RIGOL
Programming Guide for DM3058/DM3058E 6-2
Example 1: Reading Statistic
Purpose: To implement the maximum statistic through commands.
When the maximum statistic is enabled, the first reading is regarded as the maximum
shown, and then, this value is updating continuously along with readings measured
until the maximum value is captured, please perform with following procedures step
by step:
The programming implementations—— RIGOL Commands
0 *RST
/* Reset the instrument*/
1 cmdset rigol /* Select RIGOL commands */
2 *IDN? /* Query the equipment ID and confirm if the multimeter works
normally */
3
/*Return Format:RIGOL Technologies, DM3058, DM3A020080808,
99.00.00.00.00.00*/
4 :function:voltage:DC
/* Enable the DC voltage measurement */
5 :measure AUTO /* Select Auto measurement */
6 :calculate:function max /* Enable the maximum statistic */
7 :calculate:statistic:max? /* Query the current maximum of DC voltage */
8 /*Return Format:5.000064e-02*/
9 :calculate:statistic:count? /* Query the current times of Auto measurement*/
10 /*Return Format:252*/
11 :calculate:function none /* Exit the math function */
Explanations:
1. The returned value in line 7 is the current maximum DC voltage.
2. The returned value in line 9 is the measured times that have been completed.
