B-3 Specifications for AMPTEC 720A Battery Powered Version (720-BAT)*
Unless indicated separately below, all other specifications for the battery powered
version of the 720A match those listed in section B-1.
The 720-BATT power option for the 720A allows the user to power the meter with
rechargeable Nickel–metal hydride (NiMH) batteries. This power option comes with a
smart battery charger that has a red LED indicator when the meter is charging, and a
green LED indicator when the meter is fully charged. It is safe to leave the charger
