The programming steps——Agilent Commands:
0 cmdset□agilent /*Select Agilent commands*/
1 *CLS /*Clear the instrument state*/
2 *IDN? /*Query equipment ID to confirm if the instrument
works normally*/
3 /*Return: RIGOL Technoligies, DM3058, DM3A020080808, 99.00.00.00.00.00*/
4 conf:res□min /*Set resistance measure function*/
5 /*Short-circuit the red and black test lead which are used for resistance
measurement*/
6 calc:stat□on /*Enable math operation function*/
7 calc:func□aver /*Enable average calculation function*/
8 calc:aver:aver? /*Query the average resistance*/
9 /*Return: 3.079573e-03*/
10 calc:func□null /*Enable NULL operation function*/
11 calc:null:offs? /*Query the current NULL offset*/
12 /*Return: 0.000000e+00 */
13 calc:null:offs 0.000379573 /*Set the measured offset as the NULL offset*/
14 calc:func□null /*Use the new offset to perform NULL operation*/
15 calc:func□aver /*Enable average calculation function*/
16 calc:aver:aver? /*Query the average resistance*/
17 /*The new measured value: 3.313395e-07 */
Remarks:
1. Execute the operations described in line 5 before sending command line 6.
2. The result shown in line 16 indicates that after the relative operation, the
measured resistance value reduced 4 magnitudes (from -03 to -07).
