Alarm hysteresis screen
This screen indicates when the Pioneer considers an alarm condition passed. The alarm
hysteresis feature helps prevent readings that are near an alarm setpoint from frequently
going into and out of alarm (relay chattering). For example, if the alarm hysteresis setting
is 2.0% of fullscale, fullscale is 10.0 ppm, and the alarm 1 setpoint is 3.0 ppm; then the
Pioneer will not consider the alarm 1 condition “passed” until the reading goes below 2.8
ppm. You can choose from a range of 0.0% to 10.0% of fullscale (in 0.1% increments). The
default setting is
2.0% .
