DX4040 INSTRUCTION AND OPERATING MANUAL (E2.04)
4.3.2
Power Supply
Only a Gasmet specified battery or a Gasmet specified AC/DC PSU must be used
with DX4040 analyser.
4.3.2.1 Battery
The DX4040 analyser uses 11.25 VDC state of the art lithium ion rechargeable battery
with SMBus features and LED display. It has a rated energy of 153 Wh that leads to a
functioning time of two and a half hours depending of external temperature. The lower
the temperature is, the shorter the functioning time especially with temperatures below
5 °C.
As the available energy per hour of the battery is quite high, this battery is submitted to
strict legislation regarding battery shipping. Those batteries benefit of a transportation
certificate specifying that the batteries meet the requirements of the UN
Recommendations on the transport of dangerous goods, Part III, sub-section 38.3.
Depending upon the transportation, the batteries are shipped according to the country
of shipment, rules on dangerous goods. The shipper is solely responsible for proper
packaging of the batteries. It is strongly advised to contact the shipping company in
your own country before shipping battery in order to ensure correct and safe shipping.
The battery is compliant with the Smart Battery standard. Charge indicator LEDs are
visible on the front end of the battery as well as a push button. Use the push button in
order to monitor the status of charge of the battery. Batteries can be charged or
discharged at the same temperatures than the analyser operating temperature 0 - 40
°
C). Batteries can be charged inside the analyser in the same time than the analyser is
functioning using the AC/DC PSU at the expense of a longer charge time as the supply
is split in between the analyser and the battery charge. When the analyser is switched
off and the battery needs to be fully charged, the charge time is less than five hours.
This charge time is more or less similar on the entire operating temperature range.
Batteries are recommended to be charged at ambient temperature. If a battery is too
cold (less than 0
°
C) or too warm (more than 50
°
C), charge of the battery is discarded
by the embedded charger in order to prevent possible damages to the battery. If the
battery voltage is too low (below +9 V) and the DX4040 is switched ON only under
battery mode, the analyser will remain off in order to prevent voltage depletion and
damage to the battery. For best performance, keep the battery within 15 - 50 % of full
charge for long-term battery storage.
