Alpine VOLUME 1.3 instruction manual Headset, WTG-1 Warble Tone Generator Option

-3-

4. HEADSET

This heavy duty headset is designed to block out intense sounds often found in industrial environments so that the user may easily hear the sounds received by the ULTRAPROBE. To use, simply plug the headset cord into the headset jack on the metered pistol housing, and place the headphones over your ears. If a hard hat is to be worn, it is recommended to use UE Systems' model UE-DHC-2HH Hard Hat Headphones which are specifically designed for hard hat use.

A.For those situations in which it is not possible or difficult to wear the standard headphones described above, UE Systems has two options available: 1. the DHC 1991 Earpiece which loops around the ear, and 2. the SA-2000 Speaker Amplifier which is a loud speaker that is compatible with the Ultraprobe headphone output jack.

5.WTG-1 WARBLE TONE GENERATOR (OPTION)

The WTG-1 Tone Generator is an ultrasonic transmitter designed to flood an area with ultrasound. It is used for a special type of leak test. When placed inside an empty container or on one side of a test item, it will flood that area with an intense ultrasound that will not penetrate any solid but will flow through any existing fault or void. By scanning with the Scanning Module, empty containers such as pipes, tanks, windows, doors, bulkheads or hatches can be instantly checked for leakage. This Tone Generator is a WARBLE TONE GENERATOR. This internation- ally patented transmitter sweeps through a number of ultrasonic frequencies in a fraction of a second to produce a strong, recognizable "Warble" signal. The warble tone prevents a standing wave condition which can produce false readings and provides for a consistency of testing in practically any material.

To use the WARBLE TONE GENERATOR:

1.Turn Tone Generator on by selecting either "LOW" for a low amplitude signal (usually recommended for

small containers) or "HIGH" for high amplitude. In high, the Warble Tone Generator will cover up to 4,000 cubic feet (121.9 cu. meters) of unobstructed space.

When the Tone Generator is on, a red light (located below the recharge jack in the front) flickers.

2. Place the Warble Tone Generator within the test item/container and seal or close it. Then scan the suspect areas with the Scanning Module in the Ultraprobe and listen for where the "warble" ultrasound penetrates.

As an example, if the item to be tested is the seal around a window, place the Warble Tone Generator on one side of the window, close it and proceed to scan on the opposite side.

To test the condition of the Warble Tone Generator battery, set to the LOW INTENSITY position and

listen to the sound through the Ultraprobe headphones. A smooth continuous warbling sound should be heard. If a "beeping" is heard instead, then a full recharge of the Warble Tone Generator is indicated.

To charge the Warble Tone Generator:

1.Use the recharger.

2.Plug the recharger cord into the recharge jack located on top of the front panel.

3.Plug the recharger into the local current supply

4.A complete charge will take 7 hours.

5.Since there is no memory problem, the Tone Generator may be charged after short intervals of use.
