1. Introducció
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. Instruccions de funcionament
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. Funcionament bàsic i selecció de mode
Premeu el botó MODE per anar canviant pels següents modes de visualització:
- Mode horari: Displays the current time (12 or 24-hour format).
- Mode de cronòmetre: For timing events, including lap/split functions.
- Humidity/Temperature/Heat Index Mode: Shows environmental readings.
- Mode d'alarma: For setting and activating the programmable alarm.
6.2. Configuració de l'hora i la data
- En el mode de temps, premeu i manteniu premut el botó MODE fins que els dígits de l'hora comencin a parpellejar.
- Utilitza el INICI/PARA botó per ajustar el dígit intermitent (hores, minuts, segons).
- Premeu el botó LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
- Once all settings are configured, press the MODE button to exit setup.
6.3. Using the Stopwatch Functions
- Canvieu al mode cronòmetre utilitzant el botó MODE botó.
- Premeu INICI/PARA per començar a cronometrar.
- Premeu 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.
- Premeu INICI/PARA de nou per pausar el cronòmetre.
- Per reprendre, premeu INICI/PARA. Per restablir, premeu LAP/SPLIT/RESET mentre el cronòmetre està en pausa.
- Per recuperar els temps de volta/intermedis emmagatzemats, premeu la tecla RECORDA 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 MODE botó.
- 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. Configuració de l'alarma
- Canvieu al mode d'alarma mitjançant el botó MODE botó.
- Manteniu premut el botó MODE fins que els dígits de l'hora de l'alarma comencin a parpellejar.
- Utilitza el INICI/PARA button to adjust the flashing digit (hours, minutes).
- Premeu el botó LAP/SPLIT/RESET botó per canviar entre hores i minuts.
- Un cop configurada l'hora d'alarma desitjada, premeu la tecla MODE botó per confirmar.
- Per activar o desactivar l'alarma, premeu la tecla INICI/PARA button in Alarm Mode. An alarm icon will appear on the display when activated.
