6. Operating Instructions
6.1. Power On/Off
Press and hold the red Power button to turn the device on or off.
6.2. Unit Selection
With the device powered on, press the UNIT button repeatedly to cycle through the available measurement units: Newtons (N), Kilograms (kg), Pounds (Lb), and Ounces (Oz).
6.3. Zeroing the Display
Before taking a measurement, ensure no force is applied to the sensor. Press the ZERO button to reset the display to 0.00. This compensates for any minor offsets.
6.4. Taking a Measurement
Apply the force to be measured to the attached probe. The current force will be displayed on the screen.
For push measurements, apply force directly onto the probe. For pull measurements, use the hook attachment.
6.5. Peak Hold Function
Press the PEAK button to activate peak hold mode. The display will show the maximum force recorded during the measurement cycle. Press PEAK again to exit this mode and return to real-time measurement.
7. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in its protective carrying case in a dry, cool environment when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display.
- Calibration: Regular calibration by a qualified technician is recommended to maintain accuracy, especially for critical applications.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries | Check battery polarity; replace batteries |
| Inaccurate readings | Device not zeroed; sensor overload; need for calibration | Press ZERO button; ensure force is within range; consider professional calibration |
| Display shows "OL" | Overload | Remove applied force immediately; ensure measurement is within device's maximum capacity |
