Carrier 500 T/R Manual De Usuario

 
 

 
If the display shows one of the following values: 
 
OC 

(I)  

the input is activated but no sensor is connected. 

(ii) 

the sensor has an open circuit (sensor or wire failure.) 

 
SC 

(I)  

the sensor has a short (sensor or cable failure.) 

 
 
 
 
 

 

The DataCOLD 500 R/T recorders have an option to adjust the offset of the A/D converter with a 
correction factor. Because this offset is subject to aging it is recommended to repeat this 
procedure on a regular basis (i.e. at the annual reference check). 
 
The correction factor is a fixed parameter used in the formula which converts the measured 
resistance into the corresponding temperature. This procedure is not applicable for calibrating 
individual sensors. Note that the effect on the measured and displayed Temperature is not linear.

Set the correction factor 

•  Connect to Temperature input 1 a precision resistor 

of 1500 Ω (0,1%).

•  Enter the parameter menu by pressing the green 

button for 2 seconds. The display will show: "ENTER 
PINCODE". The factory setting of the pin code is  
1111.  

•  After entering the correct pin code you have access 

to the parameter menu’s. Select menu 10.6 and 
press [edit].   

10.5 Corr.factor  
Recommended: +2 
Setting: +1 

   

ACCEPT   <-CNCL 

•  The recorder will now compare the measured value 

of the resistor with the ‘expected’ value of 1500 Ω. 

•  The second line the recorder will display a 

recommended correction factor based on the 
measured value. This factor can be set on line three. 

•  After pressing ‘accept’ this correction factor will be applicable for all Temperature inputs. The 

correction factor is limited from -9 to +9.
