5. Operating Instructions
5.1 Power On/Off
- Press the OFF/ON button to power on the device. The measurement interface will appear.
- Press the OFF/ON button again to power off the device.
5.2 Zero Function
- With no load applied, press the ZERO button to reset the current reading on the screen to zero.
5.3 Unit Conversion
- Press the UNIT button to cycle through the available measurement units: Newtons (N), Kilograms (Kg), and Pounds (Lb).
5.4 Peak Hold Mode
- From the measurement interface, press the SET button to enter "Peak Hold" mode. In this mode, the instrument records and displays the maximum force value measured during a testing period.
5.5 Setting Parameters
To access the setting menu:
- With the device powered on, press and hold the SET button for 4-5 seconds, then release. The display will show "HIDT" (High Limit Setting).
- Continuously press the UNIT button to cycle through other settings: "LODT" (Low Limit Setting), "L.SET" (Minimum Peak Value Save), "OFFT" (Auto-off Time), "G.SET" (Gravity Acceleration), "BAC.S" (Backlight Setting), and "R.SET" (Restore Factory Settings).
5.5.1 HIDT (High Limit Setting)
Sets the upper limit for the test value. The default is 99% of the full range. If the measured value exceeds this limit, the instrument will alarm. Use UNIT and ZERO buttons to adjust the value. Press SET to save and return to the setting menu.
5.5.2 LODT (Low Limit Setting)
Sets the lower limit for the test value. The default is 0. If the measured value falls below this limit, the instrument will alarm. Adjust and save similarly to HIDT.
5.5.3 L.SET (Minimum Peak Value Save)
In peak hold mode, if the current peak value is less than this set value, it will not be saved.
5.5.4 OFFT (Auto-off Time)
Set the automatic shutdown time from 1 to 9999 minutes, or set to "00" for no automatic shutdown. The default is 10 minutes. Press SET to confirm.
5.5.5 G.SET (Gravity Acceleration)
Users can set the gravity acceleration value according to their local region. The default value is 9.800.
5.5.6 BAC.S (Backlight Setting)
Use the UNIT button to select "YES" to enable backlight or "NO" to disable it. Press SET to save.
5.5.7 R.SET (Restore Factory Settings)
To restore the instrument to factory default settings, press the SET button when "R.SET" is displayed. The machine will shut down. Power it on again to use.
5.6 Basic Measurement Procedure
- Power on the device.
- Attach the appropriate test fixture.
- Hold the force gauge firmly or mount it on a suitable test stand.
- Apply the force to be measured, ensuring the force is applied in a straight line with the push-pull rod for accurate readings.
- Read the force value on the digital display.
- After testing, remove the load, power off the device, and detach the fixtures.
6. Maintenance
6.1 Cleaning
Clean the instrument with a soft cloth. If necessary, dampen the cloth with water and a mild detergent, wring it dry, and then wipe the instrument. Do not use volatile chemicals such as thinners or alcohol, as they may damage the surface.
6.2 Storage
Store the instrument within the specified temperature and humidity range to prevent malfunction. Keep all accessories clean and organized in their storage box for future use.
6.3 Battery Care
The device is powered by a 3.7V lithium battery. Ensure regular charging to maintain battery health. The instrument features low battery indication and various protections (short circuit, leakage, overload) to prolong battery life and ensure safe operation.
7. Troubleshooting
| Symptom | Cause | Solution |
|---|---|---|
| No display when powered on | Battery depleted | Recharge the battery |
| Inaccurate test values | Excessive error | Return to factory for calibration |
| Instrument freezes/crashes | No response to any button | Press the reset button with a pointed object |
| Overload alarm (beeping) | Measured value exceeds 100% of full range | Quickly remove or reduce the applied load. If it exceeds 120%, the instrument may be damaged. |
7.1 Resolving Instrument Freezing
If the instrument unexpectedly freezes, use a small, pointed object (like a pin) to press the reset button located on the side of the device. This will perform a hard reset and power off the unit. You can then power it on again.
