Power Options

Internal Power—Batteries
Internal batteries are not user-replaceable. The approximate percentage of the power remaining in an internal battery is
displayed on the Home Screen when an instrument is connected to Win-Situ Software.
The instrument is powered by 3.6 VDC, supplied by a sealed, non-replaceable AA lithium battery. Battery life depends on
sampling speed. The battery typically lasts for 10 years or 2,000,000 readings, whichever occurs first.
When an instrument is wired to a data logger or PLC controller, power to the instrument is supplied by the data logger or
controller.

AC Adapter

The AC adapter provides 24 VDC, 0.75 A, AC input 100-250 V and includes a North American power cord. The TROLL Com
Communication Device includes an external power input port for connection to the AC adapter.
Description
AC Adapter 24 VDC
Use only In-Situ Inc.'s AC adapter. Damage to the instrument caused by the use of third-
party converters is not covered by the warranty.
External Power—External Battery Packs
External battery packs can significantly increase the life of an instrument, either for long-term deployments or to preserve an
aging instrument.

TROLL Battery Pack

The sealed, submersible TROLL Battery Pack supplements internal battery power when an instrument is used for fast,
frequent sampling or during long-term deployments. When this power source is connected, the instrument will use the
external battery source first and switch to the internal batteries when external battery power is depleted. Total battery life
depends on the sampling speed.
Description
TROLL Battery Pack
The sealed, submersible TROLL Battery Pack supplies 14.4 V. When this power source is connected, the Level TROLL will
use the external battery source first and switch to the internal batteries when external battery power is depleted.
