Calibration Program D-3
General program instructions
Follow the steps below to use the example calibration program, which calibrates both Chan-
nel #1 and Channel #2.
1. With the power off, connect the Model 2306 and the digital multimeter to the IEEE-488
interf
ace of the computer. Be sure to use shielded IEEE-488 cables for bus connections.
2. Turn on the computer, the Model 2306, and the digital multimeter. Allow the Model
2306
and the multimeter to warm up for at least one hour before performing calibration.
3. Make sure the Model 2306 is set for a primary address of 16.
4. Make sure the digital multimeter prim
ary address is set to 17.
5. Make sure that the computer bus driver so
ftware (CECHP.EXE) is properly initialized.
6. Enter the QBasic editor, and type in Program C-1
. Be sure to use the actual characterized
resistor values when entering the parameters.
7. Check thoroughly for errors, then save the program using a convenient filename.
8. Run the program, and follow the prompts on the screen to perform calibration. For test
conne
ctions, refer to the following figures in Section 14:
• Voltage connections: Figure 14-1.
• 5A current connections: Figure 14-2.
• 5mA current connections: Figure 14-3.
