3.1. Components
- Spherical Measurement Probe: Used for non-destructive contact with the material surface.
- LCD Display: Shows moisture readings, MIN/MAX values, and function indicators.
- Power Button: Turns the device on and off.
- Function Buttons: (e.g., MIN/MAX, HOLD) for specific measurement modes.
- Battery Compartment: Located at the rear of the device.
3.2. Display Indicators
- Main Reading: Displays the current moisture value.
- MIN: Shows the minimum moisture value recorded during a measurement session.
- MAX: Shows the maximum moisture value recorded during a measurement session.
- HOLD: Indicates that the current reading is frozen on the display.
- DRY: May indicate a low moisture level or a specific measurement mode.
- Battery Indicator: Shows remaining battery life.
4. Setup
4.1. Battery Installation
The VOLTCRAFT MF-100 requires 3 AAA batteries for operation.
- Locate the battery compartment cover on the rear of the device.
- Slide or unclip the cover to open the compartment.
- Insert 3 AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Replace the battery compartment cover securely.
Note: Always use fresh batteries and remove them if the device will not be used for an extended period to prevent leakage.
5. Operating Instructions
5.1. Powering On/Off
- To turn on the device, press the Power button (usually marked with ⑂). The display will illuminate and show an initial reading, often 0.0 in air.
- To turn off the device, press and hold the Power button for a few seconds until the display turns off. The device may also have an auto-off function to conserve battery.
5.2. Performing a Non-Destructive Measurement
The MF-100 uses a non-destructive method, meaning it does not require piercing the material.
- Ensure the device is powered on.
- Place the spherical measurement probe flat against the surface of the material you wish to measure. Ensure full contact between the probe and the surface.
- The display will show the current moisture reading. Move the device slowly across the surface to identify areas with varying moisture levels.
- The reading represents the relative moisture content of the material. Refer to material-specific guidelines or experience for interpretation.
This image displays the VOLTCRAFT MF-100 showing a "0.0" reading, indicating a very low or no moisture content, typically seen when the device is in the air or on a completely dry surface.
The VOLTCRAFT MF-100 is shown displaying a numerical moisture reading (e.g., 14.5), along with MIN and MAX values, indicating an active measurement of moisture in a material.
5.3. Using MIN/MAX Function
The MIN/MAX function allows you to track the lowest and highest moisture values detected during a continuous measurement session.
- While measuring, the device automatically updates the MIN and MAX values on the display.
- This is particularly useful when scanning large areas or when the display is not easily visible during the measurement process.
- The device may feature an acoustic alarm that activates when a predefined moisture threshold (often related to MAX) is exceeded. Consult the device's specific button layout for activating/deactivating this feature if available.
5.4. Using the HOLD Function
The HOLD function freezes the current measurement reading on the display, allowing you to record or analyze it without the value changing.
- During a measurement, press the HOLD button (if present, or a multi-function button). The "HOLD" indicator will appear on the display.
- The displayed value will remain fixed until you press the HOLD button again to release it, or until the device automatically exits HOLD mode.
6. Maintenance and Care
- Cleaning: Wipe the device exterior with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure accurate readings.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Dead or incorrectly inserted batteries. | Check battery polarity. Replace with new AAA batteries. |
| Inaccurate or fluctuating readings. | Poor contact with surface; device not calibrated; extreme environmental conditions. | Ensure full contact of the probe. Allow device to stabilize in new environment. If issues persist, contact support. |
| Display shows "HOLD" and doesn't update. | HOLD function is active. | Press the HOLD button again to deactivate the function. |
| Acoustic alarm sounds frequently. | High moisture detected; alarm threshold set too low. | Investigate the measured area for high moisture. Adjust alarm settings if possible (refer to specific device instructions). |
