5. Setup
5.1 Initial Charging
Before first use, fully charge the device. Connect the provided USB cable to the gauge and a suitable USB power source (e.g., computer USB port or wall adapter). The charging time is typically 4-6 hours.
5.2 Power On/Off
Press and hold the Power button () to turn the device ON or OFF.
5.3 Attaching Accessories
Select the appropriate L-shaped rod, clamps, or extension rods for your specific testing application. Securely attach them to the force sensor at the bottom of the gauge.
6. Operating Instructions
6.1 Unit Selection
Press the Unit button (U) to cycle through the available measurement units: Newtons (N), Kilograms (kg), and Pounds (lb).
6.2 Test Modes
The GF500D supports three test modes, which can be switched using the Mode button (M).
- LIVE Mode (Real-time): Displays force data in real-time. The device automatically resets to zero after each measurement.
- PEAK Mode: Measures and holds the maximum force value detected. Press the Clear button (C) to clear the peak value.
- AUTO PEAK Mode: Displays the peak value for 2 seconds, then automatically returns to zero.
