Video 1: Demonstration of how to connect the probe to the TM5120B Gaussmeter unit. Ensure the probe is aligned with the slot and inserted directly.

To begin using the Gaussmeter, first ensure the device is powered off. Carefully align the connector of the desired Hall probe (either axial or radial) with the corresponding slot on the main unit. Gently push the connector directly into the slot until it is securely seated. Avoid forcing the connection to prevent damage to the pins.

Funktionstast overview

Video 2: Detailed explanation of the various function keys on the TM5120B Gaussmeter, including DC/AC mode switching, HOLD function, REL (relative measurement), backlight control, and unit switching.

The TM5120B Gaussmeter features an intuitive button layout for easy operation. Below is a guide to its primary function keys:

• DC/AC Key: Toggles between Direct Current (DC) and Alternating Current (AC) magnetic field measurement modes.
• HOLD-tast: Pressing this key automatically saves and displays the maximum magnetic field value measured. Press again to cancel the hold function and resume live readings.
• REL (Relative) Key: This button allows you to set the current magnetic field strength at the probe's location to zero. This is useful for measuring relative changes in magnetic fields. Press again to cancel the magnetic field zero state setting.
• Confirmation Button / Backlight Key: Press this key to turn on the display backlight for improved visibility in low-light conditions. Pressing it again will turn off the backlight.
• Right Click / Unit Switching Key: Use this key to cycle through different measurement units: milliTesla (mT), Gauss (G), Oersted (Oe), and kiloAmpere per meter (kA/m).
• Cross-key Area (Up, Down, Left, Right): These directional buttons, in conjunction with the central confirmation button, enable advanced functions such as setting maximum/minimum alarms and configuring automatic shutdown. Refer to the full user manual for detailed operation of these advanced settings.

At udføre en Sample Test

Video 3: Demonstration of how to perform a sample test using the TM5120B Gaussmeter, including preparing the probe and using the HOLD function to capture maximum values.

To measure a magnetic field:

1. Forbered sonden: Gently rotate the probe cover to open it and expose the Hall sensor.
2. Placer sonden: Use the "TEST" surface of the probe to position it as close as possible to the magnetic field source or test sample.
3. Measure and Hold: While measuring, you can use the HOLD key function to capture and display the maximum magnetic field value detected on the sample surface. The AC magnetic field detection method is consistent with DC magnetic field operation.

Opretholdelse

To ensure the longevity and accuracy of your HFBTE AC DC Magnetometer, follow these maintenance guidelines:

• Rensning: Use a soft, dry cloth to clean the main unit and probes. Do not use abrasive cleaners or solvents, as they may damage the device.
• Opbevaring: When not in use, store the Gaussmeter and its probes in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the probe covers are in place to protect the sensitive Hall sensors.
• Udskiftning af batteri: If the battery remaining power display indicates low power, replace the 3 AA batteries promptly to maintain optimal performance.
• Probepleje: Handle the Hall probes with care. Avoid bending or subjecting them to excessive force, as this can damage the internal sensor.
• Kalibrering: Regular calibration is recommended to ensure measurement accuracy, especially after prolonged use or if accuracy is critical for your application. Refer to the full user manual for information on calibration procedures or contact customer support.
