RIGOL DMMs require a Null Modem Cable connection.

Each line should terminate in a carriage return followed by a line feed (“/r/n”)

These settings should enable you to connect to the DMM in Serial mode.

Here are the steps for determining the serial number and firmware revision of your DM3000 series of DMM. 1. Press the Utility button
2. Press the T/C softkey
3. Press the Info softkey

NOTE: You can use the Range Up and Down arrows to move through the various items in the display

Follow the steps below:
1. Press ‘Utility’
2. Select ‘T/C’
3. Hold the fifth key for 3s to show the ex version
4. Hold the same key for 3s to hide the ex version

The DM3068 is capable of a reading rate of 2000 readings/sec when controlled via USB, Ethernet, or serial bus. 

This article provides the sequence of commands to enable DCV measurements at the fastest rate.

The LabVIEW 2010 VI allows remote programming of the instrument for fast data collection. You can download the software file here.

We created DM3068FastData.VI to allow users  to remotely program Rigol DM3068 Digital Multimeters. It is built using LabVIEW 2010 and utilizes National Instruments VISA for communication over USB.
The program allows users to select DC Volts or DC Current and acquire data as quickly as possible (2K readings/sec). 
Steps:
1. Connect power cord to instrument
2. Connect USB cord to instrument and PC. The PC should recognize the DMM and notify you that a new Test and Measurement Device (IVI) has been connected.
3. Connect the DMM to the circuit or device of interest. 

4. Select the instrument of interest from the VISA Resource Name Drop down 


5. Select the Measurement Function of interest



6. Select the NPLC’s (Measurement integration rate) and number of measurements 



7. If you would like to save the data, check the “Save Data?” checkbox. This will allow you to select the location of the saved Text File.


8. Once the instrument is configured for the measurements, just press the LabVIEW Run arrow to run the program.


9. Then press “RUN” to execute the commands. 



10. As the instrument collects data, it will place the new readings in the Data indicator.


11.After the instrument has performed all of the measurements selected, the program will finish. If you have selected the “Save Data?” option, select the location and enter a file name with either TXT or CSV as the extension to save. NOTE: If you cancel the data save, a LabVIEW error will appear.. press continue.


File Format: The saved file is formatted with the date, time, and function header followed by comma separated readings.

We created DM3068Basic.VI to allow users  to remotely program Rigol DM3068 Digital Multimeters. It is built using LabVIEW 2010 and utilizes National Instruments VISA for communication over USB.
The program allows users to select from a number of basic instrument functions, like DC Volts, AC Current, and resistance. It also allows the user to define a number of readings to return as well as a delay, or dwell, between measurements.
In this way, a user could collect data over a specific time frame with data points collected on a defined interval.
Steps:

1. Connect power cord to instrument
2. Connect USB cord to instrument and PC. The PC should recognize the DMM and notify you that a new Test and Measurement Device (IVI) has been connected.
3. Connect the DMM to the circuit or device of interest.
4. Select the instrument of interest from the VISA Resource Name Drop down 
5. Select the Measurement Function of interest   
6. Select the number of measurements and measurement delay

Data Trend will not initialize with the default folder selected:

C:\Program Files (x86)\RIGOL\Ultra Sigma\

Changing the folder will fix this issue. For example changing the folder to “D:\Rigol” will allow Data Trend to initialize.

1.    Insert USB stick (FAT32 format) 
 
2.    Change the trigger source to single. This mode allows you manual control of the start of the data acquisition as well as allowing you to control the number of samples acquired.  
 
Press TRIG > SOURCE > SINGLE  
  
 
3.    Press DONE and the SINGLE button will become enabled 
 
4.    Press SET > SNO to set the number of samples.   
 
NOTE: Use the right and left arrows to move the cursor to the decimal place you wish to change and then use the up and down arrows to increment or decrement the value. In this example, we set the number of samples to 1000. 
 
 
5.    Press DONE to accept the changes. 
 
6.    Press TRIG to back out of the trigger menu and get back to the measurement display.  
 
NOTE: The display is no longer updating. The rotating indicator and digits are fixed. The meter is now waiting for manual input before it will begin updating.  

  
7.    Clear the memory data by changing functions. In this example, we switch from DCV to ACV and back to DCV.  
 
NOTE: The record number (in HISTORY) is set to 0 after the function change.   
 
 
8.    Select the function that you wish to use during the data acquisition process. 
 
9.    Press SINGLE to begin the data acquisition 
 
10.    The instrument display will continue to update until the data buffer is filled with the number of samples that were set earlier.  
  
      
11.    You can take a look at the statistics as well as the number of samples collected   by pressing HISTORY 
 
12.    To Save the data, press SAVE > Set Disk to A:\ > Set TYPE to Meas_CSV 
 
  
13.    Press SAVE to open the text entry field, name the file, and press DONE to  write the CSV data to the external USB drive.

These steps will allow you to use your Rigol DM3068 to take temperature measurements with and RTD (Resistance Temperature Detector). You will need to know the R0 of your RTD, which is the resistance at 0 degrees Celsius, and the Alpha value, which is the rate at which the resistance scales over temperature. 

Note: The process for using a DM3058 is similar, but the menu items may have different names.

1. Select Sensor > Temp > New > RTD > R0
2. Input the R0 resistance for your temp probe 
3. Press Alpha and choose the correct alpha value for your temp probe
4. Press (back) > 2WR of 4WR depending on how many inputs your probe is using (2 or 4 wires)
5. Press (back) > (back) > Unit and choose desired temp unit
6. Press (back) > Done > Save
7. Name the save state if you want 
8. Press (back) > Done > Apply 
NOTE: This last step is a little unintuitive, but very important. If you don’t back up after saving and press apply, nothing will happen. 

Once You have create this sensor mode, the next time you want to switch into it you will just need to press Sensor > Load, then after making sure your desired setting file is highlighted, press Read.
