Page 5: Description
Description General The new HL 5000 Leak Locator is designed to facilitate the implementation of a complete water leak detection program - from the preliminary survey, to pre-location, to pinpointing. Although designed with the water utility in mind, the HL 5000 can also be used for finding leaks in any pipe distribution network from which pressurized liquid creates sound when escaping from a leak. -
Page 6: Construction
Construction The construction of the HL 5000 is solid. The durable plastic housing of the receiver is water resistant and built to withstand normal field operation. The comfortably spaced soft keys on the front of the control panel allow even a gloved operator to easily navigate between features. -

Page 8: Getting To Know The Hl 5000
Before using the HL 5000 , it is recommended that you take some time to become familiar with the unit and its features. 2.1 HL 5000 Controls Fig 1 : HL5000 Standard/Pro control panel 2.2 Connection of Components and Accessories... -
Page 9: Battery Compartment
Fig 2 : Side view left and right with connections Battery Compartment To access the battery compartment, loosen the two screws on the underside of the unit and remove the base plate (Fig.3). Eight AA batteries power the HL 5000 . When installing or replacing batteries in the unit, be sure that the positive and negative terminals of each battery are correctly aligned. -
Page 10: Automatic Battery Monitoring
2.4 Automatic Battery Monitoring While the HL 5000 is in operation, the battery level is monitored continuously. The battery symbol in the top right of the display will begin to flash when there are approximately 4 hours of battery life remaining. 2.5 Backlight With the equipment on, briefly push the on/off button The backlight for the display will be activated / deactivated. -
Page 11: Pam U
2.6.2 PAM U 40 Universal Microphone The PAM U 40 is a piezo-electric microphone that was developed primarily as a contact and/or survey microphone. With the use of various adapters, however, it is very effective in nearly all leak detection situations. Sensor Rod Configuration: This configuration allows the operator to quickly survey the distribution system for leak sound by... -
Page 12: Headphones
Caution: Whenever possible, grasp and pull the microphone itself not the cable when removing the microphone from a magnetic contact point. This will help prevent possible damage to the microphone cable Headphones The supplied headphones with ambient sound insulation come standard with the HL 5000 . These electro-dynamic headphones provide excellent reproduction of leak sounds while blocking out ambient sound to 85 dB. -
Page 13: Operation
Operation Connection and Removal of Attachments Always make sure that the HL 5000 is off when connecting or removing the headphones or the microphone. 3.2 Turning the Unit On After attaching both a microphone and the headphones, press the On/Off button on the control panel of the unit. -
Page 14: Headphone Volume And Microphone Amplification (Gain)
Fig 8 : Main Screen with Main Menu Headphone Volume and Microphone Amplification (Gain) The HL 5000 is equipped with separate controls for volume and gain to accommodate different user preferences across a variety of leak detection situations. 3.3.1 Setting the volume The user can set the headphone volume by using the two soft keys on the far right of the front panel (see Fig. -
Page 15: Setting The Gain
3.3.2 Setting the gain The amplification of the microphone signal, or gain, adjusts the level of sound passed from the microphone to the receiver for processing. A high gain setting would allow the equipment to detect and process far-off and/or low-level sounds more easily;... -
Page 16: The Main Screen
The Main Screen When performing leak detection, one of the difficulties faced by operators is how to identify and measure the sound made by a leak when other interfering sounds are also present. The HL 5000 utilizes a feature called Dual Segment Analysis (DSA) to differentiate between the two types of sounds. -
Page 17: Filter Settiing (Hl 5000 Professional)
Filter Setting (HL 5000 Professional) 3.5.1 What are filters? One of the characteristics of a sound is its frequency. Technically speaking, the frequency of a sound is the number of waves generated by that sound per cycle. The greater the number of waves per cycle, the higher the frequency of the sound. - Page 18 1. On the Filter Selection screen, a horizontal bar will be displayed beneath the selected filter or filters (Figure 12). When the unit is placed in normal Listening Mode (the Main Screen), Memory, or Continuous Listening Modes, the HL 5000 will focus on measuring the constant, minimum leak sound levels of only the frequencies selected by the user on the Filter Selection screen.

Page 20: Filter Selection In The Field
After the filters have been selected, use the ESC soft key to return to the main menu. Filter selection in the field Filter selection on the HL 5000 is largely determined by the type of pipe material the suspected leak is on and whether the operator is pre-locating or pinpointing the leak. -
Page 21: Mute Button
according to the above guidelines. It is possible, however, for leak sounds to be outside of the expected filter settings so a more systematic, 2-stage process is recommended: 1. Select all available filters and survey the system for any leak sound. When potential leak sound is detected, continue pre-location with all filters active until the loudest area of sound is located. -
Page 22: The Memory Mode
The Memory Mode The Memory Mode function is used to compare a series of sequentially recorded measurements and can be used for pre- locating or pinpointing leaks. To activate the memory mode function, press the memory soft on the control panel (Fig. 1). The LCD display simultaneously switches to the memory mode screen and the first memory measurement is activated. - Page 23 To exit the memory mode, press the ESC soft key. Continuous Measurement (HL5000 Professional) Continuous Measurement mode allows the operator to set the microphone in position and monitor sound levels at that location over short periods of time. Operators often use this feature to see what happens to a leak sound when a nearby valve is closed and re-opened.
- Page 24 Pressing the ESC soft key will exit the continuous measurement mode and return the user to the main screen. 3.10 Pipe Location Using the RSP-3 (HL5000 Professional) Most of today s technology for locating non-metallic water lines involves creating sound impulses on the water line itself and then tracing the line by hearing those sounds with an acoustic listening device like the HL 5000 .

Page 25: Switching Off The Hl5000
To enter Pipe Location Mode, press the impulse image soft key (second soft key from left) while the Welcome Screen is still displayed. When in Line Location Mode, the impulse image will be visible in the top left corner of the Main Screen and the measured sound level will be displayed by a single, wide bar. -
