Description:
When one of these commands is sent, the measurement 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 10HZ 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 or a reading has not been triggered, an error occurs when this command is sent.
