Model DMM6500 Quick Start Guide
Safety precautions The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous conditions may be present. This product is intended for use by personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured. For safety, instruments and accessories must be used in accordance with the operating instructions.
Power and envrionmental specifications For indoor use only.
Introduction Contact information Thank you for choosing a Keithley Instruments product. The DMM6500 is a 6½ digit bench/system digital multimeter with scanning that expands standard DMM functions with high-speed digitizing and large graphical color touchscreen display. This DMM offers a broad range of measurement capabilities, including 15 measurement functions.
Unpack and inspect the instrument To unpack and inspect the instrument: 1. Inspect the box for damage. 2. Open the box. 3. Remove the bag that contains the documentation, standard accessories. 4. Remove the DMM6500 from the box. 5. Remove the packaging insert. 6. Inspect the instrument for any obvious signs of You should have received the DMM6500 with: 1. 2. 3. 4. 5.
Check fuse settings The fuse is set at the factory. Check the power module on the back of the instrument. The correct voltage setting should be displayed. To change the fuse orientation: 1. 2. 3. 4. Make sure the POWER is off. Remove all test leads connected to the instrument. Remove the power cord. Squeeze the tabs on the fuse case and remove the fuse case from the power module. 5. Remove the fuse from the fuse case. 6.
Connect the instrument • Important test system safety information This product is sold as a stand-alone instrument that may become part of a system that could contain hazardous voltages and energy sources. It is the responsibility of the test system designer, integrator, installer, maintenance personnel, and service personnel to make sure the system is safe during use and is operating properly.
• • • Where possible, use automatic handlers so operators are not required to access the DUT or other potentially hazardous areas. Provide training to all users of the system so they understand all potential hazards and know how to protect themselves from injury. During power up in many systems, the outputs may be in an unknown state until they are properly initialized. Make sure the design can tolerate this situation without causing operator injury or hardware damage.
Install the instrument You can use the DMM6500 on a bench or in a rack. If you are installing the DMM6500 in a rack, please see the instructions that came with your rack-mount kit. To prevent damaging heat build-up and ensure specified performance, make sure there is adequate ventilation and air flow around the instrument to ensure proper cooling. Do not cover the ventilation holes on the top, sides, or bottom of the instrument.
To connect the power cord: 1. Connect the supplied power cord to the AC receptacle on the rear panel. 2. Connect the power cord to a grounded AC outlet. To turn a DMM6500 on: 1. Disconnect any devices under test (DUTs) from the DMM6500. 2. Press and hold the POWER switch for two seconds. The indicator next to the POWER switch shows amber in the off state and green in the on state when connected to the power source. The instrument displays a status bar as the instrument powers on.

Connections for testing 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 DUTs from the instrument before powering the instrument. Safe installation requires proper shields, barriers, and grounding to prevent contact with test leads.
For this example, you can make the connections with the Model 1757 Standard Test Lead Kit. To make connections: 1. Make sure the front panel POWER switch is off. 2. Connect the red lead to the INPUT HI connection. 3. Connect the black lead to the INPUT LO connection. Verify measurement operation The following steps provide a quick way to verify that the instrument is operating correctly. The voltage measurements appear in the DC VOLTAGE area of the home screen and should read approximately 0 V.
FAQs Is there any software to help me get started? Where can I find updated drivers? Yes. KickStart and TestScript Builder can help you get started with the DMM6500. For the latest drivers and additional support information, see the Keithley Instruments support website. KickStart is a software program that allows you to set up the instrument and run a test without using any programming languages.
How do I upgrade firmware? Upgrade files are available at tek.com/keithley. Do not turn off power or remove the USB flash drive until the upgrade process is complete. From the front panel: 1. Copy the firmware file (.upg file) to a USB flash drive. 2. Verify that the firmware file is in the root subdirectory of 3. 4. 5. 6. 7. 8. the flash drive and that it is the only firmware file in that location. Disconnect any terminals that are attached to the instrument. Turn the instrument power off.
How do I change the command set? You can change the command set that you use with the DMM6500. The 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.
Why can’t the DMM6500 read my USB flash drive? How do I save the present state of the instrument? Verify that the flash drive is formatted with the FAT file system. The DMM6500 only supports FAT drives. 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. In Microsoft® Windows®, you can check the file system by checking the properties of the USB flash drive.
Why did my settings change? Many of the commands in the DMM6500 are saved with the measure function that was active when you set them. For example, assume you have the measure function set to current and you set a value for display digits. When you change the measure function to voltage, the display digits value changes to the value that was last set for the voltage measure function. When you return to the current measure function, the display digits value returns to the value you set previously.
