Why can't the DAQ6510 read my USB flash drive?

Verify that the flash drive is formatted with the FAT32 file system. The DAQ6510 only supports FAT

and FAT32 drives using MBR (Master Boot Record).
In Microsoft

Windows

, you can check the file system by checking the properties of the USB flash

drive.

How do I change the command set?

You can change the command set that you use with the DAQ6510. The remote command sets that

are available include:

•

SCPI: An instrument-specific language built on the SCPI standard.

•

TSP: A scripting programming language that contains instrument-specific control commands that

can be executed from a stand-alone instrument. You can use TSP to send individual commands

or use it to combine commands into scripts.

•

SCPI2700: An instrument-specific language that allows you to run code developed for Keithley

Instruments Series 2700 instruments.

•

SCPI2701: An instrument-specific language that allows you to run code developed for Keithley

Instruments Series 2700 instruments.

You cannot combine the command sets.

As delivered from Keithley Instruments, the DAQ6510 is set to work with the DAQ6510 SCPI

command set.

To set the command set from the front panel:

1. Press the

MENU

key.

2. Under System, select

Settings

3. Select

Command Set.

You are prompted to reboot.
