The B&K Precision 2640 can be quickly recharged using Ni-MH
Rechargeable Batteries. The Recharged method of Ni-MH
Battery is controlled by the voltage of the Battery Cell and the
temperature of Battery. The external temperature of Ni-MH
Rechargeable Battery is gradually increased and then quickly
increased in some point of time. The B&K Precision 2640
closes charging quickly after checking the increased amount
(dT/dt) of external temperature of Battery for a unit time. Also, for
Battery protection, the recharging is compulsory closed by built-
in temperature sensor in case that the voltage of Battery Cell will
be increased to more than some specified level or the external
temperature of Battery will be going up to over 50C. For safe
usage, it is strongly recommended to use Ni-MH Rechargeable
battery, and please do not use in the place with high temperature
or high humidity during recharging.
