4.19.15 :METHod <name>
[:SENSe[1]]:CURRent[:DC]:METHod <name> Specify measurement technique for DCI.
Parameters <name> = NORMal Normal DCI measurement technique
ICIRcuit In-circuit DCI measurement technique
Format :curr[:dc]:meth <name>
Defaults Power-up Saved power-on setup
*RST NORMal
:SYSTem:PRESet NORMal
Query :METHod? Query measurement technique
Short-form format: :curr:dc:meth?
Response message: NORM or ICIR
Description This command is used to select the DCI measurement technique. NORMal is used to make con-
ventional current measurements which are performed by breaking the circuit and placing the
ammeter in series with it.
The ICIRcuit selection allows you make an in-circuit current measurement of a wire or circuit
board trace. This measurement technique is performed by making four-wire INPUT connections
to the wire or trace (the AMPS input is not used). The instrument will then automatically per-
form a four-wire ohms offset compensated measurement and calculate the current. See front
panel operation for complete details on making in-circuit current measurements.
Programming example 10 OUTPUT 716; “:curr:dc:meth icir; meth?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first selects the in-circuit current mea-
surement method, and the second queries the selected method.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the selected measurement method (ICIR).
4.19.16 :SOURce <name>
[:SENSe[1]]:FREQuency:SOURce <name> Specify input source for FREQ.
Parameters <name> = CURRent Select current frequency input source
= VOLTage Select voltage frequency input source
Format :freq:sour <name>
Defaults Power-up Saved power-on setup
*RST VOLTage
:SYSTem:PRESet VOLTage
