Yes, the ANKOM RF Gas Production System can monitor negative pressures. When performing oxygen consumption studies, a NaOH or strong base is used to scavenge the CO2 produced by the aerobic metabolism. This produces a negative pressure as the O2 is...
Possible causes include: A loose or disconnected wire from the pressure sensor A faulty circuit board To diagnose, unplug the pressure sensor connector from the circuit board and plug in a pressure sensor connector from a working module into the same...
There are several possible reasons for a cumulative pressure drop or negative pressure readings. Refer to RF Service Procedure Curve Identification Chart (RFS010) for curve illustrations. Possible causes include: A leak in the system. First, be sure...
Refer to RF Service Procedure Module Testing (RFS001). First, check the pressure within the module. If the pressure is approaching 10 psi, stop using this module and unscrew the module top immediately to avoid over-pressurizing the bottle. If the...
The pressure sensors are accurate to +/-0.04 psi. Fluctuations in cumulative pressure beyond this correspond to either a leak or a fluctuation in temperature when a module is attached to a sealed bottle. If you check the "valve open" check box, leave...
There is most likely a problem with the circuit board. Static discharge, high humidity/moisture contact with the circuit board, or physical damage from dropping, etc. may have caused the problem. Contact ANKOM Technology for further assistance.
First, be sure Synthetic Grease w/PTFE ( Part #: RF41 ) was used on the lip of the bottle and the lip of the septa port on bottles so equipped. This aids in making a tight seal. Second, inspect the gasket which seals the module top to the bottle. It...
The sensors are accurate to within +/-2°C over a range of 5°C - 60°C. To account for any Module-to-Module differences in temperature sensing capability, the GPM software provides a calibration screen that can be used before data recording begins...
