3. Initial Setup

3.1. Battery Installation

1. Locate the battery compartment cover on the back of the device.
2. Open the cover and insert two AAA batteries, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

3.2. Attaching Measurement Adapters

The force gauge comes with various adapters for different testing scenarios. To attach an adapter:

1. Select the appropriate adapter for your measurement task (e.g., hook for tension, flat head for compression).
2. Screw the adapter firmly into the measurement axis at the top of the device. Ensure it is securely fastened to prevent inaccurate readings or detachment during use.

4. Operating Instructions

4.1. Power On/Off

• To power on the device, press the POWER button.
• To power off the device, press and hold the POWER button for a few seconds until the display turns off.

4.2. Selecting Measurement Modes

The device supports three measurement modes: Real-time, Peak, and First Peak. Press the PEAK button to cycle through these modes.

• Real-time Mode (Tracking): Displays the current force being applied.
• Peak Mode (P): Captures and displays the maximum force detected during a measurement cycle.
• First Peak Mode (PT): Captures and displays the first significant peak force detected.

4.3. Unit Conversion

The device can display measurements in Newton (N), kilogram (kg), pound (lb), and ounce (oz). Press the UNIT button to switch between these units.

4.4. Setting Upper and Lower Limits

You can set upper and lower force limits for quality control or specific testing requirements. When the measured force exceeds these limits, an audible alarm will sound.

1. In Peak (P) or First Peak (PT) mode, press the SET button to enter the limit setting menu.
2. Use the PEAK and UNIT buttons to adjust the values for the upper and lower limits.
3. Press SET again to confirm and exit.

5. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the force gauge in its original packing box in a dry, cool place away from direct sunlight and extreme temperatures. Remove batteries if the device will not be used for an extended period.
• Calibration: Regular calibration is recommended to maintain measurement accuracy, especially for professional applications. Consult a certified calibration laboratory if required.

6. Troubleshooting

• Device does not power on: Check battery installation and ensure batteries are not depleted. Replace with new AAA batteries if necessary.
• Inaccurate readings: Ensure the measurement adapter is securely attached. Verify that the correct unit is selected. Consider recalibration if persistent inaccuracies occur.
• Display is upside down during tension tests: The display orientation is fixed. For tension tests where the device is inverted, use the Peak mode to capture the maximum value, then read the result after the test is complete.
• Audible alarm not working: Check the alarm settings in the device menu to ensure it is enabled and limits are correctly configured.
