1. Introduction
This manual provides detailed instructions for the safe and effective use of your HABOTEST ZMF Type Digital Display Push-pull Force Meter. This precision instrument is designed for measuring push and pull forces, tension, spring force, and pressure in various applications. Please read this manual thoroughly before operation and keep it for future reference.
2. Product Overview
The ZMF series force meter features a digital display for clear readings and offers multiple measurement units and modes. It is a compact and ergonomic device suitable for a wide range of industrial and laboratory applications.
2.1 Key Components and Button Functions
- Connector: Top part for attaching various measurement accessories.
- LCD Display: Large screen for clear digital readings.
- SET (Menu Key): Used to access and adjust settings.
- PEAK (Mode Key): Toggles between different measurement modes (Real-time, Peak, First Peak).
- ZERO (Clear Key): Resets the current reading to zero.
- Power Key: Turns the device ON/OFF.
- UNIT (Unit Key): Cycles through available measurement units (N, kg, lb, Oz).
3. Setup
- Unpacking: Carefully remove the force meter and all accessories from its anti-drop plastic packaging.
- Battery Installation: Ensure batteries are installed correctly. The device does not include batteries.
- Attaching Accessories: Select the appropriate measurement attachment (e.g., hook, flat head, cone head) for your application. Screw it securely onto the connector at the top of the force meter.
- Power On: Press the Power Key to turn on the device.
- Zero Calibration: Before taking any measurements, ensure the display reads "0.0". If not, press the ZERO key to calibrate.
4. Operating Instructions
4.1 Measurement Modes
The ZMF force meter supports three distinct measurement modes:
- Real-time Mode: The display shows the current force being applied. No "P" or "T" indicators are visible on the screen.
- Peak Mode: Indicated by a "P" on the display. This mode records and holds the maximum force value detected during a measurement period.
- First Peak Mode: Indicated by both "P" and "T" on the display. This mode records and holds the first significant peak force detected within a measurement period.
Press the PEAK button to cycle through these modes.
4.2 Unit Conversion
The device allows for easy conversion between four common force units:
- N (Newtons)
- kg (Kilograms)
- lb (Pounds)
- Oz (Ounces)
Press the UNIT button to switch between these units. Approximate conversions are: 1kg ≈ 9.8N ≈ 2.204lb ≈ 35.2740oz.
4.3 Setting Alarms
The force meter can be configured to sound an alarm when measured force exceeds or falls below a preset threshold.
Use the SET button to enter the alarm setting menu. Follow the on-screen prompts to set your desired upper and lower force limits. The device will emit a buzzer sound if the measured force goes beyond these limits.
5. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the force meter in its original anti-drop plastic packaging in a dry, cool place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display to ensure accurate readings and prevent damage from battery leakage.
- Calibration: For professional applications requiring high accuracy, periodic calibration by a certified laboratory is recommended.
6. Troubleshooting
- Device does not power on:
- Check if batteries are installed correctly.
- Replace with new batteries.
- Inaccurate readings:
- Ensure the device is zero-calibrated before measurement. Press the ZERO key.
- Verify that the correct unit is selected.
- Check if the attachment is securely fastened.
- Consider professional calibration if issues persist.
- Display is blank or flickering:
- Check battery level and replace if low.
- Ensure the device is not exposed to extreme temperatures.

8. User Tips
While no specific user reviews or Q&A were provided, general tips for using force meters include:
- Always perform a zero calibration before each measurement session.
- Ensure the force is applied smoothly and consistently to avoid sudden spikes that might affect accuracy, especially in real-time mode.
- For peak measurements, apply force until the desired event occurs, then release and read the held peak value.
- Keep the device clean and free from dust or debris, which can affect button functionality and display clarity.
