Instruction Manual for the DZL-1G Electronic Geological Compass

Release Date:

2021-06-22

Precautions:

An electronic compass is an instrument that uses magnetic fields to determine azimuth. However, it cannot reliably and in real time distinguish between external interfering magnetic fields and the Earth’s magnetic field. Therefore, providing the compass with an environment free from significant interfering magnetic fields is crucial for maintaining its accuracy; in complex ambient magnetic-field conditions, the accuracy of the compass’s measurement data will be compromised.

This instrument is equipped with GPS functionality and can display the current latitude and longitude of the device. To use this feature, the instrument must be placed in an open area with unobstructed access to satellite signals. Obstructions such as tall buildings or trees can degrade the quality of satellite signal reception.

Warning:

This product is protected by multiple patented technologies; unauthorized imitation is strictly prohibited, and violators will be held legally accountable!

This product shall not be repaired or have its components replaced without the manufacturer’s authorization; the manufacturer shall not be liable for any consequences arising therefrom.

Data meaning:

Azimuth: the horizontal angle measured clockwise from the north direction at a given point to the line of sight to the target.
Roll angle: When the instrument is placed horizontally and rotated about its longitudinal central axis, the resulting angle is the roll angle. In other words, with the instrument in its normal horizontal position, the roll angle is the angle formed when the instrument tilts to the left or right.
Pitch angle: With the instrument placed horizontally, the pitch angle is defined as the angle through which the instrument is rotated about its transverse central axis. In other words, with the instrument initially in a forward-horizontal position, the pitch angle is the angle formed when the instrument tilts in the fore-and-aft direction.
Magnetic declination: the angular difference between geographic north and magnetic north; this value varies depending on the location.
GPS: Global Positioning System
Latitude and longitude: the latitude and longitude values of the instrument’s location in the WGS84 coordinate system.
Barometric pressure, altitude, and temperature: refer to the instrument’s current environmental parameters.
Relative height refers to the height change resulting from moving the instrument relative to a selected reference plane. When you enter the “Relative Height” display page through the operation menu, the value shown at that time is: 0 , that is, taking the height at this moment as 0 Use the reference plane, do not change the display page, and then move the instrument upward or downward; the height relative to the reference plane will be displayed.

II. Functions and Uses

This product is a portable, three-dimensional electronic geological compass that displays azimuth, roll angle, and pitch angle in real time. To facilitate field measurements, the instrument is equipped with GPS The positioning function displays the latitude and longitude of the current location; it also provides auxiliary data such as atmospheric pressure, altitude, temperature, and relative height, making it an essential tool for geologists.

This product features tilt-compensated azimuth measurement, allowing for accurate measurements even when the device is not held in a perfectly horizontal position.

This product features a low-power design that extends battery life; its enclosure is dust- and moisture-resistant and includes additional auxiliary measurement functions; and its streamlined menu layout and practical configuration options deliver a convenient user experience.

III. Product Features

3.1 Simple operation and clear, easy-to-read measurement data.

3.2 The three-axis magnetoresistive sensor measures the spatial magnetic field and features tilt compensation, eliminating the need for absolute horizontal alignment when measuring the azimuth.

3.3 Digital display, while retaining some of the functionality of a mechanical compass, offers greater flexibility in use.

3.4 Imports GPS Module: faster star search and more accurate positioning.

3.5 Auxiliary measurements of atmospheric pressure, altitude, and temperature provide more comprehensive data.

3.6 Low-power design, for daily use 1~2 Hours, workable 15 Heaven.

3.7 Delayed Auto-Shutdown Time Setting: 15s ~ 360s Adjustable; note: set to 0s , the instrument will remain in operating mode.
