Introduction
Charging the battery pack
A USB cable is included with the ProDSS to charge the instrument battery pack and connect the instrument to a PC.
The instrument battery pack can be charged from the AC power adapter, directly from a computer USB connection or
from an external, portable USB battery pack (sold separately, see
ProDSS accessories on page 76 ).
Plug the USB connector into the AC power adapter, computer USB connector or external USB battery pack, then plug
the micro USB connector into the ProDSS instrument (
Figure 1 ).
NOTE: The ProDSS internal charge controller only allows the battery pack to be charged if the temperature is
between 0 and 45 °C (32 and 113 °F).
WARNING: Charge the battery pack in an open area away from flammable materials, liquids, and surfaces. Read
Rechargeable Lithium-Ion battery pack safety warnings and precautions on page 79 .
The ProDSS will charge faster when plugged into an AC outlet for charging rather than a PC’s USB port. For the
instrument to recognize that it is using AC power, you must start charging the ProDSS while on. After the instrument
recognizes it is being charged, it can be turned off to finish charging.
When using the AC adapter, it takes approximately 14 hours to charge the ProDSS battery when the instrument is
turned off during the charge. The amount of time required to completely charge the battery pack when the ProDSS is
initially turned on during the charge is approximately 9 hours.
