Also included with your shipment are two C-type batteries, a recharge kit in a plastic case

Locate the instrument close to the sample being analyzed, and to the Personal Computer

Make sure you install a fully charged set of batteries, or connect the instrument to an
external power source (see “External Power Supply (optional)” on page 11), before
