reads this value and records it as the channel’s
Sensor Life
.
Sensor Life
is stored in the
SafeGuard Controller’s modbus database and displayed as a bar-graph in the Sensor Info
screen (see section 2.3.6). It is a useful tool for planning sensor replacement schedules.
2.2.5 LINEARIZATION
MENU
The linearization menu allows each channel to have its own linearization curve stored in
the SafeGuard Controller’s non-volatile memory. Input versus output points must be
entered in
percent of full scale
values. This means if the range is 0-200 ppm H2S then
100 ppm is 50% of full scale. Zero input will provide a zero output and 100% input a
100% output. Nine intermediate points may be entered to define the curve.

ASCII fields. Eunits should define the units of measure for
what this channel is to display.
Measurement Name
should describe the source of this
data in the user’s terminology. Section 2.1.1 of this manual describes how to use the
front keypad to modify these fields.
