Product Description
The Gas Analysis Computer is a multiple -function analyzer with integrated calculating functions.
Measurements are in accordance with the general regulations set forth by the BIMSchV (German
Regulations concerning the protection against harmful effects on the environment) at all kinds of
combustion plants within the framework of the monitoring of exhaust systems.

b) Measuring Procedure
Temperature Measurem.: K-type thermocouple (NiCr-Ni) for waste or flue gas temperature
K-type thermocouple (NiCr-Ni) for air or ambient temperature.
O2-Measurement :
CO-Measurement :
Draft Measurement :
Measuring Duration:
Electrochemical measuring cell.
Electrochemical measuring cell.
Piezo-resistive principle with internal temperature compensation.
Short-term memory measurements of max. 60 minutes are possible, followed by
a new calibration phase with ambient air.
Waste Gas Measurement : Via an external water separator and filter, the waste gas is fed to the sensors by
means of a gas feed pump. The pump capacity during the feeding phase is
approx. 0.8 l/min.
Sensor Calibration:
CO Concentration:
60 seconds after switching on the instrument.
CO sensor with H2 compensation, measuring range 0 - 4.000 ppm. Cutoff
threshold at 4.000 ppm for sensor protection via separate flush pump.
The remaining measuring values are not affected. The instrument is switched on
again at a value of 1.600 ppm.
Waste Gas Sampling:
By means of a waste gas sampling probe with retainer cone.

Damage of the filter and / or improperly fitted filter will greatly decrease o
eliminate the filter function and will eventually destroy pumps and sensors.
Check the microfilter for contaminations and replace as necessary.
If the pump capacity is reduced, exchange the diaphragm filter.
Make sure that threaded parts are straight when placed on and tighten them
moderately. Ensure sufficient sealing by means of O-rings.
Plug-type elements
and flanges:
Remove any gas residues. Grease with Vaseline.
Storage:
Store in a cool and dry environment at a temperature of approx. 60 °F (20 °C).

Information on Charging the Battery
PEM9002 is equipped with an NiCad storage battery. The service life and capacity of the battery are considerably
affected by the way the instrument is charged and used. In order to make the handling safer, the instrument has a
load management unit.
If an NiCad battery is, for example, always charged from 80% to 100% and never run down to the final discharge
voltage, it will lose some of its capacity. This is called the 'memory effect' , i.e. the battery remembers to what
extent it is run down.
A part of this memory effect is suppressed in the PEM9002 in that the battery cannot be recharged until it has
dropped below 60%.
Constant overcharging, too, has adverse effects on the NiCad battery. In order to prevent this, the charged
capacity, the voltage and the temperature of the battery are monitored in the PEM9002.
When predefined limits are exceeded, the charging process is interrupted. After the appropriate parameters
have been neutralized the charging process is automatically restarted again.
The service life of the NiCad battery can be significantly reduced when the instrument is operated at
temperatures below 40 °F (5°C).
The graphic charge-level indicator of the PEM9002 (10 battery symbols), which appears in the one-line status
display during the calibration phase, helps the user estimate correctly the capacity of the battery. The instrument
continuously measures the incoming and outgoing current during operation and charging. Under normal
operating conditions, the instrument should be operated until the battery is completely run down. When this
advice is followed, the actual capacity of the NiCad battery will definitely be shown on the display.
40
Storing the instrument is only recommended if the NiCad battery is fully charged. If the instrument has to be
stored for a prolonged time (approx. 2 weeks or longer) it is recommended to leave the instrument connected to
the charger. The same applies to low-level discharge of the battery: leave the instrument connected to the
charger for a longer period (up to 12 hours).
If the instrument is operated at temperatures exceeding the admissible temperature range, if the NiCad battery is
older, or if incomplete charging cycles (charging/discharging) are performed, it is possible that the display no
longer corresponds to the current status of the battery.
In this case the display is corrected as follows: discharge the battery by switching on until the instrument switches
off automatically. After that, connect the instrument to the associated charger and wait until the end of the
charging period (max. 4 hours). When the charging process is completed, the PEM9002 switches off
automatically.
Used or Dead Battery
For replacement of a Used or Dead battery, the analyzer has to sent back to the supplier / manufacturer.

Maintenance: - Empty the condensate reservoir after each measuring operation.
- Check the microfilter for contaminations and change as necessary.
- If the pump capacity decreases, change the hydrophob filter.
Attention! Damaging the filter or inserting it incorrectly will lead to invalid results!
Grease all tight or stiff parts with vaseline.
