To aid in troubleshooting, the operator may choose
to reset the gas detector to its default state by
holding both the UP and DOWN buttons for 5
seconds while in the Diagnostics Menu. All settings,
including the alarm setpoint, gas adjustments, the
selected gas curve, calibration data, the Modbus
address, etc. revert to specific default values after a
reset.
IMPORTANT: Calibrations on either gas-specific or
broadband models are lost after a reset. This
returns the gas detector to an uncalibrated
condition. See parameter P.-17 for information on
how to recalibrate the gas detector.
See Section 8 for a complete list of codes and
details on the reset option.
