Operation of Unit

Measurement Mode

• The meter has preset measures for all four gases to alert you when the concentration has become dangerous.

• The combustible gas measures the % of the lower explosive limit of 5. Meaning when the meter reaches 100% it is at its LEL. When this is reached the meter will alarm and flash XXX.

Maintenance      Wash with a cloth of mild soap and water Make a note on the board if -there is an issue with a meter -the meter needs bump tested/calibrated -the meter needs charged
