Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the device, readings will be
inaccurate and device could be damaged. We recommend the use of an MSA sample probe containing a special membrane
filter, permeable to gas but impermeable to water, to prevent such an occurrence.
During operation, a pump alarm may occur when the:
• Flow system is blocked
• Pump is inoperative
• Sample lines are attached or removed.
