 Calibration 

7.2  VR Assignment 

There are eight variable resistors (VR) on the PCI-9812/10 board to 
allow you to make accurate adjustments on A/D channels. The 
function of each VR is specified in Table 7.1. 

 

VR1 

A/D channel 0 offset adjustment 

VR2 

A/D channel 1 offset adjustment 

VR3 

A/D channel 2 offset adjustment 

VR4 

A/D channel 3 offset adjustment 

VR5 

A/D channel 0 full scale adjustment 

VR6 

A/D channel 1 full scale adjustment 

VR7 

A/D channel 2 full scale adjustment 

VR8 

A/D channel 3 full scale adjustment 

Table 7.1 Function of VRs 

 

7.3  A/D Calibration 

7.3.1 

AD Calibration for Channel 0 

1.  Apply a +1V input signal to A/D channel 0, and trim the 

VR5

 to 

obtain the range of the average reading of channel 0 is within 
2046.6

±

0.1 (9812) or 510.9

±

0.1  (9810). 

2.  Apply a +0V input signal to A/D channel 0, and trim the 

VR1

 to 

obtain the range of the average reading of channel 0 is within 

±

0.2. 

3.  Repeat step 1 and step 2, adjust 

VR5

 and 

VR1

. 

7.3.2 

AD Calibration for Channel 1,2,3  

You could calibrate other channels with the same procedure in 
section 7.3.1 while trimming the corresponding VRs.  Refer the 
following table to adjust the correct VR.
