Key Features
The HTC AL-7010 Multifunction Digital Altimeter is equipped with a wide array of functionalities to assist in various environmental monitoring tasks. These include:
- Altimeter: Measures altitude with a range of -700 to 9000 meters (-2296 to 29500 feet) and a resolution of 1 meter/feet. It also provides altitude history and graphical display of the last 24 hours, along with total altitude gain or loss.
- Barometer: Monitors atmospheric pressure from 300hpa to 1100hpa with a resolution of 0.1hpa. Features include a 24-hour pressure history and graphical display, electronic weather forecasting (Sunny, Cloudy, Rainy), and pressure trend indicators.
- Thermometer: Measures temperature from -20°C to 60°C, with selectable °C/°F units and max/min memory.
- Hygrometer: Measures relative humidity from 20% to 95% with max/min memory.
- Time Keeping: Includes Hour, Minute, Second display, a calendar with day of week, month, and date, and a daily alarm.

Getting Started and Precautions
This section outlines the parts included in the package, such as the unit itself, a battery charger, and a string. It also provides essential precautions for using the device:
- The unit is water-resistant but not waterproof; avoid submersion in water or prolonged exposure to rain.
- Keep the device away from strong magnetic forces to prevent compass interference.
- Avoid dropping the device or applying excessive force to the LCD display.
- Operate within the specified temperature range of -10°C to 60°C.
- Do not use magnetized batteries, as they can corrupt compass measurements.
Device Operation
The manual details the LCD display and button functions for navigating through various modes, including Time/Date, Barometer, Altimeter, Hygrometer, Compass, and Temperature modes. Specific instructions are provided for setting the time, date, alarm, units of measure, and calibrating the compass.
