Model 2100 6 1/2-Digit Resolution Digital Multimeter User’s Manual Appendix B: Remote Interface Reference
The command syntax shows most commands (and some parameters) as a mixture of upper and
lowercase letters. The uppercase letters indicate the abbreviated spelling for the command. For
shorter program lines, send the abbreviated form. For better program readability, send the long
form. For example, in the above syntax statement, VOLT and VOLTAGE are both acceptable
forms. You can use upper or lowercase letters. Therefore, VOLTAGE, volt, and Volt are all
acceptable. Other forms, such as VOL and VOLTAG, will generate an error.
Braces ( { } ) enclose the parameter choices for a given command string (do not type the braces in
the command string).
A vertical bar ( | ) separates multiple parameter choices for a given command string.
Triangle brackets ( < > ) indicate that you must specify a value for the enclosed parameter. For
example, the above syntax statement shows the range parameter enclosed in triangle brackets
(do not type the brackets in the command string). You must specify a value for the parameter (such
as "VOLT:DC:RANG 10").
Some parameters are enclosed in square brackets ( [ ] ). The brackets indicate that the parameter
is optional and can be omitted (do not type the brackets in the command string). If you do not
specify a value for an optional parameter, the multimeter chooses a default value.
Using the MIN and MAX parameters
You can substitute MINimum or MAXimum in place of a parameter for many commands. For
example, consider the following command:
Instead of selecting a specific voltage range, you can substitute MIN to set the range to its
minimum value or MAX to set the range to its maximum value.
Querying parameter settings
You can query the current value of most parameters by adding a question mark ( ? ) to the
command. The following command sets the sample count to 10 readings:
"SAMP:COUN 10"
Then you can query the sample count by executing:
"SAMP:COUN?"
You can also query the minimum or maximum count allowed using the following commands:
"SAMP:COUN? MIN"
"SAMP:COUN? MAX"
