12.CALIBRATION PROCEDURE

Calibration requires a voltmeter (at least 5 digits of precision is preferred) and a miniature screwdriver to turn the potentiometer screws. The common lead of the voltmeter must be connected to analog ground (not digital ground). The best source for this connection is any of the analog ground pins on the user I/O header J3.

⇒Note: All steps should be completed in the sequence shown, since each step affects the following steps. (Steps 4 and 5 may be interchanged since they do not depend on each other.)

+5.000V Reference Voltage Adjust

Install a jumper in position “5” on J4. Connect the high side lead of the voltmeter to the upper pin of J4 under either location marked “F”. Adjust R1 so that the voltmeter reads +5.000V.

+10.00V Reference Voltage Adjust

Keep the voltmeter connected to as described above. Remove the jumper in position “5” on J4 and adjust R2 so that the voltmeter reads +10.000V.

Adjustable Reference Adjust

This step can be skipped if you are not using the adjustable reference.

Connect the voltmeter to the upper pin of J4 below either location marked “A” on J4. Adjust R3 so that the voltmeter reads the desired full-scale voltage range. This voltage is factory-preset to 2.500V. Any adjustment from about 1V to slightly over 2.5V is achievable.

Negative Full-Scale Reference Adjust, Channels 0 - 7

Install jumpers in positions “5” and the leftmost “F” on J4. Connect the voltmeter to the upper pin on J4 under the leftmost “B”. Adjust R4 so that the voltmeter reads –4.999V. With this setting, the D/A will actually output closer to –5.000V when it is loaded with all zeros. This value can be adjusted later if desired by measuring the actual D/A output.

Negative Full-Scale Reference Adjust, Channels 8-15

Install jumpers in positions “5” and the rightmost “F” on J4. Connect the voltmeter to the upper pin on J4 under the rightmost “B”. Adjust R5 so that the voltmeter reads –4.999V.
