4.2. Attaching Accessories
Select the appropriate accessory (e.g., hook, flat head) for your specific testing requirement. Screw it firmly onto the threaded shaft at the top or bottom of the force gauge.
5. Operating Instructions
5.1. Power On/Off
Press the POWER button (red button in the center) to turn the device on or off.
5.2. Unit Conversion
The force gauge supports four measurement units: Newtons (N), Pounds (Lb), Kilograms (Kg), and Ounces (Oz). To switch between units, press the UNIT button (green button on the right).

5.3. Measurement Modes
The device features three measurement modes: Real-time, Peak, and First Peak. Press the PEAK button (blue button on the left) to cycle through these modes.
- Real-time Mode: The display shows the current force being applied. The value changes dynamically with the load.
- Peak Mode: The display holds the maximum force value recorded during the measurement. This is useful for destructive testing or capturing peak loads.
- First Peak Mode: The display shows the first peak force value measured within a period of time. This is indicated by 'P' and 'T' on the screen.

5.4. Zeroing the Display
Before taking a measurement, ensure the display reads 0.0. If not, press the ZERO button (green button on the right, above UNIT) to reset the reading.
5.5. Performing a Test
Attach the appropriate accessory. Apply force to the object being tested. The display will show the force value according to the selected measurement mode.
