FEATURES

The Alnor® Velometer Jr.® Anemometer is a direct reading air velocity measuring instrument.

This precision instrument is ruggedly built and will serve for many years if given reasonable care.

You can use this instrument to measure air velocities fr om grilles and registers and to locate drafts. Balancing of a domestic heating installation is made simple when using the Alnor Anemometer.

Hold the instrument so the air blows directly into the calibrated orifice and read the velocity as indicated by the pointer.

Zero Adjustment

Velometer Jr.®

Hold the palm of your hands over the two openings in the sides of the Velometer Jr.

Anemometer and note whether the pointer indicates Zero. If not, turn the Zero Adjuster screw on the front of the case slightly until the pointer does read zero. (See fig. 1.)

Range Change

Change range by turning orifice fitting on double r ange i nstr um ents . (Small orifice for high range—large orifice for low range.) (See fig.1.)

ALNOR TYPE 8125 “AirGard®”

VELOMETER JR.® ANEMOMETER

The AirGard® Face Velocity Monitor is designed to indicate, by correlation, the average velocity at the face of a ventilation hood. To ensure that the average face velocity indicated by the AirGard is correct, the AirGard can be verified with a properly calibrated thermo-anemometer. Also, the AirGard

monitor should be mounted at a location where local drafts are

monitor should be mounted at a location where it

very low and the curved probe will not interfere with the work area. The calibration procedure follows four basic steps:

1. Make sure the AirGard

monitor attachments which were shipped with the instrument are available—the curved probe and flexible tube.

2. Zero the AirGard

monitor.

3. Measure the average face velocity of the hood using a properly calibrated thermo-anemometer.

4. Find the right location to mount the AirGard

monitor by moving it along the face of the hood until the meter indicates the same value as measured with the thermo-anemometer.

Step By Step Calibration Instructions

1. Connect the curved probe to the AirGard® monitor using the flexible tube.

2. Cover the inlet orifice on the left hand side of the AirGard

monitor

(the operator’s finger can be used for this purpose).

3. With the inlet covered, the AirGard

monitor should indicate zero fpm. If it does not, adjust the pointer to zero using the screw on the front of the case.

4. Using a properly calibrated thermo-anemometer, determine the velocity through the face of the hood by taking a detailed velocity traverse. Divide the face area of the hood into equal increments. A six-inch grid is recommended for an accurate traverse.

5. Position the AirGard

monitor at a location for mounting where local drafts are very low and the curved pr obe will not interfere with the work area.

6. Attach the probe to the hood so the open end is inside the hood and faces downstream.

7. Verify that the AirGard at the face of the hood in step 4. If the reading by the AirGard monitor does not match the reading measured in step 4, move the AirGard

monitor along the face of the hood until it indicates the

monitor reads the same velocity measured

same value as measured with the thermo-anemometer.

8. When the AirGard

monitor’s indication matches the value measured with the thermo-anemometer, mount it in place using the mounting screws and the curved probe using the fitting provided.

MAINTENANCE

Handle the Velometer Jr.® Anemometer as you would a watch. It is composed of precision parts and is carefully balanced and calibrated.

If due to accident, the Velometer Jr.

Anemometer requires repair, return to manufacturer for factory qual ity service. Other instrument laboratories may not have proper calibrating equipment.

A partially plugged orifice will result in a low reading and, therefore, we suggest occasional cleaning of the orifice. A toothpick is a good tool for this purpose. Do not use any wire or other hard tool for this purpose.

SERVICE INFORMATION

Service and Repair

Please return your Product Registration Card immediately. This allows us send you service reminders, special offers, and important information about your product.

Before sending your instrument for calibration or repair, you should call Customer Service. The Service Department will provi de you with the cost of service or calibration, Return Material Authorization (RMA) number, and shipping instructions.

Please have the following information available when you call:

Owner’s Name, address, and phone number Billing address, if different and applicable Instrument Name or Model Serial Number Date of Purchase Where Purchased

TSI recommends that you keep a ‘calibration log’ and keep all records of service on your instrument.

Instructions for Return

Send the instrument prepaid. Securely package your instrument in a strong container surrounded by at least two inches (5 cm) of suitable shock-absorbing material. Include the Purchase Order showing instrument model number, cost of service and/or calibration, and the RMA number. Mark the outside of the shipping container with the RMA number. This will expedite processing of your instrument when we receive it.

Please note that instruments received improperly marked or without an accompanying Purchase Order may be return ed at your expense. See back cover for factory addresses.

Damaged in Transit

All orders are carefully packed for shipment. On receipt, if the shipping container appears to have been damaged during shipment, the instrument should be thoroughly inspected. The delivering carrier’s papers should be signed n oting the apparent damage. DO NOT DISCARD THE BOX.

If the instrument itself has been damaged, a claim should be promptly filed against the carrier by the custo mer. The selling agent will assist the customer by supplying all pertinent shipping information; however, the claim must be filed by the insured. If the instrument is damaged beyond use, a new order should be placed with TSI while awaiting reimbursement from the carrier for the damaged instrument.

Call TSI directly for assistance if necessary .
