Handheld Three-dimensional Gauss Meter
Introduction
Dexinmag has developed an ultra-small, ultra-wide operating temperature range, high linearity, high sensitivity, and wide measurement range Hall sensor for magnetic field measurement, achieving a maximum linearity of 0.01% and an active area size of 0.028mm. The device integrates a patented 3D probe orthogonal angle correction technology, controlling orthogonality deviation to within 0.1°. The device is equipped with professionally designed and optimized hardware circuitry to perfectly unleash the sensor's performance potential. The digital circuitry uses a high-performance ARM Cortex 32-bit microcontroller chip, featuring a high-performance, efficient memory architecture, faster response speed, and lower measurement latency. The analog circuitry employs the patented ULLASS ultra-low-loss sampling technology to achieve high-quality acquisition of weak signals. The ultra-high-definition large screen reproduces data details with exquisite colors, and its wide viewing angle is unaffected by strong light interference, ensuring clear visibility even in complex environments. The user-friendly interactive touch design makes operation smooth and convenient; a light touch allows for easy completion of various function settings and data retrieval, eliminating cumbersome buttons and providing a completely upgraded user experience. The product complies with international system certifications such as ISO9001, CE, and IQNET.

Function Introduction
|
|
|
|
|
Magnetic Field Measurement
Touch buttons include: zeroing, AC/DC switching, unit switching, range switching, data saving, maximum and minimum value display, screen hold, and menu. |
Menu Settings
The menu interface includes threshold settings, version information viewing, curve viewing, communication settings, device settings, calibration, and save/view. The curve function includes time-domain plot display, peak detection, and FFT spectrum display. |
Threshold Settings
Threshold settings allow you to set three-dimensional alarm thresholds. When the collected value exceeds the set threshold, the device will issue an alarm. Units: mT, Gs. Threshold settings can be entered via numeric keypad. Alarm Modes: None, Within Range, Outside Range. |

Curve Display
The curve displays a three-dimensional time-domain curve, and you can choose to display the curve for a specific axis individually. Below the curve, the current measurement value, maximum value, and minimum value are displayed. |
Device Settings
Time Settings: Set year, month, day, hour, and minute. Backlight Adjustment: Select between always on or automatic screen-off mode. Screen Brightness Adjustment. Buzzer On/Off. Language Settings. Filtering Method: Average Filter, Sliding Filter, None. |
Data Saving
Saving Mode: Single or Continuous. Data Callback Viewing |
Data reading software
The host computer data reading software features recording and plotting functions, automatic probe calibration/host automatic memory operation mode, automatic zero point, automatic range, threshold setting and alarm, self-setting time and brightness, and selectable display units such as milligauss and nanotesla, among many other intelligent functions.
(1) Users can use a computer to read test data and draw various measurement graphs using professional plotting software. Graphs can be sent and printed.
(2) Real-time data can be monitored on the computer using the serial port real-time transmission function.
(3) Real-time data can be queried using a fixed instruction set.
