Rate of Change (RoC)
The rate of change is evaluated over a period of 24 hours to determine whether a warning is issued
or not. By default, RoCs are set at 0 for all gases. These default values can be modified to suit specific
applications.
To avoid false alarms, a minimum level is configured for the rate-of-change alarm to be considered.
Only when a gas is above the gas RoC trigger level will a rate-of-change warning or alarm condition be
raised.
To configure these settings:
1 From the CoreSense M10 dashboard, click Settings . The Settings page appears.
2
Click
Sensor settings
. The Sensor settings page appears.
3
Click the arrows adjacent to
DGA
