Setting-Up

Supplying Power to the VELOCICALC

The V

ELOCICALC 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
operate with either alkaline or NiCd
rechargeable batteries. Carbon-zinc batteries
are not recommended because of the danger of
battery acid leakage. The typical battery life for
alkaline batteries at 20°C at 150 ft/min is
10 hours.

Using the Optional AC Adapter

The optional AC adapter allows you to power

ELOCICALC from a wall outlet. When

the V
using the AC adapter, the batteries (if installed)
will be bypassed. The AC adapter is not a
battery charger.

ELOCICALC is designed to

The V
automatically power the instrument off after a
specified time. In velocity mode, the instrument
will power off after 15 minutes provided that
the velocity is zero and no keys have been
pressed during this time. In temperature mode,
the instrument will power off after 15 minutes if
no keys have been pressed. This feature can be
turned off if desired by switching DIP switch #5
to the OFF position. See Appendix B, DIP
Switch Settings.
