PS-50 Widescreen Display Stopwatch Introduction: The PS-50 widescreen display stopwatch is a professional timing device that integrates high-precision timing, widescreen visualization, and multi-scenario adaptability. This product utilizes advanced quartz crystal oscillation technology and a high-definition widescreen display solution, breaking the visual limitations and functional barriers of traditional stopwatches. It can accurately perform core functions such as stopwatch timing, countdown, and segmented recording, while also offering advantages such as clear readability from a distance, strong anti-interference capability, and convenient operation. Its widescreen design and high contrast display characteristics enable it to perform stably in various scenarios such as sports competitions, laboratory research, educational training, and conference management, providing users with precise, intuitive, and reliable time management solutions that meet the dual requirements of timing accuracy and visual experience in professional fields. Technical Specifications 1. Timing performance Timing accuracy: ±0.01 seconds. It adopts a high-precision quartz crystal oscillator as the time reference, with a frequency stability of ±5 ppm (parts per million) level, ensuring the accuracy and reliability of timing results Timing range: 00:00:00.00 ~ 99:59:59.99, supporting complete timing display in hours, minutes, seconds, and hundredths of seconds, meeting the needs of long-duration timing Timing mode: Includes stopwatch mode (forward timing) and countdown mode (reverse timing), with one-button switching between the two modes; countdown mode supports setting any time from 1 second to 24 hours Segmented recording: Supports up to 50 sets of segmented/lap time records, allows real-time viewing of current segment and cumulative time, and ensures recorded data is not lost in case of power failure 2. Display characteristics Screen type: 7-inch high-definition LCD widescreen, with a screen ratio of 16:9 and a resolution of 1280×720, providing clear and detailed display effects Display content: It can simultaneously display current time, timing data, segment number, battery level, and other information; the numbers are designed in oversized bold font, making them clearly visible within a range of 10 meters Display effect: Supports switching between high-contrast color combinations such as black background with white text, white background with black text, and red background with yellow text. Features automatic backlight adjustment, ensuring normal reading under both strong and weak light conditions Visual reminder: When the countdown reaches 10 seconds, the screen will automatically flash. When the time is up, the entire screen will turn red, enhancing the warning for time nodes 3. Hardware specifications Core components: Utilizing a 32.768kHz high-precision quartz crystal oscillator, paired with a 16-bit high-speed counter, to ensure stable capture and precise counting of pulse signals Power supply: Equipped with a built-in 3.7V 2000mAh rechargeable lithium battery, supporting USB-C interface charging; continuous use time ≥12 hours at full charge, standby time ≥30 days Operation buttons: Equipped with 4 physical buttons: "Start/Pause", "Reset", "Mode Switch", and "Segmented Recording". The button feedback is clear, with a low rate of accidental touch; supports shortcut key operations, enhancing user efficiency Appearance and dimensions: 200mm×120mm×25mm, weight 350g, with a non-slip rubber shell for comfortable grip and excellent drop resistance Environmental adaptability: Operating temperature range of -10℃~50℃, relative humidity ≤85%, with good resistance to electromagnetic interference, suitable for complex usage scenarios 4. Additional functions Audio reminder: Equipped with a built-in buzzer, it supports three levels of audio reminders: 1 minute, 30 seconds, and 10 seconds before the countdown. The volume of the reminder tone can be adjusted, and it can be muted for use in scenarios such as meetings and exams Data management: Supports exporting historical timing data through the USB interface in CSV format, which can be directly used for computer data analysis and archiving Auxiliary functions: Equipped with real-time clock function (displaying year/month/day/hour/minute/second), low battery reminder, automatic shutdown (after 5 minutes of inactivity), and other energy-saving designs
