1. Introdução
The Extech Instruments HW30 HeatWatch is a multi-function stopwatch designed to provide essential environmental data alongside precise timing capabilities. This device displays digital up/down timer functions, current temperature, humidity, and calculates the heat index, which indicates how hot it feels when humidity is combined with the actual temperature. It is an ideal tool for monitoring conditions in various environments, particularly those with hot weather. Additional features include a 12/24-hour clock, a standard stopwatch, 30 lap/split memory, and a programmable alarm.

6. Instruções de operação
This section details the various functions and modes of the HW30 HeatWatch.
Figure 6.1: The HW30 HeatWatch being held, demonstrating its portable and ergonomic design for active use.
6.1. Basic Operation and Mode Selection
Pressione o MODO Botão para alternar entre os seguintes modos de exibição:
- Modo de tempo: Displays the current time (12 or 24-hour format).
- Modo cronômetro: For timing events, including lap/split functions.
- Humidity/Temperature/Heat Index Mode: Shows environmental readings.
- Modo de alarme: For setting and activating the programmable alarm.
6.2 Definir a hora e a data
- No Modo Tempo, pressione e segure o MODO Pressione o botão até que os dígitos da hora comecem a piscar.
- Use o INICIAR/PARAR Botão para ajustar o dígito piscante (horas, minutos, segundos).
- Pressione o LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
- Após configurar todas as opções, pressione o MODO button to exit setup.
6.3. Using the Stopwatch Functions
- Switch to Stopwatch Mode using the MODO botão.
- Imprensa INICIAR/PARAR para começar a cronometrar.
- Imprensa LAP/SPLIT/RESET to record a lap or split time. The display will momentarily show the recorded time while the stopwatch continues to run in the background.
- Imprensa INICIAR/PARAR novamente para pausar o cronômetro.
- Para retomar, pressione INICIAR/PARAR. Para reiniciar, pressione LAP/SPLIT/RESET enquanto o cronômetro estiver pausado.
- To recall stored lap/split times, press the LEMBRAR button in Stopwatch Mode. Use LAP/SPLIT/RESET to scroll through memory.
6.4. Humidity, Temperature, and Heat Index Measurement
The HW30 automatically measures and displays humidity, temperature, and calculates the heat index in the dedicated mode.
- Switch to Humidity/Temperature/Heat Index Mode using the MODO botão.
- The display will show the current humidity percentage, temperature (in °F or °C), and the calculated heat index.
- Allow a few minutes for the sensors to stabilize and provide accurate readings, especially when moving the device between environments with different conditions.
6.5. Configurando o Alarme
- Switch to Alarm Mode using the MODO botão.
- Pressione e segure o MODO Pressione o botão até que os dígitos da hora do alarme comecem a piscar.
- Use o INICIAR/PARAR Botão para ajustar o dígito piscante (horas, minutos).
- Pressione o LAP/SPLIT/RESET button to move between hours and minutes.
- Once the desired alarm time is set, press the MODO botão para confirmar.
- Para ativar ou desativar o alarme, pressione o INICIAR/PARAR button in Alarm Mode. An alarm icon will appear on the display when activated.
