Model DMM7510 7½ Digit Multimeter Application Manual
Using SCPI commands
This sequence of SCPI commands sets up and runs a single high-accuracy dc voltage measurement
when a device under test is connected to the DMM7510 and controlled remotely.
You may need to make changes so that this code will run in your programming environment.
Send the commands in the following table for this example application.
Command
*RST
:SENS:FUNC "VOLT:DC"
:SENS:VOLT:RANG 10
:SENS:VOLT:INP AUTO
:SENS:VOLT:NPLC 10
:SENS:VOLT:AZER ON
:SENS:VOLT:AVER:TCON REP
:SENS:VOLT:AVER:COUN 100
:SENS:VOLT:AVER ON

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 DMM7510
Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the DMM7510 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 when a
device under test is connected to the DMM7510.
After the code executes, the reading is displayed in the Instrument Console of Test Script Builder.
DMM7510-904-01 Rev. D March 2021
Section 2: Measuring dc voltage with high accuracy
Description
▪
Reset the DMM7510.
▪
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 GΩ 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; wait a few seconds for the reading.
