Chapter 1 Setup This chapter guides you through unpacking and installing batteries into your V . See ELOCI HECK chapter 2 for a detailed description of the digital ’s operating functions. ELOCI HECK Unpacking Carefully unpack the instrument and accessories from the shipping container. -
Page 10: Installing The Batteries
Installing the batteries Install batteries by loosening the screw in the battery access cover located on the back of the instrument. Insert four size AA batteries in the battery tube according to the polarity indicated on the instrument case under the battery access cover. Replace the battery access cover and tighten the screw. -
Page 11: Check Operation
Chapter 2 Operation ELOCI HECK This chapter thoroughly explains how to operate the V ELOCI HECK. Extending the probe The Model 8330 V contains a ELOCI HECK telescoping velocity and temperature measuring probe which is shipped in its collapsed position. To expose the probe to the flow for air velocity or temperature measurements, grasp the tip of the probe and pull firmly. -
Page 12: Measuring Temperature
NOTE: As you handle the probe, take care not to bump it against duct walls or other objects. The probe has been made as rugged as possible, but it can be damaged by careless handling. Measuring temperature Whenever you plan to measure both temperature and velocity, it is best to measure temperature first. -
Page 13: Measuring Velocity
Measuring velocity For highest accuracy, it is important with all s to properly align the probe to the ELOCI HECK flow. For accurate results, the measured air must flow through the sensor window at the end of the probe. HINT for measuring velocity: If the probe is left to warm up for more than a few seconds at velocities below 50 feet/minute (0.25 meters/sec) it will require more time to stabilize when it is... -
Page 14: Switching On The Power
Switching on the power using the ON/OFF Turn on the V ELOCI HECK switch. The V will display battery life ELOCI HECK for the first 5 seconds. This number represents the approximate percentage of battery life remaining, and will range from less than zero% for a low battery to something over 100% for a short time while the “surface charge”... -
Page 15: Selecting The Sensor Response
Selecting the sensor response The Model 8330 V has a ELOCI HECK FAST/SLOW response switch for setting the sensor response speed. In the slow response mode, the V displays the average velocity ELOCI HECK measured during the past 12 seconds. This is a running average, so the display is updated once a second. - Page 16 Table 2: Typical battery life* at three velocities Air Velocity alkaline life nickel- cadmium life (ft/min) (m/s) (hrs) (hrs) 2-1/2 1000 1-3/4 2000 10.0 1-1/2 * At 20°C The V continually monitors its battery ELOCI HECK supply voltage. Then the battery life falls below 15%, the battery indicator (BAT) in the upper left corner of the display will blink on and off.
- Page 17 If you do not install fresh batteries and the voltage falls below 2 volts, the display will go blank. ♦ Alkaline batteries are recommended for longest life, and the V battery life indicator ELOCI HECK will be most accurate with alkaline batteries. Operation ELOCI HECK...

Page 20: Cases
Cases If the instrument case or storage case needs cleaning, wipe it off with a soft cloth and isopropyl alcohol or a mild detergent. Never submerge the V ELOCI HECK Storage When storing the V for more than a ELOCI HECK month, it is recommended that you remove the batteries to prevent damage due to batteries leaking. -

Chapter 4 Troubleshooting Table 3 lists the symptoms, possible causes, and recommended solutions for common problems encountered with the V . If your ELOCI HECK symptom is not listed, or none of the solutions solves your problem, please contact TSI.

- Page 23 Since thermal sensors are sensitive to changes in air density and air velocity, all thermal anemometers indicate velocities with reference to a set of standard conditions. For TSI instruments, standard conditions are defined as 70°F (21.1°C) and 14.7 psia (101.4 kPa). Other manufacturers may use different values.
- Page 24 In some instances, actual air velocity rather than standard velocity may be of interest. To obtain the value for actual velocity, multiply your standard velocity readings (as indicated by the ) by the following density correction ELOCI HECK factor: ...
