Pump Operation
The pump will operate automatically and does not need to be configured by the user.
The Falco has a built-in flow measurement system that governs the pump flow rate. In order to
establish an accurate flow rate, the pump will briefly stop every 30 seconds so that the flow
measurement system can establish an accurate baseline, this is called the flow measurement cycle.
If the flow measurement system detects that the flow rate is less than 80 ml/min the instrument will
display Error code 4 (Low System Flow). If the error persists for more than 3 flow measurement
cycles, the instrument will display Error code 6 (Flow System Blocked).
Calibration
The calibration options are accessed from Menu i1
INFORMATION
0 – 10 and 0 – 50 ppm Falco require 2 point calibration (Zero and Span 1). 0 – 1000 and 0 – 3000 ppm
Falco require 3 point calibration (Zero, Span 1 and Span 2).
For best performance, it is recommended to use a gas concentration near your alarm point. Before starting
the calibration process, please ensure you have the following equipment ready for use.
• Magnetic Actuator (part no. 873202)
• Hydrophobic Filter (part no. A-875417)
• Zero air
• Span gas
• Demand Flow Regulator (part no. 5/RD-01)
• Suitable tubing to connect gases to Falco
Zero
1) Local ambient air can be used for zeroing as long as it can be confirmed there are no target or
interferences gases present in concentrations exceed the lower detection limit of the Falco. If this
