Using Alkaline Batteries or
Individual NiMH rechargable
cells.
Use Duracell MN 1500 (1.5 volt,
2,850 mAH) alkaline battery or
equivalent. You may also use the
Duracell Ultra
or Energizer
Titanium
next generation batteries
which may provide up to 40% more
run time.
To use alkaline batteries or individual NiMH cells, remove
the battery cover, and if installed, remove depleted batteries
(or NiMH battery pack). If not already installed, insert a
battery Terminal Assembly (AM814.06) so that it is
positioned as shown in Figure 1-8. Insert three AA batteries
so that polarities match those indicated in the battery
compartment and secure the battery cover.
Note: It is important to set the
battery type to NiMH if individual
NiMH cells are being used to power
the instrument; otherwise there will
not be sufficient battery reserve to
preserve the memory once the
batteries are drained. Also, the
proper setting is important in terms
of the ability of the instrument to
accurately estimate the remaining
battery life
Indicate the battery type being used as follows;
Step 1 Press the
v key.
Step 2 Press the
c key
Step 3 Use the
dkey to highlight “Type”
Step 4 Press
ckey to activate the “Battery Type” menu.
Step 5 Press
dor ukeys to select the
appropriate battery type; alkaline or NiMH.
Step 6 Press the
c key to enter the selection,
followed by the
lkey to close the Power
menu.
If the rechargeable LD BAT010 battery pack is used, the
setting is overridden and assumed to be NiMH. The 824 will
automatically detect the presence of the pack, so the setting
can be left to what would most likely be used if individual
cells were to be used instead of the battery pack.
Note: The System 824’s “smart”
charging system is designed to detect
alkaline batteries and prevents
accidental charging.
If alkaline cells are installed but erroneously declared as
NiMH, the charger will start for several seconds, then will
detect that they are not NiMH. Charging will be terminated
and the battery type changed to alkaline. This safety
measure will prevent primary cells from being charged and
damaging the instrument due to leakage or explosion.
Nevertheless, it is inadvisable to ever attempt to charge
primary or non-rechargeable batteries.
Rechargable individual NiMH cells can also be charged in
an external rapid charger.
