REED Instruments TM-8811-NIST Ultrasonic Thickness Gauge with probes and a calibration certificate.

شڪل 1: REED Instruments TM-8811-NIST Ultrasonic Thickness Gauge and a sample calibration certificate.

This image displays the REED Instruments TM-8811-NIST Ultrasonic Thickness Gauge, a blue handheld device with a digital display showing "0.000". Two probes are connected to the top of the device via cables. Below the display are several control buttons: a red power button (circle with a vertical line), "SELECT", "CAL", "VEL", "mm/inch", and up/down arrow buttons. The text "Ultrasonic Thickness Gauge" and "COUPLING" are visible on the device face. Partially visible in the background is a "CALIBRATION CERTIFICATE" document, indicating the importance of calibration for such instruments.

اهم اجزاء:

4. سيٽ اپ

  1. بيٽري لڳائڻ: Open the battery compartment (typically on the back) and insert the required batteries, observing correct polarity. Close the compartment securely.
  2. تحقيق ڪنيڪشن: Connect the ultrasonic probe(s) to the connectors at the top of the gauge. Ensure a firm connection.
  3. پاور آن: کي دٻايو Power button to turn on the device. The display will illuminate.

5. آپريٽنگ هدايتون

5.1 بنيادي ماپ

  1. مٿاڇري تيار ڪريو: Ensure the surface of the material to be measured is clean, smooth, and free of rust, paint, or debris.
  2. Apply Couplant: Apply a small amount of ultrasonic couplant (e.g., glycerin, gel) to the surface where the measurement will be taken. This ensures proper sound transmission.
  3. Place Probe: Press the probe firmly and flatly against the prepared surface. The "COUPLING" indicator on the display should appear, confirming good contact.
  4. ماپ پڙهو: The thickness reading will be displayed on the LCD. If the reading is unstable, adjust the probe position or reapply couplant.
  5. جاچ هٽايو: Lift the probe from the surface. The reading will typically hold or return to zero.

5.2 Unit Selection (mm/inch)

کي دٻايو ايم ايم / انچ button to toggle between millimeters (mm) and inches (inch) for the displayed thickness measurement.

5.3 Sound Velocity Adjustment

The accuracy of ultrasonic thickness measurement depends on the correct sound velocity setting for the material being tested. Refer to a material velocity chart for common materials.

  1. کي دٻايو VEL button. The current sound velocity value will be displayed.
  2. استعمال ڪريو Up ۽ هيٺ arrow buttons to adjust the velocity to the desired value for your material.
  3. دٻايو VEL ٻيهر يا چونڊيو to confirm and exit velocity adjustment mode.

6. حساب ڪتاب

The TM-8811-NIST gauge is factory calibrated. However, periodic calibration checks and adjustments are crucial for maintaining measurement accuracy, especially when measuring different materials or after prolonged use. The device may feature a built-in calibration block or require external reference standards.

6.1 صفر حساب ڪتاب

Zero calibration compensates for the probe delay line. This is typically performed by placing the probe on a known thickness standard or by coupling the probe to itself (if applicable to the probe type).

  1. Ensure the probe is clean and free of couplant.
  2. کي دٻايو CAL بٽڻ. اسڪرين تي ڏنل هدايتن تي عمل ڪريو.
  3. Place the probe on the zero calibration block or perform the specified zeroing procedure.
  4. calibration جي تصديق ڪريو.

6.2 ٻه نقطي حساب ڪتاب

For enhanced accuracy, especially over a range of thicknesses, a two-point calibration using two known thickness standards (e.g., thin and thick) is recommended.

  1. کي دٻايو CAL button and select the two-point calibration option.
  2. Measure the first known thickness standard and input its value using the arrow buttons.
  3. Measure the second known thickness standard and input its value.
  4. calibration جي تصديق ڪريو.

Always refer to the specific instructions in the device's internal menu for detailed calibration procedures.
