Page: 87 / 194

One of the "PVs" in the conductivity module, available for the customised "Ux" views, is "USP" (see
section 8.10.26).
- UNIT : Select the units in which the digital input, the analogue output, the physical parameter or a value sent
by a PLC (PVN), selected in the PV list above, is displayed.
- FILTER : Select the level of attenuation for the measurement signal on the digital input, the analogue output,
the physical parameter or a value sent by a PLC (PVN) displayed on the line selected. Three levels of attenu-
ation are proposed: "slow" (slow filtering has a high attenuation effect), "fast" (fast filtering) or "none" (no
filtering)
"Slow" filter "Fast" filter "No" filter
