EI-5 Manual Rev A 15
Caution: Repair and maintenance beyond that described in this manual
should only be performed by qualified personnel. Return to qualified service
centre for column replacement.
Batteries: If the “Low Battery” LED indicator is solid and bright red, the
batteries require replacing. Four (4) “AA” cells power the instrument. Replace
the batteries by sliding open the battery access panel at the bottom of the
instrument case. Remove old batteries and replace with new batteries.
Observe proper polarity! Check condition of new batteries by observing
the “Low Battery” indicator.
Sensor: The sensor operates at a very low temperature and may never
require replacement. The Figaro 2610 sensor can only be calibrated to a
range of sensitivity and not to a fixed point. It is advisable to return the unit
to an authorized service depot for sensor replacement, as other adjustments
may be necessary to match the sensor to the instrument.
Separation Column: The separation Column included in the instrument
is constructed using Silica Sand. The column should not be disassembled
in any way. It is advisable to return the unit to an authorized service center
for column replacement.
General Maintenance: Keep the instrument clean and preferably stored
in the carrying case supplied with the instrument. As with any instrument,
extremes of temperatures and humidity should be avoided as much as 10
possible. It is not advisable to leave the instrument in an unheated vehicle
night after night in northern climates (winter conditions). Do not subject
the instrument to concentrations of heavy hydrocarbons (hexane, gasoline
fumes, etc.), as the separation column will become contaminated.
