Response message: 1 (on) or 0 (off)

Description These commands are used to enable or disable Reference for the specified function. When enabled, the

displayed reading will include the programmed reference value (see :REFerence <n> and :ACQuire).

When disabled, the displayed reading will not include the reference value.
