Testing Alarm Indicators
Under normal-operation mode and non-alarm conditions, the backlight can be tested by turning the
instrument on. If you perform a bump test, the buzzers and LEDs are tested.
If any alarm does not respond, check alarm settings to make sure all alarms are enabled. If any alarms
are enabled but not functional, the instrument should not be used.
Calibration Status
If any sensor requires calibration, then you are alerted on the screen during startup, and the sensor
requiring calibration is shown in red:
Calibration is required if:
The sensor module has been replaced with one whose calibration is overdue.
The defined period of time between calibrations has been exceeded, according to the policy
set for the instrument.
If you have changed the calibration gas type without recalibrating the instrument.
The sensor has failed a previous calibration.
Bump Status
If any sensor requires a bump test, then during startup, the screen displays "Bump Overdue," with a
list of those sensors shown in red:
A bump test is required if the defined period of time between bump tests has been exceeded. This
interval is set by an administrator using Device Configurator.
