DMM6500 6½-Digit Bench/System Digital Multimeter
DATASHEET
The DMM6500 is a modern bench/system DMM delivering
more measurement functionality, best-in-class
measurement insight, and a price that will not break your
budget. The most recognizable feature of the DMM
is the large 5-inch (12.7 cm) capacitive touch screen
display that makes it easy to observe, interact with, and
explore measurements with “pinch and zoom” simplicity.
Beyond its display technology, the DMM 6500 superior
analog measurement performance delivers 25 PPM basic
DCV accuracy for one year and 30 PPM for two years,
potentially allowing you to extend your calibration cycles.
The DMM6500 is equipped with all the measurement
functions you would expect in a bench multimeter,
so there’s no need to buy additional measurement
capabilities. Its 15 measurement functions, including
capacitance, temperature (RTD, thermistor, and
thermocouple), diode test with variable current sources,
and up to 1 MS/sec digitizing are now included.
The digitizing function can be used for voltage or current
and is especially useful in capturing transient anomalies
or to help profile power events such as the operating
states of today’s battery operated devices. Current and
voltage can be digitized with a programmable 1 MS/sec
16-bit digitizer, making it possible to acquire waveforms
without the need for a separate instrument.

Capture and Analyze Voltage or Current Transitions
Power analysis is becoming more important in today’s electronic designs. Designers must now consider more efficient
components and complex system design typically requiring multiple power states. The DMM6500 has the tools you
need to help design and troubleshoot these complex systems. Eight different current ranges allow measurements from
10 amps down to 10 pico-amps, giving you the dynamic range to measure your power states. In addition, a built-in 1 MS/sec
digitizing function can help capture transient events, allowing you to see and analyze transitions as they occur.

Multi-channel/Scanning Applications
When characterizing or profiling your design it is often critical
to make a series of measurements. In these applications
the need for automated multi-channel measurements is
advantageous. The DMM6500 is equipped with a scanner
card slot allowing up to 10 channels of switching, giving
you the capability to make automated multi-channel
measurements. Plugging in the 2000-SCAN card gives users
up to 10 channels of 2-pole measurements or 5 channels of
4-pole measurements. Functions can be programmed on a
per-channel basis if supported by the switch topology.
Temperature Measurement
Applications
Temperature is one of the most measured signal types in
the world, and the DMM6500 has many options to help you
make this measurement. Besides RTD, thermistor, and
thermocouple functions, you can equip your DMM with a
nine-channel scanner card with built-in CJC for automated
thermocouple temperature scanning. This feature is
very useful when your design requires thermal profiling,
especially when enclosed in a temperature chamber.

Application Programs
The DMM6500 is factory installed with application
programs to help you get more out of your instrument.
These application programs appear when the instrument
is used in the TSP or native SCPI communication
language mode. These examples highlight the unique
ability of the DMM6500 to run specialized applications
which customize the user interface. This can significantly
change the way information is displayed or even
automated in performing an application
Menu of application programs that can customize the display or perform special functions.

System Integration and Programming
Users have maximum programming flexibility with the DMM6500. In addition to traditional SCPI programming (default), the unit
can also be configured for SCPI emulation for the Keithley 2000 or the Keysight 34401A. Additionally, Keithley’s powerful Test
Script Processor (TSP®) programming is another option that allows unique single- or multi-instrument testing applications
where speed is critical.

TSP®^ Script Conditional branching Calculations and flow control Pass/Fail test Prober/Handler control Datalogging/ Formatting
TSP-Link ®
TSP®^ scripting allows running powerful test scripts directly on the instrument, without the need for an external PC controller.
These test scripts are complete test programs based on an easy-to-use yet highly efficient and compact scripting language,
LUA (www.lua.org). Scripts are a collection of instrument control commands and/or program statements. Program
statements control script execution and provide facilities such as variables, functions, branching, and loop control. This
allows you to create powerful measurement applications without an integrated development environment (IDE). Test scripts
can contain any sequence of routines that are executable by conventional programming languages (including decision-making
algorithms), so the instrument can manage every facet of the test without the need to communicate with a PC for decision
making. This eliminates delays due to GPIB, Ethernet, or USB traffic congestion and greatly improves test times.
TSP technology also offers mainframe-less channel
expansion. The KTTI-TSP is a user installable accessory
card offering connectivity to TSP-Link®^ technology.
This channel expansion bus allows connecting multiple
DMM6500’s or other TSP-enabled instruments together
to form a tightly synchronized instrument system.
Connection is provided with simple low cost Category 5
Ethernet crossover cabling. The system is organized in a
master-subordinate configuration, essentially allowing the
connected instruments to act as one. Other Keithley TSP-
enabled instruments include the 2450 and 2460 Graphical
SourceMeter®^ SMU Instruments, Series 2600B SourceMeter®
SMU Instruments, DMM7510, DAQ6510, and the Series
3700A Switch/Multimeter Measurement systems. TSP-Link
technology supports up to 32 units, so it’s easy to scale a
system to fit the requirements of an application.

DC Voltage Ratio
DC Voltage Ratio Calculation 35
Method Measurement
Channel Ratio (through rear input scanner card)
Channel A Channel Ratio = ___________ Channel B Accuracy = (Accuracy of channel A measure range + Accuracy of channel B measure range) × Channel ratio
Channel Average (through rear input scanner card)
Channel A + Channel B Channel Average = _______________________ 2 Accuracy = Accuracy of channel A measure range + Accuracy of paired channel B measure range
DCV Input Ratio (HI-LO/SHI–SLO) 36
HI signal Ratio = _______________________ SHI signal – SLO signal HI range 10 V Accuracy = ( _________^ × DCV% of range accuracy + _______________________^ × 0.0008% ) × Ratio HI signal SHI signal – SLO signal
Notes
- See DC Voltage Accuracy. SHI and SLO: 10 V range only. SHI and SLO (sense) terminals referenced to LO input. Maximum voltage referenced to LO 12 V.
- Sense terminals on inputs are limited to 10 V range during ratio measurement. Add 0.0015% + 0.0005% per °C temperature coefficient to DCV percent of range accuracy when using the 100 V or 1000 V range on the input terminals.
