Probe compensation continued… 

 
When prompted,  attach  a  small  length  of 
tinned  copper  wire  between  the  two  test 
probes.  Now  let  the  leads  rest  on  a  non-
conductive surface, try not to touch them 
during the compensation procedure. 
 
When  you’re  happy  that  a  suitable  good  link  is  present 
between the probes, briefly press the 

enter-off

 button.  

 
 
After a short time, the instrument will ask 
you to remove the link from the probes. 
 
 
 
At  that  point,  remove  the  link,  rest  the  probes  on  a  non-
conducting  surface  and  don’t  touch  them.  When  you’ve 
done that you can briefly press 

enter-off

 
 
If  the  LCR45  is  happy  with  the  measurements  that  it  has  taken  during  the 
probe compensation procedure, you will see the following message: 
 

Probe properties
stored.

 

 

 

 

Please  note  that  probe  compensation  is  particularly  important  when 

analysing low value inductors, capacitors and resistors. 

Short the probes
then press enter

Open the probes
then press enter
