Condensate pad (Instruments without gas cooler)
Regularly check the condition of the condensate pad. It should be
changed:
- If it is darker than no. 3 on the soot scale
- If it has expanded to the "MAX" mark
To replace the condensate pad:
1. Remove hose from the cap and unscrew the cap
2. Unscrew the retaining bolt with spring
3. Replace old condensate pad with the new
4. Screw on retain bolt with spring again
5. Screw on cap and replace the hose to the cap
Sensors
The sensors are auto-zeroed in fresh air each time the analyzer is
turned on. Their state is constantly monitored by the instrument. New
sensors age as you use the analyzer due to normal wear and tear
(oxygen sensor) and due to measurements exceeding concentrations
beyond the nominal measurement range (toxic sensors). The output
values of the sensors are (menu
"Control"
):
O2
approx. 20000 mV
Others 0 mV (+/- 150)
If an error message is displayed during the auto-zero phase and does
not disappear after several retries, the instrument must be checked by
an authorized service center. The oxygen sensor must show a value
of >7000 mV, otherwise it must be changed by an authorized service
center.
The CO sensor is protected against over-saturation by an internal
program. If the limit value of 4000 ppm is exceeded, a second pump
switches on and floods the sensor with fresh air.
