Details
When one of these commands is sent, the measured input signal is acquired and established as the
reference value. This command is typically used to zero the display. For example, if the instrument is
displaying a 1nA offset, sending this command and enabling Reference zeroes the display.
This command is functional only if the instrument is on the specified measurement function. Sending
this command while in any other function causes an error. Also, if the latest reading is overflowed
("OFLO") or a reading has not been triggered ("----"), an error occurs when this command is sent.
The :ACQuire command is coupled to the :REFerence <n> command. See the description for the
:REFerence <n>
