- No signal
- No flow to probe
- Xevo G2-XS
FIX or WORKAROUND
- Verify that all fittings are tight.
- Purge reference fluidics at least five times.
- Verify flow to the probe when infusing.
The above issue has also been observed where the liner tube with capillary had been pushed down the PEEK nut inside the reference probe mount assembly. If this has happened, push the liner tube with capillary up to the required level and tightened the fitting well.
