4. Getting Started
4.1 Battery Installation
The force gauge requires two AAA batteries for operation. Batteries are not included in the package.
- Locate the battery compartment cover on the back of the device.
- Slide the cover downwards to open the compartment.
- Insert two AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Slide the battery compartment cover back into place until it clicks securely.

4.2 Attaching Measurement Accessories
Select the appropriate attachment (e.g., hook, flat head) for your specific measurement task. Screw the chosen attachment firmly onto the threaded shaft at the top of the force gauge.
5. Basic Operation
5.1 Power On/Off
- To power on the device, press the POWER button (red button with power symbol).
- To power off the device, press and hold the POWER button for a few seconds until the display turns off.
5.2 Zeroing the Display
Before taking a measurement, it is crucial to zero the display to ensure accuracy.
- Ensure no force is being applied to the gauge.
- Press the ZERO button. The display should show "0.0" or "0.00" depending on the selected unit.
5.3 Unit Conversion
The force gauge supports four measurement units: Newtons (N), Pounds (Lb), Kilograms (Kg), and Ounces (Oz).
- Press the UNIT button to cycle through the available units. The current unit will be displayed on the LCD screen.

6. Measurement Modes
The device offers three distinct measurement modes to suit different testing requirements.
- Press the PEAK button to cycle through the modes.

6.1 Real-time Mode
In Real-time Mode, the display shows the current force being applied to the gauge. This mode is suitable for continuous monitoring of force changes.
6.2 PEAK Mode
In PEAK Mode, the gauge records and holds the maximum force value detected during the measurement period. This is useful for capturing the highest force applied in a test.
6.3 First-PEAK Mode
First-PEAK Mode captures and holds the first peak force detected. This mode is often used in applications where the initial maximum force is critical, such as break-away force or initial insertion force.
7. Advanced Settings
7.1 Auto Power Off
The device features an auto power-off function to conserve battery life. It will automatically shut down after a period of inactivity.
- The auto shutdown time can be set between 0 and 15 minutes.
- The default auto power-off time is 10 minutes.
- Refer to the full user manual for instructions on how to adjust this setting.
7.2 Minimum Force Shielding
The dynamometer can be configured to shield (not display) data below 0.5% of its full scale capacity. This helps to filter out minor fluctuations or noise in measurements.
- This function is enabled by default.
- It can be cancelled if desired, allowing the display of very small force values.
- Consult the comprehensive user manual for details on disabling this feature.
8. Performing Measurements
The Mxmoonfree ZMF-50N is designed for both push and pull force testing.

8.1 Push Test
- Attach a suitable flat or conical head to the gauge.
- Ensure the display is zeroed.
- Apply force by pushing the gauge against the object or surface to be measured.
- Read the force value on the display. If in PEAK mode, the maximum force will be held.
8.2 Pull Test
- Attach the hook accessory to the gauge.
- Ensure the display is zeroed.
- Hook the gauge onto the object to be measured and apply a pulling force.
- Read the force value on the display. If in PEAK mode, the maximum force will be held.
9. Care and Maintenance
9.1 General Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or display.
9.2 Battery Replacement
When the battery indicator on the LCD shows low power, replace both AAA batteries promptly to ensure accurate readings and continuous operation. Refer to Section 4.1 for battery installation instructions.
9.3 Storage
When not in use, store the force gauge and its accessories in the provided protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
10. Troubleshooting
10.1 Device Does Not Power On
- Check if the batteries are inserted correctly with the proper polarity.
- Replace old or depleted batteries with new AAA batteries.
10.2 Inaccurate Readings
- Ensure the display is zeroed before each measurement.
- Verify that the correct measurement unit is selected.
- Avoid applying force unevenly or at an angle.
- Ensure the attachment is securely fastened.
10.3 Display is Dim or Flickering
- This usually indicates low battery power. Replace the batteries.
