The internal calibration process for the Lamy Rheology FIRST PLUS LR involves the following steps:

1. Install the Spindle: Refer to section 3.1 and install spindle L2.
2. Select Spindle and Speed: Go to section 2.2.2, select spindle L2, and set the speed to 60 rpm.
3. Zero Adjustment: Perform a zero adjustment.
4. Immerse the Spindle: Follow section 3.2 to immerse the spindle in the standard oil at the correct level (marked on the spindle).
5. Wait for Temperature Stabilization: Allow 15 minutes for the standard oil to reach the correct temperature.
6. Set Measurement Parameters: Select a measuring time of 60 seconds and start the measurement at 60 rpm.
7. Check the Result: The result should be within ±5% of the standard viscosity value.
8. Troubleshooting: If the measurement is out of range, check for errors such as incorrect filling, zero adjustment, spindle rotation, or temperature settings. If necessary, recalibrate the instrument.

This process ensures accurate and reliable viscosity measurements.

  • Page 3: Introduction

    1. INTRODUCTION The FIRST PLUS is a device able to measure the viscosity, which is the capacity of a product to resist to the flow. The fluid is forced to a shear rate (rotational speed) and the shear stress (motor torque) is measured.
