- Included Carrying Case: A fitted foam carrying case protects the instrument during transport and storage.
3. Setup
3.1 Unpacking
Carefully remove the dynamometer and its accessories from the protective carrying case. Inspect all components for any signs of damage. The package should include the dynamometer and a user manual.
Figure 2: The dynamometer and its components neatly arranged within the protective carrying case.
3.2 Battery Installation/Charging
The device requires 1 Lithium Ion battery, which is included. Ensure the battery is properly installed and charged before first use. Connect the provided charger to the device and a power source if the battery level is low. The color LCD display will indicate charging status.
3.3 Adjusting the Handle Position
The dynamometer features a 5-position adjustable handle to accommodate different hand sizes and grip preferences. To adjust, locate the adjustment mechanism (typically a pin or lever) near the handle. Select the desired position (1 through 5) that allows for a comfortable and secure grip for the user being tested.

4. Operating Instructions
4.1 Powering On/Off
- To power on, press the POWER button located on the display panel.
- To power off, press and hold the POWER button until the device shuts down.
4.2 Performing a Max Force Test (Functional Model)
The Functional model is designed for straightforward Max Force testing, displaying live, real-time strength readings.
- Ensure the device is powered on.
- Press the SELECT button to navigate to the Max Force Test protocol.
- If necessary, press the DELETE button to reset the current test to zero before starting a new measurement.
- Instruct the user to grip the dynamometer firmly and apply maximum force. The display will show live readings in both pounds (LBS) and kilograms (KG).
- The peak maximum value will be displayed until digitally reset.
- After the test, the device can calculate and display statistics such as Mean, Standard Deviation (SD), and Coefficient of Variation (COV).

4.3 Data Management
Test results are stored on the device. For detailed analysis or record-keeping, data can be transferred to a local PC. Refer to the device's on-screen menu or a separate software guide (if applicable) for instructions on data transfer. The device is also Bluetooth-enabled for future application connectivity.
5. Maintenance
The Baseline BIMS Digital Dynamometer is designed for low maintenance due to its digital load-cell technology and absence of hydraulic oil. Regular maintenance includes:
- Cleaning: Wipe the device with a soft, damp cloth. Avoid using abrasive cleaners or submerging the device in liquid.
- Storage: Store the dynamometer in its protective carrying case when not in use to prevent dust accumulation and physical damage. Store in a cool, dry place.
- Battery Care: Ensure the Lithium Ion battery is charged regularly, especially if the device will be stored for an extended period.
- Calibration: While the digital technology offers high accuracy, periodic calibration by a certified service provider is recommended to ensure continued precision, especially in professional settings.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the device using the provided charger. Ensure the charger is properly connected to a power source. |
| Inaccurate or inconsistent readings. | Device not zeroed before test; improper grip; need for calibration. | Press the DELETE button to zero the device before each test. Ensure the user has a consistent grip. Consider professional calibration if issues persist. |
| Display is blank or frozen. | Software error; low battery. | Attempt to restart the device by holding the POWER button. If unresponsive, connect to charger. If problem persists, contact customer support. |
| Cannot transfer data. | Incorrect connection; software issue. | Ensure proper connection to PC. Verify that any required software or drivers are installed. Consult the manufacturer's website for data transfer instructions or software updates. |
