Model DMM6500
6½ Digit Multimeter User's Manual Section 6: Measuring 4-
wire resistance with offset compensation
DMM6500-900-01 Rev. B / August 2019 6-5
Using SCPI commands
This sequence of SCPI commands measures the resistance of a device or component.
You may need to make changes so that this code will run in your programming environment. In the
following table, the SCPI commands have a light gray background.
Send the following commands for this example application:
Commands Descriptions
*RST
:SENS:FUNC "FRES"
:SENS:FRES:RANG: AUTO ON
:SENS:FRES:OCOM ON
:SENS:FRES:AZER ON
:SENS:FRES:NPLC 1
:READ?
 Reset the DMM6500.
 Set the function to 4-wire measurement.
 Enable autorange.
 Enable offset compensation.
 Enable autozero.
 Set NPLC to 1.
 Read the resistance value.
Using TSP commands
The following TSP code is designed to be run from Keithley Instruments Test Script Builder (TSB).
TSB is a software tool that is available from tek.com/keithley
. You can install and use TSB to write
code and develop scripts for TSP-enabled instruments. Information about how to use TSB is in the
online help for TSB and in the “Introduction to TSP operation” section of the Model DMM6500
Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the DMM6500 uses the SCPI command set. You must select the TSP command set
before sending TSP commands to the instrument.
To enable TSP commands:
1. Press the MENU key.
2. Under System, select Settings.
3. Set the Command Set to TSP.
4. At the prompt to reboot, select Yes.
This sequence of TSP commands initiates one resistance reading. After the code is executed, the
data is displayed in the Instrument Console of Test Script Builder.
