Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 15: SCPI Measurement Commands
When :READ? is executed, its operations will then be performed. In general,
another :ABORt is performed, then an :INITiate, and finally a FETCh? to acquire
the readings. See “READ?,” page Section 15-4, for more details.
NOTE The :FORM:ELEM command controls the reading source. To access channel 1 readings,
send :FORM:ELEM CURR1 before sending :MEAS?. To access channel 2 readings,
send :FORM:ELEM CURR2 before using :MEAS?.
When :MEASure? is sent, the source turns on and a single measurement is
performed. If automatic output-off is enabled (:SOURce1:CLEar:AUTO ON or
:SOURce2:CLEar:AUTO ON), then the corresponding output will turn off after the
measurement is completed. If automatic output-off is disabled
(:SOURce1:CLEar:AUTO OFF or :SOURce2:CLEar:AUTO OFF), then the
corresponding output will remain on after the measurement is completed.
WARNING With automatic output-off disabled, the output will remain on after the single
source-measure operation is performed. Beware of hazardous voltage that
may be present on the output terminals.
