Keithley 2700 User Manual

Model 2700 Multimeter/Switch System User’s Manual Getting Started 1-27
Basic DMM measurements — front panel inputs
NOTE See Section 3 for details on basic DMM operation.
The Model 2700 is shipped from the factory to power-up to factory defaults. The
instrument powers up to a setup that continuously measures DC volts. Some of the default
settings for the DCV function include auto range enabled, 6H-digit resolution, filter
enabled, and slow reading rate. These settings provide a good starting point and in many
cases, do not need to be changed.
“Starting-point” default settings are also provided for the other measurement functions.
Therefore, to perform basic measurements, simply select the desired function, and
“tweak” the setup (range, rate, filter, digits, etc.) as required.
For remote programming, the instrument is typically used in a non-continuous
measurement mode. In this mode, the user (via remote command programming) specifies
the number of measurements to perform. *RST defaults place the instrument in a non-
continuous measurement mode. Most of the other settings for factory and *RST defaults
are the same.
For remote programming, the following command is used to select function.
NOTE Items in brackets ([]) are optional and do not need to be included. Upper case
characters are required. Lower case characters are optional and need not be
included.
[SENSe[1]]:FUNCtion <func> 'Select measurement function.'
<func> ='VOLTage[:DC]' DCV
'VOLTage:AC' ACV
'CURRent[:DC]' DCI
'CURRent:AC' ACI
'RESistance' Ω2
'FRESistance' Ω4
'FREQuency' FREQ
'PERiod' PERIOD
'TEMPerature' TEMP
Each function can have its own unique setup configuration (i.e., range, digits, speed, etc.).
For example, the following command words select range and digits:
RANGe[:UPPer] <n> ' Specify expected reading.
RANGe:AUTO <b> ' Enable (ON) or disable (OFF) auto range.
DIGits ' Set display resolution; 3.5, 4.5, 5.5 or 6.5 (digits).
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 Ω2.
CURR:DIG 4.5 ' Set DCI for 4H-digit resolution.
NOTE See Section 4 for details on setting range, digits, rate, bandwidth and filter.
