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  channel  1 
temperature, arrow 2 for channel 2 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  after  displaying  of  all  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.
