SDT Ultrasound Solutions Compressed Air Leak Detector

Product Information

The LEAKChecker, LUBEChecker, TRAPChecker, and TIGHTChecker are ultrasound solutions that allow for easy detection and measurement of leaks, lubrication levels, traps, and tightness in various equipment and machinery.

• The device has a streaming screen that displays live RMS values with a brief history of RMS values.
• The device has gain management that indicates if the amplification is too high, too low, or correct.
• The device has a battery compartment that requires two AA alkaline or rechargeable batteries and can also be powered through its USB port with an external battery pack.
• The device has a sensor cable that needs to be correctly connected to the device and the sensor.
• The device requires amplification adjustment for every reading to ensure accurate measurement.
• The device automatically turns off when the battery power is insufficient or after 10 minutes of inactivity.
• The device can be updated through firmware using the SDT Updater software available on the manufacturer’s website.

Product Usage Instructions

1. Open the battery compartment using the supplied screwdriver and insert two AA alkaline or rechargeable batteries. Ensure that the remaining battery level is displayed in the right-hand top corner. A full green battery means that the battery is fully charged and has an autonomy of around 7 hours.
2. If necessary, connect the cable of the sensor to the device by lining up the red dot on the plug with the red mark on the connector and then inserting the plug into the connector. To unplug, move up the knurled barrel of the plug without any rotating movement.
3. To switch on the device, press the ON/OFF button once. To switch off, press the ON/OFF button for approximately 2 seconds.
4. For every reading, adjust the amplification using the up and down arrows and following the triangular amplification guidance icons in the top left-hand corner of the display. The current amplification setting is displayed here. Adjust the amplification until the reading (measurement) is displayed in green, and a smiley” appears in the left-hand top corner.
5. When the reading (measurement) is displayed in red, the amplification is too high and will need to be reduced by pressing the arrow down button. When ’-.-’ is displayed on the default screen or in orange in the streaming mode, the amplification is too low and will require increasing by pressing the arrow up button. In both cases, adjust the amplification until the reading (measurement) is displayed in green, and a smiley” appears in the left-hand top corner.
6. To switch between the default screen and the streaming screen, press the ON/OFF button once.
7. To update the firmware of your Checker, download the SDT Updater software on our website and install it using the provided USB cable.

PRODUCT OVERVIEW

Streaming screen

Powering your equipment

• Open up the battery compartment using the supplied screwdriver. Correctly insert two AA alkaline or rechargeable batteries. The remaining battery level is displayed in the right-hand top corner 1. A full green battery in the right-hand top corner means that the battery is fully charged. The equip-ment’s autonomy when fully charged will be around 7 hours.
• The device can be powered through its USB port  2 with an external battery pack.
• Important: The Checker turns off automatically when the battery power is insufficient to ensure proper operation, or after 10 minutes of inactivity.

Connecting the sensor cable

• If necessary, connect the cable of the sensor to the device by lining up the red dot on the plug with the red mark on the connector  9 and then inserting the plug into the connector.
• To unplug them, move-up the knurled barrel of the plug without any rotating movement. Proceed in the same way to connect and unplug the cable on the side of the flexible extension.
• The and “Sensor ?“ messages 10 indicate that no or an incompatible sensor is connected. The “x”- “sensor” indication will only disappear when the Checker is correctly wired up and connected to the correct sensor.

Using the Checker

• When pressing the on/off switch 4 , the equipment will switch on immediately.

• To switch off, the on/off button needs to be pressed for approx. 2 seconds.

• To take a correct measurement, the amplification needs to be adjusted for every reading in the default screen. This is done by using the up and down arrows  5 and following the triangular amplification guidance icons 5 in the top left-hand corner of the display.

• The current amplification setting is displayed here 7.

• Once the correct amplification level is reached, the reading (measurement) will be displayed in green and a “smiley” will appear in the place where previously the triangular amplification guidance icon was shown.

• When the reading (measurement) is displayed in red, the amplification is too high and will need to be reduced by pressing the “arrow down” button.

• When ‘’-.-‘’ is displayed on the default screen or in orange in the streaming mode, the amplification is too low and will require increasing by pressing the “arrow up” button. In both cases, i.e. when the amplification is too low or too high, the amplification should be adjusted until the reading
  (measurement) is displayed in green and the smiley” appears in the left hand top corner.

• To switch between the default screen and the streaming screen press the on/off button  4 once. A histogram giving a brief history of the measurement is dynamically displayed. The amplification adjustment is not available anymore.

• To update the firmware of your Checker, download the SDT Updater software on our website and install it using the provided USB cable.

Using the headphones

• To enhance the hearing experience, the audio volume of the headset can be adjusted by pressing the left and right arrows  5 until the sound level is comfortable.
• Avoid setting the sound too low as otherwise some signals may not be heard and possible leaky spots overlooked. Connect the headphones here 3. Set the volume to a safe level to protect yourself from permanent hearing loss. The current volume setting is displayed  8 only when a headset is connected.
