You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum cable length is the lesser of either: • The number of devices multiplied by 2 m (6.5 ft) • 20 m (65.6 ft) You may see erratic bus operation if you ignore these limits.
Model DMM6500 6½ Digit Multimeter User's Manual Section 3: Using a remote interface Installation Slot covers must be installed on unused slots to prevent personal contact with high-voltage circuits. Failure to recognize and observe standard safety precautions could result in personal injury or death due to electric shock. To install the communications card: 1. Turn the instrument off and disconnect the power line cord and any other cables connected to the rear panel. 2.
Section 3: Using a remote interface Model DMM6500 6½ Digit Multimeter User's Manual To allow many parallel connections to one instrument, stack the connectors. Each connector has two screws on it to ensure that connections remain secure. The figure below shows a typical connection diagram for a test system with multiple instruments. To avoid possible mechanical damage, stack no more than three connectors on any one instrument.
Model DMM6500 6½ Digit Multimeter User's Manual Section 3: Using a remote interface Set the GPIB address The default GPIB address is 16. You can set the address from 1 to 30 if it is unique in the system. This address cannot conflict with an address that is assigned to another instrument or to the GPIB controller. GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an address of 21. The instrument saves the address in nonvolatile memory.

Section 9: Measuring power using digitizing and TSP-Link Model DMM6500 6½ Digit Multimeter User's Manual Equipment required This application requires the following equipment: • Two DMM6500 instruments • Two KTTI-TSP communication and digital I/O accessory cards • One computer set up for communication with the instrument • One ethernet crossover cable • Several insulated banana cables • One device or component to be tested Device connections This application requires two KTTI-TSP communication
Model DMM6500 6½ Digit Multimeter User's Manual Section 9: Measuring power using digitizing and TSP-Link Figure 44: Two nodes measuring current and voltage To prevent electric shock, test connections must be configured such that the user cannot come in contact with test leads or any device under test (DUT) that is in contact with the conductors. It is good practice to disconnect power before connecting DUTs.
Section 9: Measuring power using digitizing and TSP-Link Model DMM6500 6½ Digit Multimeter User's Manual Measuring power using digitizing and TSP-Link For this application, you will: • Set the TSP-Link nodes for the DMM6500 instruments to 1 and 2. • Reset the instruments. • Initialize TSP-Link. • Configure the input and output TSP-Link triggers for the DMM6500 instruments. • Set up the digitize function. • Set up trigger models on both instruments.
Model DMM6500 6½ Digit Multimeter User's Manual Section 9: Measuring power using digitizing and TSP-Link The communication from the computer is made directly to the first DMM6500 (node 1) in the following TSP code. This code makes the first DMM6500 the master in this TSP-Link network, with the second DMM6500 as the subordinate. You can change the master to be the second DMM6500, but you must modify the code and modify how the TSP-Link network is initialized. The master node does not require the node[x].

Section 10: Troubleshooting FAQs Model DMM6500 6½ Digit Multimeter User's Manual As delivered from Keithley Instruments, the DMM6500 is set to work with the SCPI command set. If you choose the SCPI2000 or SCPI34401 command set, you will not have access to some of the extended ranges and other features that are now available using the default SCPI command set. In addition, some Series 2000 or Keysight 34401 code will work differently in the DMM6500 than it did in the earlier instrument.
Model DMM6500 6½ Digit Multimeter User's Manual Section 10: Troubleshooting FAQs How do I save the present state of the instrument? You can save the settings in the instrument as a script using the front-panel menus or from a remote interface. After they are saved, you can recall the script or copy it to a USB flash drive. From the front panel: 1. Configure the DMM6500 to the settings that you want to save. 2. Press the MENU key. 3. Under Scripts, select Save Setup. 4. Select Create.
Section 10: Troubleshooting FAQs Model DMM6500 6½ Digit Multimeter User's Manual How do I save what is displayed on the screen? You can save a screen capture of the front-panel display to a graphic file on a USB flash drive. The instrument saves the graphic file in PNG file format. To save a screen capture: 1. Insert a USB flash drive into the USB port on the front panel of the instrument. 2. Navigate to the screen you want to capture. 3. Press the HOME and ENTER keys.
