Error description Action
Oven

extremely high
Temperature sensor
failure
This is a critical problem. Turn off the power
of HGC. Contact a closer Yamatake office or
distributor.
Carrier Gas
pressure error
Carrier gas pressure
PV
PV<50kPa
or
300kPa<PV
1. Check the carrier gas supply pressure
setting (400+/-50kPa)
2. If the carrier gas PV is equal with carrier
gas supply pressure, this is a critical
problem. Turn off the power and stop the
carrier gas supply.
Contact a closer Yamatake office or
distributor.
Response
Factor error
Auto calibration fail.
RF percent deviation
limit< RF% DEV
Check the standard gas connection,
composition and supply.
This error continues until the correct
calibration take place.
Chromatogram
baseline error
TCD baseline out of
range
1. Check whether the carrier gas type and
purity is correct.
2. If the problem is not caused by the carrier
gas, a critical problem may have occurred.
Oven

Verify whether a sudden change has occurred
in the ambient temperature. Shield the HGC
to resume normal operation.

1. Check the carrier gas supply pressure
setting (400+/-50kPa)
2. Check the remaining gas cylinder
pressure.
3. If the problem is not caused by the carrier
gas, a critical problem may have occurred.
