8.1 Exchanging batteries
The meter is supplied complete with two 1.5 V alkaline batteries (1N).
The meter has a two-step low battery indicator:
1) As soon as the batteries dip below the first charge level the battery icon in the display will light up.
The meter will continue to operate correctly, but the user is informed that the batteries should be
exchanged as soon as possible.
2) If the batteries are not exchanged, the battery will sooner or later reach the second alarm level. Normal
operation is no longer possible. At this state, the battery icon will flash, being the only thing that is still
visible in the display.
Tip
Do not throw batteries in the dustbin. Be sure to know and respect local regulations concerning
proper disposal.
