Pack
A dead battery will be fully recharged in 4.5 hours. The
Nicad battery pack has a LED charge status indicator to
show the current status when connected to the charger.
The LED indicator has five states as follows:
• Solid Amber: Fast charge in progress
• Solid Green: Fully charged, in trickle
charge mode
• Flashing Green: Battery too hot/cold to be
fast charged, in trickle
charge mode
• Flashing Amber: Instrument running, fast
charge mode
• Alternating Green/Amber: Trouble, electrical problem
in battery pack
A fully charged Nicad battery pack will typically operate a
four-gas configured ATX612 for up to 16 hours. When the
instrument is in the normal viewing mode, an eight-
segment battery status indicator continuously displays the
battery condition. Each segment represents approximately
2 hours of operating time. When the battery is fully
discharged, the display will read BATTERY FAIL and the
instrument will emit a short beep once a second (See
Section 4.6.6). Turn off the instrument and recharge the
battery pack when BATTERY FAIL appears.
WARNING: Recharge Nicad battery pack only in a
non-hazardous location.
