Calibrating the Analog Output Subsystem

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

Choosing a Calibration Meter

To calibrate the analog output circuitry, you can use either of the following meters:
• The internal A/D converter (ADC) on the DT3010 Series board.
Using the board's ADC as an input to the analog output circuitry allows you to calibrate
the analog output circuitry quickly without using external equipment.
• An external precision meter.
The following sections describe how to configure for calibration using either of the supported
meters. If you are using STP268, it must be attached to connector J1 in all the steps below.

Configuring for the Internal ADC

To calibrate DAC0 using the internal ADC, do the following:
1. Connect Analog Out 0+ (TB41) to Analog In 2 (TB5).

Analog Output 0+
Analog Input 2
2. Connect Analog Out Return to Analog In 2 Return.
