Battery replacement 

Low  battery  is  indicated  on  the  display  by  blinking  of  reading  "BAT".  It  can  be  displayed 

permanently,  if  battery  voltage  is  too  low.  Replace  the  battery  for  new  one.  If  logger  is  operated 
often  in  temperature  below  -5°C  or  over  +35°C  and  PC  program  indicates  remaining  battery 
capacity below 25% it is also recommended to replace the battery. Applied is Lithium battery 3.6 V, 
size AA. Battery is located under logger lid. 

Warning:

  near  battery  fragile  glass  reed  contact  is  located  –  be  careful  not  to  damage  it.  Be 

careful in battery replacement! 

 

Replacement procedure: 

 

switch off the logger by the PC program or by magnet (if low battery allows) 

 

unscrew four corner screws and remove the lid 

 

remove old battery by pulling the glued tape 

 

insert new battery 

respecting the correct polarity

 (see s and – near battery holder). If 

you  connect  new  battery  up  to  30  s,  all  logger  settings  remain unchanged. In the opposite case 
check by means of PC program all settings, especially the real time clock in logger. 

Attention, 

inserted battery with incorrect polarity causes logger damage!

 

 

put the lid back again and screw four screws. Be careful to have the rubber sealing properly in the 
slot and tighten the screws properly to ensure the water resistance of the instrument. 

connect  logger  to  the  computer  and 

write  to  it  the  information  on  battery  replacement 

(menu Configuration/Battery replacement). This step is necessary to evaluate properly the remaining 
battery capacity. 

 

Old battery or logger itself (after its life) is necessary to liquidate ecologically! 

 

Connection of female ELKA 3008V connector for temperature probe and binary contact 

It  is  possible  to  order  as  an  optional  accessory  connector  for 

connection of temperature probe. Signal cable should be shielded, round 
cross section of minimum diameter of 3.5 mm and maximum diameter of 
5 mm, maximum length of 10 m and as large as possible cross section of 
cords  (stranded  wires).  Outer  diameter  must  be  from  1  to  1.55  mm 
including  insulation.  Connect  connector  to  temperature  signal 
accordingly  to  the  figure  by  means  of  the  manual  included  in  delivery. 
Choose  the  most  suitable  plastic  insert  accordingly  to  the  diameter  of 
stranded  wires  of  the  cable.  The  IP67  protection  is  guaranteed  only  if 
connector is assembled correctly! 

It  is  necessary  to  select  and  connect  cable  for  binary  inputs  with 

respecting  the  same  rules  as  above.  Connect  the  contact  instead  of  the  RTD  probe.  Due  to  high 
impedance of binary inputs it is necessary to avoid places with higher electromagnetic interference 
when installing cables from contacts (switchboards, motors, contactors, frequency converters, etc.) 

 

Instrument passed through tests of electromagnetic compatibility (EMC): 

 

Device conforms in accordance with EN 61326-1 these norms: 

 

radiation:  

EN 55011 Class B 

 

immunity:  

EN 61000-4-2 (levels 4/8 kV, Class A) 

 

 

 

EN 61000-4-3 (intensity of electric field 3 V/m, Class A) 

 

 

 

EN 61000-4-4 (levels 1/0.5 kV, Class A) 

 

 

 

EN 61000-4-6 (intensity of electric field 3 V/m, Class A)
