Calibrating the Analog Input Subsystem 

This section describes how to configure the DT740, STP268, or STP268-EC screw terminal 
panel for an internal or external reference, and how to use the DT3010 and DT3016 calibration 
utilities to calibrate the analog input subsystem of the board.

Choosing a Calibration Reference 

To calibrate the analog input circuitry, you can use either of the following references:

• The in5 V reference on the DT3010 Series board.

Using the +5 V reference on the board allows you to calibrate the analog input circuitry 
quickly without using external equipment; the accuracy of the calibration is 
approximately 0.05%.

• An ex9.3750 V reference (precision voltage source).

Using an ex9.3750 V reference provides an accuracy of approximately ±1 LSB.

This section describes how to configure for an internal or external reference. If you are using 
STP268, it must be attached to connector J1 in all the steps below. 

Configuring for the Internal Reference 

To calibrate the analog input circuitry using the in5 V reference, do the following: 

1.

Connect Analog In 0 to +5 V Reference Out. 

2.

Connect Analog In 0 Return to Analog Ground.
