*CAL?
Only supported on DAQM907A multifunction module and internal DMM.
Calibration Query. Performs autocalibration (autocal) and returns the result.
Parameter Typical return
(none) +0 (no error), +1 (cal error)
Perform autocalibration: *CAL?
– This command is equivalent to SYSTem:ACALibration? ALL.
– Autocalibration takes just a few seconds to complete.
– Autocalibration compensates for internal drifts caused by time and temperature change. This can help to elim-
inate the errors to achieve a better performance.
– Following the autocalibration, the instrument returns to the instrument state that existed before the autocal-
ibration.
*CLS
Clear Status Command. Clears the event registers in all register groups. It also clears the error queue and alarm
queue.
Parameter Typical return
(none) (none)
Clear event register bits, error queue, and alarm queue: *CLS
*ESE <enable>
*ESE?
Event Status Enable Command and Query. Enables bits in the enable register for the Standard Event Register
group. An enable register defines which bits in the event register will be reported to the Status Byte Register group.
You can write-to or read from an enable register.
Parameter Typical return
Decimal sum of the bits in the register.
For example, to enable bit 2 (decimal value = 4), bit 3 (decimal value = 8), and
bit 7 (decimal value = 128), the decimal sum would be 140 (4 + 8 + 128).
Default: 0
+16
Enables bit 4 (decimal value = 16) in the enable register: *ESE16
– Use *PSC to control whether the Standard Event enable register is cleared at power on. For example, *PSC 0 pre-
serves the enable register contents through power cycles.
– *CLS clears the event register, but does not clear the enable register.
