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.
