Instruction Manual for use of S0541 logger  

 

Instrument  is  designed  for  measurement  and  record  of  temperature  from  two  external 

temperature  probes  and  two  external  voltage  signals  0-5Vdc.  Temperature  probes  and  voltage 
signals are connected by means of connectors. Measured value of temperature and actual values of 
voltage  inputs  are  displayed  on  dual  line  LCD  display  and  are  stored  in  adjusted  time  interval  to 
internal  non-volatile  memory.  All  logger  settings  and  control  are  performed by means  of personal 
computer and password protection is enabled. It is also possible to switch ON and switch OFF the 
logger by start/stop magnet (this function can be disabled from the PC). Also automatic switch ON 
at programmed day and time (maximum one month forward) is enabled. Start/stop magnet enables 
also to clear the minimum and maximum value memory. Minimum and maximum measured values 
can be displayed (display switches to actual measured values and min/max values automatically). It 
is  also  possible  to  operate  logger  with  switched  OFF  display.  Short  display  of  actual  measured 
values is enabled by means of magnet. 

Switched ON logger every 10 seconds (independently on logging interval) updates MIN/MAX 

memory, compares measured values of each channel with two adjustable limits for each channel and 
exceeding  of  limits  is  indicated  on  the  display  (alarm  function).  Also  memory  alarm  mode  is 
selectable, when alarm is indicated permanently till alarm memory reset. Alarm function is enabled 
or disabled for each channel individually.  

Logging  mode  can  be  adjusted  as  non-cyclic, when logging stops after filling the memory. In 

cyclic mode oldest stored values are overwritten by new. In addition logging mode can be selected 
when logging is active only if measured value is out of adjusted alarm limits. 

Stored  values  can  be  transferred  from  logger  memory  to  the  PC  by  means  of  communication 

adapter. Communication adapter can be connected to the logger permanently  – data logging is not 
interrupted even if data download appears.  

Logger evaluates minimum battery voltage and its drop below allowed limit is indicated on the 

display.  At  the  same  time  value  of  remaining  battery  capacity  is  available  by  means  of  the  PC 
program and appears on the logger LCD in % (every time after switch ON). 

  

Technical parameters: 

 

 
External temperature probes (can be limited by concrete applied probe):  

Range of measurement: -90 to +260 °C (RTD Pt1000/3850ppm probe) 

  -50 to +150 °C (RTD Ni1000/6180ppm probe) 

   

Resolution: 0.1 °C 

   

Accuracy temperature inputs without probe (Pt1000 and Ni1000): 

±0.2 °C from -50 to +100 °C 
±0.2 % from reading from +100 to +260 °C 
±0.4 % from reading from -50 to -90 °C 

Accuracy of the instrument with connected external probe is defined by above input 

accuracy and the accuracy of connected probe. 

Type of compatible probe: based on RTD Pt1000/3850ppm or Ni1000/6180ppm equipped  
with ELKA3008 female connector 
Recommended probe Pt1000TG8/E (IP67, -80 to +200°C) 
Response time of N1ATG8 probe (air flow approximately 1 m/s): 
  t63 < 1 min, t90 < 3 min (temperature step 20 °C) 
Voltage inputs (IN3, IN4): 

Range of measured voltage: 0 to 5 V dc 
Effective resolution: 13 bits 
Measurement accuracy: ±0,2 % FS 

Input resistance: approximately 100k Ohms
