6.1 Battery

The 1521 has abuilt-in nickel-metal-hydride battery pack that can power the

instrumentfor about 18 hours before needing to be recharged. The battery will

dischargemuch more quickly if the display backlight is used often. The battery

chargeremaining or the message “External Power” is shownon the display

when the instrumentis switched on. The battery percentages are approximate

and should be used asgeneral guidelines when determining the length of

chargeremaining.

The battery is recharged in situ (whilein place) using the AC adapter that’s

provided.Plug the AC adapter into an AC socket of the appropriate voltage as

noted on theAC adapter (normally 115V, optionally 230V). Connect the DC

plug of theadapter into the DC input of the 1521 located on the right side. The
