This section explains the details of the operation of the 1521 with its compo

nents and accessories.
6.1 Battery
The 1521 has a built-in nickel-metal-hydride battery pack that can power the
instrument for about 18 hours before needing to be recharged. The battery will
discharge much more quickly if the display backlight is used often. The battery
charge remaining or the message “External Power” is shown on the display
when the instrument is switched on. The battery percentages are approximate
and should be used as general guidelines when determining the length of
charge remaining.
The battery is recharged in situ (while in place) using the AC adapter that’s
provided. Plug the AC adapter into an AC socket of the appropriate voltage as
noted on the AC adapter (normally 115V, optionally 230V). Connect the DC
plug of the adapter into the DC input of the 1521 located on the right side. The
battery will be charged as necessary whether or not the instrument is switched
