The Apply Values procedure uses actual Process Variable input levels for calibrating the range of a

transmitter. To measure a liquid level for example, a sight-glass can be used to determine the minimum

(0%) and maximum (100%) level in a vessel. The PV is carefully adjusted to stable minimum and

maximum levels, and the LRV and URV values are then set by commands from the MC Toolkit.

For Honeywell HART devices, the procedure is given in Table 17, and for non-Honeywell Hart devices, it

is given in Table 21.
