1. Channel Setting
Similar to analog input configuration, you can set different range for each
analog output channel. Select the channel number in the Channel index
combo box, and then select the range in the Output range combo box.
After selecting appropriate range, click the Apply button.
At the bottom left-hand corner of the Output tab, you can define the ana-
log output value by using the horizontal pointer slide or the Value to Out-
put text box. After you have chosen the appropriate analog output value,
click the Apply output button.
Besides, you can set the startup value of the specific analog output chan-
nel. (The analog output channel will generate the startup value output
when it is power-on. In other words, start-up value can be considered as a
power-on value.) Use the horizontal slider or the Value to output text
box to define the value and click Apply button. Then click the Set as
startup button to save that value as startup value.
At the bottom right-hand corner of the Output tab, it is Calibration area.
There are two buttons used to calibrate the maximum and minimum value
of full range. The label on the buttons will change depending on the out-
put range. Take figure 5.11 as example, labels on the two buttons are
Trim for 4 mA (calibrate for minimum value of full range) and Trim for
20 mA (calibrate for maximum value of full range).
After you click one of the buttons, one dialog window will appear. Use
another instrument to measure the output value. Then use the four buttons
(-10, -1, +1, +10) on the dialog window to correct the analog output
value. For example, if you click the Trim for 4 mA button, the specific
analog output channel should generate 4 mA. However, the instrument
reads 3.88 mA. So you need to use +1 and +10 button to adjust the output
value, until the output value is truly 4 mA.
In the top right-hand corner of the Output tab, you can control the digital
output value by the DO 0 and DO 1 button. Their value will be display by
the LED near the button.
