The transmitter repeats the primary variable (in measurement
units) in each burst (e.g., 14.0 g/s, 13.5 g/s, 12.0 g/s).

PV current & % of range
% range/current
The transmitter sends the PV’s percent of range and the PV’s
actual mA level in each burst (e.g., 25%, 11.0 mA).
actual mA level in each burst (e.g., 25%, 11.0 mA).

The transmitter sends PV, SV, TV, and quaternary variable (QV)
values in measurement units and the PV’s actual milliamp
