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.
Device 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 synchronized 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 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 device 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.
