optionally switch ON displaying of MIN/MAX values on the LCD
reset memory of MIN/MAX values (if needed)
check free space in data memory, optionally erase data memory of the logger
enter password if protection against unauthorized manipulation with the logger is necessary
Logging interval between to subsequent measurements is specified by the user. Memorizing of
the first value is synchronized with the internal real time clock, so the logging is performed at sharp
multiples of minutes, hours and days. E.g. after starting the logging with the 15 minute interval the
first value is not stored immediately, but after the internal clock gets the status of a quarter, a half or
a whole hour. After starting the logging with the 3 hours interval the first value is stored at that
whole hour to perform the storing also at 00.00, i.e. at the beginning of the day. First storing is
performed at 00:00:00, 03:00:00, 06:00:00 hours, etc. - at the hour from the above nearest to the
logging start. After communication with computer or after start by magnet logger automatically
waits for the nearest whole multiple of time and then first measurement is performed. This is also
necessary to take into account when setting time of automatic logger switch ON.
Connect external temperature probes only to switched OFF logger, otherwise incorrect values
to data memory and min/max memory could be stored.
Notice:
If logger operates as permanently connected to the computer, using of magnet start/stop
is disabled.
To enable the logger control by magnet is suitable only in cases, when possibility of
unauthorized manipulation to the logger operation is eliminated.
If logger is controlled by binary signal from channel 4, logger will be switched OFF with the
delay up to 10s after appearance of desired binary state!
Reading on the display in usual operation (logger switched ON)
After switching ON the logger all LCD symbols are displayed for checking
the display.
Then actual date and time in logger is displayed for approximately 4 s.
Consequently reading of estimated remaining battery capacity for
approximately 2 s is displayed (values 0 to 100%). It is valid if logger is
operated at temperature from -5 to +35°C. If logger is operated often outside
of the above temperature range battery life can be reduced to 75%, i.e. if
displayed remaining battery capacity drops below 25%, it is recommended
to replace the battery.
If display is switched ON
, actual reading of measured values is displayed -
channel 1 temperature (°C 1) at the LCD upper line, channel 2 temperature
(°C 2) at the LCD lower line. Symbol LOG indicates data logging in
progress – if it blinks, data memory is filled up to more than 90%.
Other measured or calculated values are displayed always after 5 seconds.
Instrument now displays channel 3 temperature (°C) and binary input actual
state. Symbol On indicates closed contact (respectively low voltage level),
symbol OFF indicates opened or not connected contact.
