Notes:
1. Default ranges have been selected based upon recommended exposure limits set around the world.
2. Where ranges significantly above the recommended defaults are needed select a gas cal point
near to the required alarm point or between 30 and 70% of full scale. Consideration must be given
to providing adequate ventilation of the calibration gas and ensure there is no exposure of the user
to toxic levels of gas.
For details of how to change the configuration for full scale range, calibration gas level, calibration
interval, inhibit current & timeout and access password refer to section 12.
