Parameters
Query
Description
An alternate way to perform the calculation and read the result is by using the query form of the
command (:IMMediate?). When this command is sent, the calculation is performed and the
result is queried.
This example assumes that there are readings stored in the buffer and CALC 2 is enabled:
PRINT #1, "output 16; :calc2:form max"
PRINT #1, "output 16; :calc2:imm?"
PRINT #1, "enter 16"
:DATA?
:CALCulate2:DATA? Read CALC 2 result
This query command is used to read the result of the CALC 2 operation. If CALC 2 is disabled
or NONE is selected, the "raw" reading will instead be read.
Note that this command does not initiate a calculation. This command is used to simply read the
result of the last calculation.
PRINT #1, "output 16; :calc2:data?"
PRINT #1, "enter 16"

:CALCulate3

This Calculate subsystem is used to configure and control the limit tests (LIMIT 1 test and LIM-
IT 2 test). See paragraph 2.12.5 for details on limit tests.

These commands are used to set the upper and lower limits for LIMIT 1 and LIMIT 2. 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
