Battery Replacement
When the “LO BAT” indication shows on the display, the battery should be re placed.
The unit will continue to operate for a few hours. The Ampstik is powered by a single
9V battery. To re place the battery, remove the four screws on the battery cover at the
rear of the unit. Carefully insert a screwdriver blade in the notch and pry the cover out,
being careful not to damage the cover seal. Pull the bat tery out of the com part ment
and sep a rate the battery from the battery connector. To avoid breaking the battery
leads do not pull on the battery only. Install a fresh battery and reinsert the battery in
its com part ment. Reinstall the cover by gently press ing it into place while pulling out
on the edges of the com part ment, and reinstall the four cover screws. Take care to
avoid over tight en ing the screws. Always reuse the screws provided and do not damage
or lose the o-ring seal on each screw.

The Ampstik can be cleaned by wiping with a small amount of alcohol on a rag.
