INSTrument
:DMM {OFF|ON}
:DMM?
Disable or enable the internal
DMM. When you change the state of the
internal
DMM, the instrument issues a Factory Reset (*RST command).
The :DMM? query returns the state of the internal DMM. Returns “0”
(disabled) or “1” (enabled).
INSTrument:DMM:INSTalled?
Query the instrument to determine if the internal
DMM is installed.
Returns “0” (not installed) or “1” (installed).
DIAGnostic:DMM:CYCLes?
Query the cycle count of the three backplane relays on the internal DMM.
These relays open or close when a function or range is changed on
a module. Returns three numbers indicating the cycle count on relays
“1”, “2”, and “3” (which correspond to relays K102, K103, and K104
respectively).
DIAGnostic:DMM:CYCLes:CLEar {1|2|3}
Reset the relay cycle count on the specified internal
DMM relay.
Note that the instrument must be unsecured to reset the cycle count
(to unsecure the instrument, see the calibration section on page 292).
DIAGnostic:RELay:CYCLes? [(
@<ch_list>)]
Query the cycle count on the specified channels. In addition to the
channel relays, you can also query the count on backplane relays and
bank relays. Note that you cannot control the state of these relays from
the front panel but you can query the count. For more information on
channel numbering and layout, refer to “Module Overview” starting on
page 163.
DIAGnostic:RELay:CYCLes:CLEar [(
@<ch_list>)]
Reset the cycle count on the specified channels. Note that the instrument
must be unsecured to reset the cycle count (to unsecure the instrument,
see the calibration section on page 292).
