How do I calibrate the Lafayette Hydraulic Pinch Gauge before each use?

[Murphy]

To ensure accurate measurements with your Lafayette Hydraulic Pinch Gauge, it's essential to calibrate it before each test. Here's how: 1. Hold the rounded end of the gauge, ensuring you support its weight, with the pressure pad facing the patient. 2. Rotate the center dial counter-clockwise until the peak hold needle aligns with zero. This step is critical for establishing a correct baseline. 3. While maintaining your grip, have the patient apply pressure to the pinch block and pressure pad using the thumb and finger being assessed. Calibrating the gauge before each trial sets a reliable reference point, minimizing potential errors and guaranteeing consistent, dependable results in your strength measurements.
