1. Introduzzjoni
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.

The HW30 HeatWatch requires one Lithium Metal battery for operation. The battery is typically included with the device.
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-unità.
- Uża tornavit żgħir jew munita biex tiftaħ il-kompartiment tal-batterija.
- Insert the Lithium Metal battery, ensuring correct polarity (+/-) as indicated inside the compartment.
- Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha.
Nota: Armi l-batteriji użati b'mod responsabbli skont ir-regolamenti lokali.
6. Istruzzjonijiet Operattivi
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. Operazzjoni Bażika u Għażla tal-Modalità
Agħfas il- MODALITÀ buttuna biex tiċċirkola bejn il-modi ta' wiri li ġejjin:
- Modalità tal-Ħin: Displays the current time (12 or 24-hour format).
- Modalità tal-Istopwatch: For timing events, including lap/split functions.
- Humidity/Temperature/Heat Index Mode: Shows environmental readings.
- Mod ta 'allarm: For setting and activating the programmable alarm.
6.2. L-issettjar tal-Ħin u d-Data
- Fil-Modalità Ħin, agħfas u żomm il-buttuna MODALITÀ Agħfas il-buttuna sakemm iċ-ċifri tal-ħin jibdew jteptep.
- Uża l- BIDU/WAQQF buttuna biex taġġusta ċ-ċifra li teptip (sigħat, minuti, sekondi).
- Agħfas il- LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
- Ladarba s-settings kollha jkunu kkonfigurati, agħfas il-buttuna MODALITÀ button to exit setup.
6.3. Using the Stopwatch Functions
- Switch to Stopwatch Mode using the MODALITÀ buttuna.
- Agħfas BIDU/WAQQF biex tibda timing.
- Agħfas 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.
- Agħfas BIDU/WAQQF għal darb'oħra biex twaqqaf l-istopwatch.
- Biex tkompli, agħfas BIDU/WAQQF. Biex tirrisettja, agħfas LAP/SPLIT/RESET waqt li l-istopwatch ikun waqef.
- To recall stored lap/split times, press the IFAKKAR 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 MODALITÀ buttuna.
