Model DMM6500
6½ Digit Multimeter User's Manual Section 5: Measuring DC voltage with
high accuracy
DMM6500-900-01 Rev. B / August 2019 5-5
Using SCPI commands
This sequence of SCPI commands makes a single high-accuracy DC voltage measurement.
You may need to make changes so that this code will run in your programming environment. In the
table, the SCPI commands have a light gray background.
Send the following commands for this example application:

Reset the DMM6500
Set the instrument to measure DC voltage
Set the measure range to 10 V
Set the input impedance to automatic so the instrument
selects 10 Ω for the 10 V range
Set the integration rate (NPLCs) to 10
Enable autozero
Set the averaging filter type to repeating
Set the filter count to 100
Enable the filter
Read the voltage value; it is a few seconds before the
reading is returned
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 makes a single high-accuracy DC voltage measurement. After the
code executes, the data is displayed in the Instrument Console of Test Script Builder.
