use two nickel cadmium rechargeable
batteries, located in a battery case under the keypad. The
batteries are charged while they are in the pipettor by using the
power transformer included in the package. You can operate the
pipettor while it is recharging; or you can operate it solely with the
power transformer (without batteries). When fully charged, the
pipettor will perform over 1200 cycles at full stroke. The batteries
can be recharged approximately 400 times. To extend battery life,
the pipettor will turn off automatically if it is not used within ten
minutes.
Note: Spare batteries and external battery chargers can be
ordered through Matrix Technologies.
Battery charge is low when the battery symbol
appears on the display. The pipettor will continue to
function, but should be recharged at the earliest
convenient time.
Use the following steps to recharge the batteries:
1. Attach transformer. Attach the cable end of the transformer
into the pipettor. The plug receptacle is above the color ring.
Plug the transformer into the electrical outlet.
2. Recharge batteries. Recharge the batteries for 12-14 hours
to ensure a full charge. After the batteries have been recharged,
unplug the pipettor from the transformer. The pipettor is now
ready for use.
Note: Batteries hold their maximum charge if they are fully
discharged before recharging again. However, overnight
recharging is acceptable if the pipettor is in normal use during
the day.
CAUTION! Avoid excessive charging of the batteries when the
pipettor is not in use. Excessive charge to the batteries will
shorten the battery life and may damage the batteries.
