:CALCulate3

These commands are used to conﬁgure and control the CALC3 limit test.

[:DATA] <n>

:CALCulate3:LIMit [1]:UPPer[:DATA] <n> Specify upper limit1

:CALCulate3:LIMit [1]:LOWEer[:DATA] <n> Specify lower limit

Parameters <n> = -100e6 to 100e6 Specify limit value

DEFault Set speciﬁed upper limit to 1

Set speciﬁed lower limit to -1

MINimum Set speciﬁed limit to -100e6

MAXimum Set speciﬁed limit to +100e6

Description This command is used to specify the upper and lower limit for LIMIT1. The

actual limit depends on which measurement function is currently selected.

For example, a limit value of 1 is 1V for the volts functions (DCV or ACV),

1A for the current functions (DCI or ACI), 1

Ω on the ohms functions (2 or

4), and 1 (C, F, or K) for the temperature function (TEMP). A limit value is

not range sensitive. A limit of 1 for DCV is 1V on all measurement ranges.

:STATE <b>

:CALCulate3:LIMit[1]:STATE <b> Control LIMIT1 test

Parameters <b> = 0 or off Disable limit test

1 or on Enable limit test

Query :STATe? Query state (on or off) of limit test

Description This command is used to enable or disable the LIMIT1 test. When enabled,

the test sequence for limits will be performed every time the instrument per-

forms a measurement.

A failed indication (see :FAIL?) for LIMIT1 is cleared when the limit test is

disabled.

:FAIL?

:CALCulate3:LIMit[1]:FAIL? Read LIMIT1 test result

Description This command is used to read the results of the LIMIT1 test:

0 = Limit test failed

1= Limit test passed

The response message (0 or 1) only tells you if a limit test has passed or

failed. It does not tell you which limit (upper or lower) has failed. To deter-
