Running
When the pump is switched on the timer will display the time elapsed in
minutes.
When the pump stops, the timer will display the elapsed time. If the pump is
restarted, the timer will begin to count from the time at which it stopped.
Alternatively the display can be zeroed using the reset button (4).
Charging
Each pump comes with a voltage detecting battery charger. This is preset to
give 500mA charge rate for sucient time to recharge the battery pack.
At this rate the battery will be fully recharged from at in approx 5 hours.
When the charger is plugged into the charging socket the red LED will be
illuminated.
When the battery is suciently charged the green LED will light. The charger
can be left connected for extended periods if required.
The charger also has a discharge facility built in which is triggered by the
yellow button at the front of the charger. Use of this is not essential but it can
be used to ensure a full discharge/charge cycle if required.
Our sampling pumps are designed to withstand the punishment of a long
and active working life. They are manufactured from 2.5mm thick aluminium,
cold formed and welded along all seams. This results is a case that is rigid,
non rusting and durable. The units are nished in a tough epoxy powder
coating which is resistant to minor damage.
Internally the pumps contain a high eciency, rotary vane vacuum unit
with a capacity of up to 3.0 litres/min of air through a standard 0.8 micron
membrane lter.
The ow is set from 1.0 litres/min to 3.0 litres/min by means of an electronic
control unit. This can be adjusted by turning the ow control screw found on
the underside of the unit (6)
Flow control is maintained to within + or - 3% of the set gure by an
electronic control unit which is epoxy sealed to protect against moisture,
heat and vibration.
Power is provided by an 8 cell 9.6v 2000mah battery pack, this allows for
approximately 8 hours sampling at 3.0 litres/min.
