  • Page 79: Null

    – Range changing is allowed for all math operations except for the Hold function. – For remote operation, refer to the CALCulate subsystem in the U3606B Programmer’s Reference. Null When making null measurements, also called relative, each reading is the difference between a stored (selected or measured) null value and the input signal.
