18. 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
“O2 sensor 0 mV“!
The instrument shows the message
“Check required“!
The instrument shows the error
message
“T-Gas“ or “T-Air“!
The instrument shows wrong or
inaccurately CO2 values!
In the menu
“Control“, all important instrument information is
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 in-
strument equipment. The life span of the toxic sensors (CO,
NO, SO2, NO2) 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 O2 sensor is independent of the operating hours
and amounts to approx. 2 years.
The following sensors are exchangeable:
- O2 sensor
- CO sensor (pre-calibrated)
- NO sensor (pre-calibrated)
- SO2 sensor (pre-calibrated / only together with
CO sensor
The sensor must be renewed.
This message appears automatically every 12 months or
after 250 operating hours. Note: This is a recommendation
to 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 by pressing
“En-
ter“. Calculations that depend on these temperatures are
not implemented.
Possible reasons could be:
- O2 is defective (CO2 values are calculated from
the O2 values)
- Pump is not working correctly
- Leakage in the gas way
- condensate trap / gas cooler is clogged
