7.3.4 CALIBRATION OF RESISTANCE  MEASUREMENT INPUT 

UR.

 

To open window 

Calibration SA10A

 see 

7.3 Recalibration procedure.

 

 

 

Click tab Resistance in window Calibration SA10A. 

 

Click on button 

Calibration wizard

.  

 

The following window is displayed. 

 

•

 

Calibration wizard. Step 1. 
 

Calibration of voltage input 

Ur

. 

 
Important! 

Calibration of input 

Ur

 must be done 

before

 the calibration 

of the current measuring Ir. 
 
This input is used as a reference instrument when the 
current 

Ir

 is calibrated. 

 

 

•

 

Calibration wizard. Step 2. 
 

Connect a stable DC-voltage source  
(-0.2000 - +0.2000V) parallel with and a voltage instrument 
to the selected input. 
For more information about connection see. 

7.2.4 Check resistance measuring inputs Ur, Ir.
