Troubleshooting:
• Check that the Nomo extension’s Luer connector is tightly connected to the gas
regulator.
• Check that the float of the rotameter lies above the first line during the entire test
and that you allow a minimum of 30 seconds of stabilization before noting the gas
values.
• Check the expiration date and the storage condition for the gas cylinder. Also
make sure that the cylinder´s gas pressure is sufficient, i.e. the pressure indicator
on the manometer is not within the red mark (see figure 1-16).
• Leave the NomoLine ISA system running with the NomoLine ISA Maintenance Kit
connected for a minimum of 15 minutes before running the gas span check again.
