Setting-Up

Supplying Power to the VELOCICALC

The VELOCICALC 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 VELOCICALC 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.

Table 2-1 Typical Battery Life at 20°C

Air Velocity Alkaline NiCd

(ft/min) (m/s) (hrs) (hrs)

100 0.5 7.0 5.0

1000 5.0 4.4 3.5

9000 45.0 2.4 2.4

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 VELOCICALC is capable of displaying the measured values in several

different measurement units. The choices of measurement units are shown

in Table 2-2.

To change the display units on your VELOCICALC, refer to Appendix B, DIP

Switch Settings.

Using The Telescoping Probe

The telescoping probe, mounted on the side of the VELOCICALC, contains

the velocity, temperature, and humidity sensors (humidity sensor, Model

8360 and 8388 only). The probe is shipped pointing downward in the

stowed position. The probe can be used either mounted on the VELOCICALC

Chapter 2

or held in your hand. If the probe is to be used mounted to the VELOCICALC,

remove the probe from its stowed position, turn it 180°, and reinstall

(pointing upward) in the probe mounting brackets.

Extending The Probe

To extend the probe, hold the handle in one hand while pulling on

the probe tip with the other hand. Do not hold the cable while

extending the probe as this prevents the probe from moving.

Retracting The Probe

To retract the probe, hold the handle in one hand while pushing on

the probe tip with the other hand. If you feel the probe antenna

binding, pull gently on the probe cable until the smallest antenna

section is retracted. Collapse the rest of the antenna by pressing the

probe tip.

When using the probe, make sure the sensor window is fully exposed and

the red orientation dot is facing upstream.
