The REED Instruments TM-8811-NIST is an ultrasonic thickness gauge designed for quick and accurate measurements. It features a large LCD display and intuitive controls.

Setšoantšo sa 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.

5.1 Tekanyo ea Motheo

1. Lokisa Sebaka: 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. Bala Tekanyo: The thickness reading will be displayed on the LCD. If the reading is unstable, adjust the probe position or reapply couplant.
5. Remove Probe: Lift the probe from the surface. The reading will typically hold or return to zero.

5.2 Unit Selection (mm/inch)

Tobetsa ea mm/inch 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. Tobetsa ea VELELA button. The current sound velocity value will be displayed.
2. Sebelisa le Up le Tlase arrow buttons to adjust the velocity to the desired value for your material.
3. Tobetsa VELELA hape kapa KHETHA to confirm and exit velocity adjustment mode.

6. Calibration

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 Zero Calibration

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. Tobetsa ea KALA button. Follow the on-screen prompts.
3. Place the probe on the zero calibration block or perform the specified zeroing procedure.
4. Netefatsa tekanyo.

6.2 Tekanyetso ea Lintlha tse peli

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. Tobetsa ea KALA 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. Netefatsa tekanyo.

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

7. Tlhokomelo

• Ho hloekisa: Wipe the instrument and probes with a soft, dry cloth after each use. Do not use abrasive cleaners or solvents.
• Polokelo: Store the gauge in its protective case in a cool, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
• Phetoho ea Betri: Tlosa libetri ha letšoao la betri le tlase le hlaha skrineng.
• Tlhokomelo ea Probe: Inspect probes regularly for wear or damage. Replace damaged probes to ensure accurate measurements.
