MODEL 300 COMBUSTION ANALYZER3-18 Instruction 24-92233.9 CHARGING THE BATTERY PACKIf the analyzer is powered by a battery pack, charge the pack as describedbelow (also see Fig. 3-8).A fully charged battery pack will run the analyzer through at least 200combustion efficiency tests (6 hours minimum); although, typical operat-ing time is between 12–16 hours. When the battery pack becomes dis-charged, its BATTERY STATUS LED turns off. The analyzer, however,will continue to operate for approximately 1 hour; after which, the pack’sinternal circuitry completely shuts down the analyzer to prevent a deepdischarge of the pack’s lead-acid batteries.Recharge the battery pack whenever its BATTERY STATUS LED nolonger lights. The pack, however, can be recharged at anytime; you don’tneed to wait until the LED goes out before recharging. A circuit withinthe charger prevents overcharging by automatically switching to a tricklecharge whenever the pack becomes fully charged.Recharge the battery pack by first turning OFF the pack and connectingthe charger that was supplied with the analyzer to the pack’s CHARGERjack. Plug in the charger and allow the battery pack to charge a minimumof 16 hours if the pack was completely discharged. The instrument maybe run indefinitely directly off of the recharger.Figure 3-8.
