Safety Information

While the calibration block is a passive device, general safety practices should always be observed when handling precision instruments and working in industrial environments.

• Always handle the calibration block with clean hands to prevent contamination of the surfaces.
• Store the block in its provided air-tight plastic storage box when not in use to protect it from dust, moisture, and physical damage.
• Avoid dropping or subjecting the block to impact, as this can alter its precise dimensions and affect calibration accuracy.
• Keep the block away from corrosive chemicals or extreme temperatures.

Product Components

Your SULMILE 8-Step Test Calibration Block package includes:

• One (1) SULMILE 8-Step Test Calibration Block (#1018 Steel)
• One (1) Air-Tight Plastic Storage Box

Setup and Preparation

The SULMILE 8-Step Test Calibration Block requires minimal setup. Its primary function is to provide known thickness values for calibrating ultrasonic thickness gauges.

1. Unpacking: Carefully remove the calibration block from its air-tight plastic storage box.
2. Inspection: Visually inspect the block for any signs of damage, corrosion, or surface imperfections that could affect its accuracy. Ensure all stepped surfaces are clean and free of debris.
3. Surface Preparation: Before use, ensure the surface of the calibration block and the transducer of your ultrasonic thickness gauge are clean. A thin layer of ultrasonic couplant is typically applied to the block's surface to ensure proper sound transmission.

Operating Instructions (Calibration Procedure)

This calibration block is designed to provide eight distinct thickness values for calibrating ultrasonic thickness gauges. The specific steps are 1.0'', 1.5'', 2.0'', 2.5'', 3.0'', 3.5'', 4.0'', and 4.5'' (inches).

1. Power On Gauge: Turn on your ultrasonic thickness gauge and allow it to warm up according to its manufacturer's instructions.
2. Select Calibration Mode: Navigate to the calibration mode on your ultrasonic thickness gauge.
3. Apply Couplant: Apply a small amount of ultrasonic couplant to the surface of the desired step on the calibration block.
4. Place Transducer: Firmly place the transducer of your ultrasonic thickness gauge onto the couplant-covered step. Ensure good contact and avoid air gaps.
5. Perform Calibration: Follow your gauge's specific instructions for performing a single-point or multi-point calibration using the known thickness values of the calibration block steps. For multi-point calibration, repeat steps 3 and 4 for several different steps on the block.
6. Verify Readings: After calibration, take readings on various steps of the block to verify the accuracy of your gauge. The readings should closely match the marked thickness values on the block.
7. Clean Up: After use, wipe off any remaining couplant from the calibration block and the transducer.

Maintenance and Storage

Proper maintenance and storage are crucial for preserving the accuracy and longevity of your calibration block.

• Cleaning: After each use, thoroughly clean the block with a soft, lint-free cloth to remove all traces of ultrasonic couplant. For stubborn residue, a mild, non-abrasive cleaner can be used, followed by a complete drying.
• Inspection: Periodically inspect the block for any signs of wear, scratches, or corrosion. Any damage to the measurement surfaces can compromise accuracy.
• Storage: Always store the calibration block in its provided air-tight plastic storage box. This protects it from dust, humidity, and physical damage. Store in a cool, dry environment, away from direct sunlight or extreme temperature fluctuations.
• Recalibration: While the block itself does not "wear out" in the traditional sense, its accuracy should be periodically verified against a higher-standard reference or by a certified metrology lab, especially if precise measurements are critical.

Troubleshooting

If you encounter issues during calibration, consider the following common troubleshooting steps:

• Inaccurate Readings:
  • Ensure sufficient couplant is used and there are no air bubbles between the transducer and the block.
  • Verify the transducer is making firm, flat contact with the block surface.
  • Check if the ultrasonic thickness gauge itself requires service or recalibration.
  • Inspect the calibration block for any physical damage or surface imperfections.
• No Reading:
  • Confirm the ultrasonic thickness gauge is powered on and functioning correctly.
  • Ensure proper application of couplant.
  • Check the transducer cable connection to the gauge.
