XS series operating manual
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%
