13. FAQ
Where do I find important instru-
ment information?
How long is the life span of the
sensors?
Which sensors can I exchange?
The instrument shows the error
message „O
2
sensor 0 mV“!
The instrument shows the mes-
sage „Check required“!
The instrument shows the error
message „T-Gas“ oder „T-Air“!
The instrument shows wrong or
inaccurately CO
2
values!
In the menu „Control“ all important instrument infor-
mations are shown (e.g. accu voltage, sensor values,
unit number, next service date, operation hours etc.).
With the arrow keys stands you can switch to the
second page.
The life span depends on the operating hours and
the instrument equipment. The life span of the toxic
sensors (CO, NO, SO
2
, NO
2
) is affected by high gas
concentrations and a not sufficient purging. The life
span for these sensors amounts to on the average
between 4 and 6 years. The life span of the O
2
sen-
sor is independent of the operating hours and
amounts to approx. 4 years.
Please contact the next authorised service centre for
changing sensors.
The sensor must be renewed.
This message appears automatically every 12
months or after 250 operating hours. Note: This is a
recommendation to let check the instrument. The
instrument is however still ready for use.
Possible reasons could be:
- Cable is broken (at the plug)
- T-Air sensor is broken
- Thermocouple is broken
- Cable is defective
Note: The error messages can be ignored at the B by
pressing „Enter“. Calculations that depends on these
temperatures are not implemented.
Possible reasons could be:
- O
2
is defective (CO
2
values are calculated from
the O
2
values)
- Pump is not working correctly
- Leakage in the gas way
- condensate trap / gas cooler is clogged
