3.0 USING THE FLUE GAS ANALYZER
3.1 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 agent
immediately and keep the original packing. A label at the rear 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 the instrument for the first time it is recommended to charge the battery for 12 hours with the
instrument turned off.
3.2 Warnings
•
Use the instrument with an ambient temperature between -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 30 seconds to purge the pneumatic path from all traces of fumes.
•
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 remove all residues.
•
Remember to have the instrument checked and calibrated once a year in order to comply with the existing
standards.
3.3 Analyzer power supply
The instrument contains a high-capacity LiIon rechargeable battery.
The battery feeds the instrument any other probes or remote devices that may be connected. The instrument
runs for approximately 18 hours. 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.
ATTENTION: If the instrument is not going to be used for a long time we suggest recharging it at least
once every 2 months.
3.3.1 Checking and replacing the batteries
The status of the internal battery can be checked during instrument auto-calibration or even after, if necessary, by
pressing the information menu and accessing the “battery capacity” submenu. The menu displays the
battery’s residual capacity and voltage. 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 take advantage of this to the fullest
capability it is advisable to always use the instrument powered by the internal batteries and to charge it only when
it gives the battery flat message.
3.3.2 Use with external power pack
The instrument can work with the batteries fully discharged by connecting the external power pack provided.
Kindly note that while the battery is charging, some heat is generated which increases the instrument’s internal
temperature. This may lower the accuracy of some readings. The air temperature must be measured using the
air temperature probe since the internal sensor might lie at a different temperature with respect to ambient.
ATTENTION
THE INS TRUMENT IS SHIPPED WITH THE BATTERY HALF CHARGED SO I T IS ADVISABLE TO
CHARGE IT COMPLETELY BEFORE USE, TAKING 3 HOURS.
IT IS ADVISABLE TO CHARGE THE BATTE RY AT AN AMBIENT TEMPERATURE RANGING BETWEEN
50°F AND 85°F (10°C AND 30°C).
ATTENTION
IF THE INS TRUMENT HAS BEEN KEPT AT VERY LOW TEMPERATURES (BELOW OPERATING
TEMPERATURES) WE SUGGEST WAITING A WHILE (1 HOUR) BEFORE SWI TCHING I T ON TO HELP
THE SYSTEM’S THERMAL BALANCE AND TO PREVENT CONDENSATE FORMING IN THE PNEUMATIC
CIRCUI T.
