This document describes the WORKZONE Ultrasonic Distance Measurer, model GT-UDM-02, a multi-measurement device designed for various applications, particularly in the construction and furnishing industries. It utilizes ultrasonic technology to determine distances and offers several advanced features for efficient and precise measurements.
The primary function of the device is to measure distances electronically using high-speed ultrasonic signals. The measurement results are displayed on a double-row LCD screen, with the top row showing the current measurement and the bottom row indicating memory or calculation results. Beyond simple distance measurement, the device is equipped with a computer chip and memory function that enable automatic area and volume calculations, making it a versatile tool for professionals like property brokers, furniture designers, and craftsmen.
A key feature is its laser orientation function, which emits a red laser beam to assist users in accurately aiming at the target object during measurements. This ensures that the device is correctly aligned, which is crucial for obtaining precise results. The device also incorporates an automatic temperature comparison function. This not only contributes to more precise measurement results by compensating for temperature variations but also displays the exact environmental temperature, adding another layer of utility.
The device offers flexible measurement reference points. Users can choose to calculate the distance from either the baseline or the top of the device by pressing the /BASE key, allowing for adaptability based on the measurement scenario.
For continuous or complex measurements, the device supports addition functions. Users can add measured lengths, areas, or volumes by pressing the +/- button. This feature is available both without and with memory storage. When using memory storage, the final result can be saved by holding the MODE button for approximately 2 seconds, indicated by a double beeping tone and an "M+" symbol on the display. This allows for the accumulation of multiple measurements.
The READ button serves multiple purposes. A light press initiates a measurement, displaying the value in the upper section of the screen. Keeping the READ button pressed down allows for dynamic values to be read as the device is moved during the measurement process. In area and volume modes, the READ button is used to obtain sequential measurements (e.g., length, width, height) required for calculations.
The MODE button is central to navigating the device's functions. A brief press allows users to delete the current measurement, return to the menu, or switch between length, area, and volume modes. Holding the MODE button down for approximately 2 seconds saves the current length, area, or volume measurement to memory. This button also facilitates switching between different measurement modes (length, area, volume) and clearing current data if already present on the display, while keeping the mode unchanged.
The FT/M button allows users to switch between metric (meters) and imperial (feet) units for distance measurements with a light press. Holding this button down for approximately 2 seconds displays the environmental temperature, which can be shown in either Celsius or Fahrenheit, depending on the selected metric system.
An automatic switch-off feature conserves battery life, as the device will turn itself off after 60 seconds of non-use. This is a practical design choice for a portable measurement tool.
To ensure accurate measurements, several operational guidelines are provided. The device should be aligned at a 90-degree angle to the target surface, and a spirit level is integrated to aid in this alignment. Measurements through glass or sound-absorbent materials like curtains are not possible, and surface quality of the object can affect precision. Strong winds can also introduce errors. Objects between the device and the target can interfere with measurement accuracy. For optimal results, the device should be at least 60 cm away from the measured object, and the measured object should have a hard, smooth, and large surface. If the surface is too small, irregular, or soft, using chipboard on the surface can improve accuracy. The device's temperature should correspond to the environmental temperature for more precise results.
The device's laser is a Class II laser, and users are advised not to stare into the beam or use optical instruments to view it. The laser should only be used for aiming, and care should be taken not to shine it directly into anyone's eyes or set up the device at eye level or near reflective surfaces where the beam could be reflected into eyes. Children should be kept away from the laser.
The ultrasonic distance measurement device is designed to be maintenance-free. Cleaning the device is straightforward, requiring only a dry or slightly damp cloth. No specific cleaning agents or complex procedures are necessary.
For storage, the device should be kept in a dry and frost-free location, out of reach of children. This helps protect the internal components and ensures the device remains in good working condition over time.
Battery instructions emphasize responsible handling and disposal. Batteries are not to be disposed of with household waste but at designated collection sites. Recharging non-rechargeable batteries is strictly prohibited due to the risk of explosion. Batteries should be kept away from children, fire, and should not be short-circuited or dismantled. If a battery is swallowed, immediate medical attention is required. Correct polarity must be observed when inserting batteries, and battery and device contacts should be cleaned if necessary. Depleted batteries must be removed promptly to prevent leakage and potential damage to the device. Batteries should not be exposed to extreme conditions, such as radiators, as this increases the risk of leakage. Non-compliance with these instructions can lead to battery discharge beyond its end voltage and leakage, causing damage. In case of battery acid contact with skin, eyes, or mucous membranes, rinse the affected areas with plenty of clear water and seek immediate medical attention. Dead batteries should be removed and disposed of responsibly, and replaced with a suitable new 9V battery.
Repairs should only be carried out by authorized specialists using original replacement parts, as the device complies with specific safety guidelines. Not using the device according to the operating instructions could void the warranty. The labels on the device, including safety warnings, should not be removed.
