4-165

4.19.24 :OCOMpensated

[:SENSe[1]]:RESistance:OCOMpensated Control offset compensation for Ω2

[:SENSe[1]]:FRESistance:OCOMpensated Control offset compensation for Ω4

Parameters = 0 or OFF Disable offset compensated ohms

= 1 or ON Enable offset compensated ohms

Formats :res:ocom

:fres:ocom

Defaults Power-up Saved power-on setup

*RST OFF

:SYSTem:PRESet OFF

Query :OCOMpensated? Query state of offset compensated ohms

Short-form format: :res:ocom?

:fres:ocom?

Response message: 1 (on) or 0 (off)

Description This command is used to enable or disable the offset compensated ohms feature. Offset com-

pensation is used to cancel the effects of offset voltages (such as thermal EMFs) when making

resistance measurements. Offset compensation is explained in detail in the front panel operation

section of this manual.

Programming example 10 OUTPUT 716; “:res:ocom on; ocom?”

20 ENTER 716; A$

30 PRINT A$

40 END

Line 10 Two commands in this program message; the ﬁrst enables offset compensation and,

the second queries the state of offset compensation.

Line 20 Addresses the Model 2001 to talk.

Line 30 Displays the state of offset compensation (1; on).

4.19.25 :SENSe2 subsystem

This subsystem is used read the digital I/O port.
