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.
