port it is necessary to use COM ADAPTER, for connection via USB port it is necessary to use USB
ADAPTER. Connect adapter connector to proper computer port and plug the adapter to the guide
slots on the side of logger.
Connecting logger to the computer by means of communication adapter
Notice: USB connector can be located also from the computer front side
After connecting the logger to the computer reading of logger info is enabled by means of the
PC software and also setting of the instrument accordingly to the user needs (menu Configuration /
Setting of instrument parameters). Before logging start it is necessary:

check or optionally set the logger real time clock
select suitable logging interval
select logging mode (cyclic or non cyclic)
switch ON the logger (or switch OFF, if it is about to be switched ON by magnet or
automatically with delayed start)
enable or disable the option to switch ON the logger by magnet
enable or disable the option to switch OFF the logger by magnet
enable or disable the option to clear minimum and maximum value memory by magnet
set date and time of logger automatic switching ON logger or disable this option
select if record runs permanently or only if alarm is active
If alarms are about to be applied, set both limits for each measured quantity and enable
alarm
optionally enable permanent alarm indication (alarm with memory)
switch ON or switch OFF display logger
optionally switch ON displaying of MIN/MAX values on the LCD
reset memory of MIN/MAX valueDs a(itaf Snheeeedte4dU).com
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
DataShee
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 6 hour 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 6.00,12.00, 18.00 or 00.00hour - 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.
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.
Reading on the display in usual operation (logger switched ON)
After switching ON the logger all LCD symbols are displayed for checking
the display.

Alarm indication on the display
It is necessary to enable alarm function from the PC and set for each quantity lower and upper
limit. If measured value is inside of set limits, alarm of proper quantity is not active. If value of
measured quantity gets outside of set limits, alarm of proper quantity is active and it is indicated on
the display. It is possible to select "memory alarm mode" when alarm is indicated permanently up
to reset from the PC.
Active alarm is indicated (if display is ON) by blinking of the value of
proper quantity on the display and arrow symbol appears at the LCD upper
side at the same time. Arrow 1 indicates active alarm for ambient
temperature, arrow 2 relative humidity and arrow 4 dew point temperature.
Notice: if logger is operated at low temperature (below approximately
-5 °C), alarm indication by blinking can be indistinct. Indication by arrows
works correctly.
Messages displayed on the LCD beyond usual operation
If measured value is out of the measurable or displayable range numeric
reading is replaced by hyphens.
If memory is totally full filled in non-cyclic logging mode, logger is
switched OFF and message MEMO FULL appears on the LCD. It appears
also if logger is operated with switched OFF display.

New initialization of logger can occur in switching ON the logger
(immediately afterDadtiasSplhaeyeitn4gU.ocfomall LCD segments for checking) e.g. after
replacement of totally discharged battery for new one. State is indicated by
INIT reading. It can be displayed for about 12 s.
If battery voltage drop occurred since last internal clock setting below
critical limit or battery disconnection for longer period than approximately
30 s, after display switch ON (during date and time display) all four arrows
appears as warning to check or set it again from the computer. However all
logger functions work without limitation.
If reading BAT is displayed periodically on LCD upper line (for 1 s with 10
s interval), the end of estimated battery life is coming – however logger
functions are not limited. Replace battery as soon as possible!
If reading BAT is displayed permanently, battery voltage is low and logger
is not possible to switch ON. If logger was switched ON before it, data
logging is stopped and logger is switched OFF. Communication
with computer can temporarily work. Replace battery as soon as possible!

Start / stop by magnet
The function must be enabled from the PC before. If only switching OFF by magnet is enabled,
it is of course necessary to switch ON the logger from the computer.
Notice: It is not possible to combine function switching OFF by magnet and MIN/MAX
memory clear by magnet! User software enables only one of them to select.
