XS user manual v0.55  - 106 - 
Megohmmeter mode, 2 outputs setup 
 
Refer to section related to the board jumpers setup. This setup is the factory default setup. 
The pin 2 of the rear panel connector C6 gives the value of the resistance in a range (V1). 
The pin 1 of the rear connector C6 gives the value of the range (V2). 
 
V1= value in a range, from 0 to 10 volts compared to the displayed value 
 
V2= value of the range : 
   
 
 
The resistor value is given by the following formula : 
 
       
 
For example : if V1=5.2 V and V2=3.0 V then R=10.4 Mohms 
 
 
Accuracy of the 0-10 volts output voltage compared to the display : 
 
      ±(0.1% + 5 mV) 
 
 
Megohmmeter mode, 1 output setup 
 
Refer to section related to the board jumpers setup.  
The pin 1 of the rear panel connector isn't used 
The pin 2 of the rear connector gives the logarithmic value of the measured resistor (V1) 
 
The resistor value is given by the following formula : 
 
 
 
For example: if V1=3.7V then R=10.0 Mohms 
 
Accuracy of the 0-10 volts output voltage compared to the display : ±(0.1% + 5 mV) 
 
Accuracy of the resistance computed with the output voltage :    ±1%
