hour, if interval is 3 hours
values will be stored in 00:00:00, 03:00:00, 06:00:00. etc. It means after starting automatic
logging instrument waits for the nearest integer multiple of time and then stores the first value.
manual mode
- actual measured value is stored after pressing ENTER key (instrument should be in
default mode of displaying actual measured values). Each storing is indicated by a short beep and
position of the record in memory is displayed (reading MEMO with the record serial number). In
this mode it is possible to store max. 1000 set of records.
It is possible to select one of the three logging modes (MODE):
- automatic non cyclic logging, when logging stops after fulfilling the memory. Reading MEMO
FULL is displayed (reading disappears after pressing any key)
- automatic cyclic logging, when after fulfilling the memory oldest data are replaced with new
values
- manual logging, designed for manual storing of measured values by ENTER key
Logging modes are not mutually compatible and after changing logging mode memory of the
instrument should be cleared.
Logging in progress will always be interrupted by instrument connection to the computer or
switching OFF the instrument by ON/OFF key. Logging in progress will be automatically stopped
if battery voltage below 7 V is indicated by the instrument. This prevents to log values effected by
low battery voltage.
Logging start from instrument keyboard
Start logging by confirmation of the menu item START (symbol Strt) by
pressing ENTER key.
Notice: it is not possible to start logging if low battery voltage is indicated.
Instrument offers the possibility to clearing the instrument memory (ERAS).
If you do not wish to clear the memory before new logging start, confirm
selection ERAS NO by pressing the ENTER key
Now instrument displays adjusted storing interval. To modify the storing
interval use arrow keys. Interval 10 sec is displayed as
MIN 0:10
, minute
intervals are displayed as
MIN x:00
and hour intervals as
x:Ho
. Confirm
adjusted interval by pressing ENTER key. Notice: if manual logging mode
is selected, this menu item is skipped (there is no interval adjustment).
Logging is started and instrument returns to default mode displaying actual
values. Logging in progress is in default mode indicated with reading LOG
on display. If memory is filled over 90 %, symbol LOG is blinking (only in
automatic logging).
