Midas
®
Gas Detector
13-11
The Gas/Alarm Configuration page enables users to select the desired gas calibration. It also permits
setting alarm levels and other parameters. Additionally, alarms may be set to trigger on decreasing
concentration -- this is useful with oxygen.
An alarm delay of 0 to 60 seconds can be set up in order to give a programmable delay time before the
alarm signal is processed; this can be used to prevent nuisance alarms in certain conditions. Alarms can
be set latching which requires direct operator intervention to reset the alarm once activated. The User
Calibration Period is a reminder of when a calibration message will be broadcast by the Midas
®
via the
LCD display, analog or digital outputs. This can set to a custom period or if set to zero, no reminder will
be activated. The factory default is set for 6 months (180 days).
