Model 2750 Multimeter/Switch System User’s Manual Getting Started 1-27
The following examples demonstrate how to include the function name in the command
string for configuration commands.
VOLT:RANG 10 ' Select 10V range for DCV.
RES:RANG:AUTO ON ' Enable auto range for W2.
CURR:DIG 4.5 ' Set DCI for 4½- digit resolution.
NOTE See Section 4 for details on setting range, digits, rate, bandwidth, and filter.
Exercise 1 — Basic DMM measurements
The exercise in Table 1-6 measures ACV on the 10V range and stores 15 readings in the
buffer.

Press RECALL > use edit keys to display readings. Press EXIT to exit
recall mode.
CALC1:DATA?
1. To avoid problems with remote programming, it is good practice to routinely clear the buffer (TRAC:CLE) at the beginning
of a program that performs multiple measurements (
SAMP:COUN >1). Restoring *RST or FACTory defaults does not clear
the buffer.
2. FACTory defaults place the instrument in a continuous measurement mode. *RST places the instrument in a non-
continuous measurement mode.
3. READ? triggers and returns 15 readings. These 15 readings are automatically stored in the buffer. See Exercise 4 and 5 for
more information on the READ? command.
4. Statistics for buffer readings are also stored in the buffer. For remote programming,
CALC1:DATA? only returns the read-
ings that were stored. It does not return buffer statistics.
CALC2 commands are used to calculate and return buffer statistics
(see Section 6 for details).
