1. Vacuum transducer reads a non-zero value with no flow going through the system
Resolution - Recalibrate the vacuum sensor using a NIST-traceable reference vacuum gauge
Resolution - Check the tubing connections between the inlet to the console and the vacuum
gauge
Resolution - Replace Main board
!
CAUTION
5.2.1 Vacuum transducer non-zero
1. H reading is too sporadicΔ
Resolution - Adjust ΔH damping settings in the console menu. If the value is jumping large
amounts, increase the damping band. If the value jumping small amounts, increase
the damping block size.
5.2.2 H reading is changing quickly and is difficult too readΔ
1. Console is not plugged into a working outlet of the correct voltage
Resolution - Ensure the console is powered off and then plug into a working outlet of the correct
voltage
5.2.3 Pump motor running abnormally
1. Console is not being operated upright
Resolution - Reposition the console to be standing upright
2. Console has a leak
Resolution - Check all fittings and tubing inside of the console for a leak, repair if necessary
3. Console scaling factor is not correct or is set at 0.0000 or 1.0000
Resolution - Find the scaling factor on the most recent full calibration and input this value into
the settings through the console menu option
