Data Acquisition / Multimeter System User's Manual Section 8: Mixed function multi-
DAQ6510-900-01Rev. A / April 2018 8-3
There is no internal connection between protective earth (safety ground) and the LO
terminals of the DAQ6510. Therefore, hazardous voltages (more than 30 V
RMS
) can appear on
LO terminals. This can occur when the instrument is operating in any mode. To prevent
hazardous voltage from appearing on the LO terminals, connect the LO terminal to protective
earth (safety ground) if your application allows it. You can connect the LO terminal to the
chassis ground terminal on the front panel or the chassis ground screw terminal on the rear
panel. Note that the front-panel terminals are isolated from the rear-panel terminals.
Therefore, if you are using the front-panel terminals, ground to the front-panel LO terminal. If
using the rear-panel terminals, ground to the rear panel LO terminal. Failure to follow these
guidelines can result in injury, death, or instrument damage.
Mixed function multi-channel scanning
This application example uses the DAQ6510 to execute complex multi-channel, mixed function
scanning in a production-test environment.
For this application, you will:
• Configure the instrument for:
One channel each of ACV, ACI, and DCI.
Nine channels of DCV.
Four channels of temperature using Type K thermocouples using a simulated reference junction.
• Set labels on certain channels to help better identify what the measurement is monitoring at the
DUT.
• Step through the scan to check each individual channel reading prior to scanning.
• Execute 10 scans for each selected channels.
• Use the reading table to view (or print) the scanned measurements.
You can operate the instrument through the front panel or using SCPI or TSP code. For information
about setting up remote communications, see Remote communications interfaces (on page 3-1
).
