Channel:Channel: A channel is a physical IO point that can be either analog or digital.
User Zero Correction: Manually adjust the user offset calibration for analog inputs/outputs. Every analog/input is cali‐
brated at the factory according to the 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.
Zero or Offset calibrations are used to adjust the reported value from 5 to 15% full scale. The calibration can be
adjusted coarsely by moving the slide bar from left to right with a mouse. For fine adjustments, use the ‐/+ buttons on
either side of the slide bar. The corresponding adjustment will be displayed in the calibration configuration. The cali‐
bration 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 adjust‐
ment (positive calibration 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 calibrations:
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 the 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 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.
