3. Set your analog device for a near full scale (85 to 95% full scale) output. Compare the value currently being reported with

the value on your meter. If they are not equal, adjust the span value by using the slide bar and arrows in the span display

box. Click the Apply button and observe the effect of the new span factor. Repeat this step unit a satisfactory reading is

obtained.

4. The channel is now calibrated.

User Span Correction: Manually adjust the user span calibration for analog inputs/outputs. Every analog input/output

is calibrated at the factory according to specified accuracy. The user calibration is supplied to account to adjust the

reported values to account for wiring or instrumentation errors. For this reason, most inputs/outputs will NOT need to

be calibrated. Span calibration are used to adjust the reported value from 85 to 95% of full-scale.

The calibration can be adjusted coarsely by moving the slide bar to the left or right with a mouse. For fine adjust-

ments, use the -/+ buttons on either side of the slide bar. The corresponding adjustment will be displayed in the cali-

bration configuration. The calibration will not take effect until the apply button is clicked. A negative adjustment

(negative calibration value) will cause the reported channel value to go down. A positive adjustment (positive calibra-

tion value) will cause the reported channel value to go up. The larger the calibration value, the greater the difference

will be between the reported channel value and the actual measured value.

Instructions on adding user calibration:

Use this method to calibrate a channel using the manual slide bar user calibration:

1. Set your analog signal device for a near minimum (5 to 15% full scale) output. Measure the device’s output at the mod-

ule’s screw terminals with a precision meter or external standard monitor.

2. Apply the small signal to the analog input channel. Compare the value currently being reported with the value on your

meter. If they are not equal, adjust the Offset value by using the slide bar and arrows in the Offset display box. Click the

Apply button and observe the effect of the new offset factor. Repeat this step until a satisfactory reading is obtained.

3. Set your analog signal device for a near full scale (85 to 95% full scale) output. Compare the value currently being

reported with the value on your meter. If they are not equal, adjust the Span value by using the slide bar and arrows in the

Span display box. Click the Apply button and observe the effect of the new span factor. Repeat this step until a satisfactory

reading is displayed.

4. The channel is now calibrated.

Health Monitor

• Click on the Health Monitor button and the dialog window below will appear. This dialog window will supply the

user with feedback on the unit’s temperature and power readings.
