points which have been programmed into the instrument during calibration.

From the menu, the user is prompted to press the up arrow key to view the readings: -

Sequential operation of the up arrow key shows in turn the alarm set points for each sensor. A typical display sequence for a 4-gas

Alarm settings for the Oxygen sensor - two settings

or FLAM 1.00 %VOL if in the volume mode

Alarm setting for the Flammable sensor - one setting

Alarm settings for toxic sensor 1, Hydrogen Sulphide - three settings

Alarm settings for toxic sensor 2, Carbon Monoxide - three settings

Important: - The Instantaneous Alarm settings must be greater than both the Short Term and Time-Weighted-Average/Long

Term exposure alarm settings. The Flammable sensor alarm setting cannot be set above 60% LEL.
