7.0 USING THE FLUE GAS ANALYZER
7.1 Preliminary operations
Remove the instrument from its packing and check it for damage.
Make sure that the content corresponds to the items ordered.
If signs of tampering or damage are noticed, notify the E INSTRUMENTS service center or distributor
immediately and keep the original packing.
A label on the back of the analyzer bears the serial number. This serial number should always be stated when
requesting technical assistance, spare parts or clarification on the product or its use.
E Instruments maintains an updated database for each and every instrument.
Before using for the first time we recommend you charge the batteries completely.
7.2 WARNING

Use the instrument with an ambient temperature between 23 and 113°F (-5 and +45°C).

When it has finished being used, before turning the instrument off remove the probe and let is aspirate ambient
clean air for at least 20 seconds to purge the pneumatic path from all traces of gas. Do not bypass the Post-
purge.

Do not use the instrument if the filters are clogged or damp.

Before putting the measuring probe back in its case after use, make sure it is has cooled down enough and
there is no condensate in the tube. It might be necessary to periodically disconnect the filter and the
condensate separator and blow compressed air inside the tube to eliminate all residue.

Remember to have the instrument checked and calibrated once a year in order to comply with the existing
standards.
7.3 Analyzer power supply
The instrument contains a high-capacity Li-Ion rechargeable battery.
The battery feeds the instrument, built-in printer and any other probes or remote devices that may be connected.
The instrument runs for approximately 18 hours if the printer is not used. Should the battery be too low to effect
the necessary measurements, the instrument can be hooked up to the mains via the power pack provided,
allowing operations (and analysis) to proceed.
The battery will be recharged whilst the instrument is being used.
The battery charging cycle takes up to 3 hours for a complete charge and finishes automatically.
If the instrument is not going to be used for a long time (e.g. summer) it is advised to store it after a
complete charging cycle; furthermore, perform a complete charging cycle once every 4 months.
7.3.1 Checking and replacing the batteries
The state of the internal battery can be displayed during the auto-calibration of the device and possibly later via
the information menu.
In the menu, the remaining battery power is displayed.
If battery charge appears to be low, let it discharge completely and then carry out a full 100% charge cycle by
connecting the instrument to the power pack for 3 hours.
If the problem persists, replace the battery pack with a E INSTRUMENTS original or contact the SERVICE
CENTER to carry out the necessary repairs.
The average life of the battery pack is 500 charging/discharging cycles. To exploit this characteristic to the full it
is advisable to always use the instrument powered by the internal batteries and to charge it only when it gives the
battery drained message.
The instrument can be left in stock for a period of time depending on the charging level of the battery; below there
is a table showing the correlation between stock time and charging level.
IF THE INSTRUMENT HAS BEEN KEPT AT VERY LOW TEMPERATURES (BELOW
OPERATING TEMPERATURES) WE SUGGEST WAITING A WHILE (1 HOUR) BEFORE
SWITCHING IT ON TO HELP THE SYSTEM’S THERMAL BALANCE AND TO PREVENT
CONDENSATE FORMING IN THE PNEUMATIC CIRCUIT.
THE INSTRUMENT IS SHIPPED WITH A BATTERY LEVEL LOWER THAN 30% AS
REQUIRED BY CURRENT AIR TRANSPORTATION STANDARDS. BEFORE USE PERFORM
A COMPLETE CHARGING CYCLE OF 8 HOURS.
IT IS ADVISABLE TO CHARGE THE BATTERY AT AN AMBIENT TEMPERATURE RANGING
BETWEEN 10°C AND 30°C.
