Notes
• Batteries are not included in the standard supply.
• Battery operation is automatically overridden when the AC adapter is connected to the AC power supply.
• To prolong battery (disposable or rechargeable) life, it is advisable to activate «Auto shut» in the menu (see Section 4.3.7).
• All discarded batteries must be disposed of in an environmentally responsible manner. No attempt must be made to incinerate
or disassemble them.
• Models with the standard construction (AL, PL) cannot be operated with batteries.
2.3.3 Rechargeable battery operation "AccuModule" with internal charger (option for compact models only)
Models in this line with the compact (PL-S) models can also be operated with a battery charger integrated in the instrument. This
option is not part of the standard supply. It must either be ordered when the balance is purchased or be retrofitted later by a
METTLER TOLEDO dealer.
Always fit the protective cover over the weighing cell cone before removing the cover of the battery compartment on the
underside of the balance and inserting the NiMH rechargeable batteries.
Note: ensure correct polarity (as specified inside the battery compartment)!
Close battery cover again.
Charging NiMH batteries
Always charge NiMH rechargeable batteries fully before putting them into service. To do this, it is sufficient for the balance to be
connected to the power supply by the AC adapter. It is not necessary for the balance to be switched on.
If the balance is switched on during charging, the display flashes in waves. Once the batteries are fully charged, all three segments
of the symbol are permanently lit.
The condition of the rechargeable batteries is displayed at all times when the instrument is in use (just as with normal batteries).
Notes
• NiMH rechargeable batteries are included in the standard supply ("AccuModule").
• Battery operation is automatically overridden when the AC adapter is connected to the AC power supply.
If weighing with power supply connection > 48 h, the batteries must be removed (overheating hazard).
• To prolong battery life, it is advisable to activate «Auto shut» in the menu (see Section 4.3.7).
• All discarded batteries must be disposed of in an environmentally responsible manner. No attempt must be made to
incinerate or disassemble them.
• Models with the standard construction (AL, PL) cannot be operated with rechargeable batteries.
Caution
If the balance is equipped with an "AccuModule" internal battery charger, on no
account must normal (i.e. disposable, nonrechargeable) batteries be used! This
would constitute a fire and explosion hazard. Only rechargeable NiMH (nickel-
metal hydride) batteries may be used. Balances equipped with the internal charger
have the following warning notice on the cover of the battery compartment and on an
adhesive label on the underside of the balance: "CAUTION! Risk of Battery Explosi-
on if batteries are replaced with incorrect type. Replace only with type NiMH
RECHARGEABLE batteries".
If weighing with power supply connection > 48 h, the batteries must be
removed (overheating hazard).
