Setting-Up
Supplying Power to the V
ELOCI

ALC
The V
ELOCI
C
ALC
can be powered in one of two ways: four size AA batteries
or the optional AC Adapter.
Installing the Batteries
Insert four AA batteries as indicated by the diagram located on the
inside of the battery compartment. TSI ships the unit with alkaline
batteries. The V
ELOCI
C
ALC
is designed to operate with either
alkaline or NiCd rechargeable batteries. Carbon-zinc batteries are
not recommended because of the danger of battery acid leakage.

Using the AC Adapter
When using the AC adapter, the batteries (if installed) will be
bypassed. The AC adapter is not a battery charger.
Selecting the Display Units
The V
ELOCI
C
ALC
is capable of displaying the measured values in several
different measurement units. The choices of measurement units are shown
in Table 2-2.
