Murakami Tension Meter – Precision Tension Measurement for Screen Printing

Calibrating a Murakami Tension Meter using the glass calibration method is essential to ensure accurate tension measurements. The glass calibration method utilizes a known reference point to verify the tension meter’s accuracy. Follow these step-by-step instructions to calibrate your Murakami Tension Meter effectively:

Materials Needed:

• Murakami Tension Meter
• Glass calibration plate (or a piece of glass with a known tension value)
• Soft cloth or lint-free microfiber cloth

Calibration Steps:

1. Prepare the Tension Meter: Ensure that the Murakami Tension Meter is clean and free from any debris or dust. Use a soft cloth or lint-free microfiber cloth to gently wipe the meter’s surfaces, both the contact area and the scale.
2. Prepare the Glass Calibration Plate: If you have a glass calibration plate with a known tension value, make sure it is clean and free from any contaminants. If you don’t have a dedicated calibration plate, you can use a piece of glass with a known tension value. This value can be obtained from the manufacturer or a reputable calibration source.
3. Place the Glass Calibration Plate: Lay the glass calibration plate on a flat, stable surface. Ensure that the glass is free from any warping or damages that could affect the calibration process.
4. Zero the Tension Meter: Before proceeding with the calibration, zero the tension meter to account for any offset. To do this, gently press the tension meter onto the glass calibration plate, then set the meter’s needle to zero by adjusting the zero adjustment screw if needed.
5. Apply the Calibration Force: Now, apply the calibration force to the tension meter. This force should match the known tension value of the glass calibration plate. Ensure that the tension meter’s contact area is in full contact with the glass surface.
6. Read the Measurement: With the calibration force applied, read the measurement displayed on the tension meter’s scale. Compare this reading to the known tension value of the glass calibration plate.
7. Adjust the Calibration (if necessary): If the tension meter’s reading matches the known tension value, then the meter is accurately calibrated. If there is a discrepancy, you may need to adjust the tension meter accordingly. Many tension meters have a calibration screw or knob that can be adjusted to match the known tension value.
8. Repeat (if desired): For added accuracy, you can repeat the calibration process multiple times, taking multiple measurements and comparing them to the known tension value.
9. Record and Mark: Once the calibration is successfully completed, record the calibration value for future reference. You can also mark the tension meter or its case with the calibration value to easily identify the calibrated meter.

Regular calibration is crucial to maintain the accuracy of your Murakami Tension Meter. By following these instructions and calibrating your tension meter periodically, you can ensure consistent and reliable tension measurements, leading to high-quality screen prints with optimal tension control.
